Uri Blass training's diary

[uri blass]

I won yesterday against an old IM(in the past member of the israeli team for the olympiad)

He has fide rating of 2252 but israeli rating of only 2120.

http://ratings.fide.com/card.phtml?event=2800799

My trainer told me that he looked at games of players from kaldor's time and his opinion is that IM in 1975 is only level near 2200 today so it is not that he got significantly weaker and he only got slightly weaker relative to his level in the past.

Note that I did not feel well when I went to play and I still do not feel well but my team had no replacement for me so I went to play.

I thought during the game that I am going to offer a draw if I get a small advantage.

In the opening I got a clear advantage and with clear advantage I wanted to win.

Later I did not play well and Kaldor got the advantage.
I defended well and when I thought that I got at least equality on the board but was in big time trouble (1 minute on the clock +30 seconds per move) I decided to offer a draw it was in the time that I did move 48.

Kaldor rejected the draw offer and later at move 56 said now I offer a draw.
Inspite of not feeling well and being in big time trouble I decided to decline the draw offer because I saw that I win a pawn and I decided that I accept a draw only if I have a small advantage and not if I have a big advantage and I won the game.

Even though you try to downplay it, a win against an IM is a win against an IM. Good job and congrats 

[munich]

Would you dare to post that game? Blunders or not - I dared to post my game, too. Rybka/houdini/stockfish etc.... - they all find afterwards even better moves, but that´s what we are: humans.


I had once a won game against an IM, too. It wasnt an offical game, just a 10 minutes each game at his home.
Actually I was visiting his daugther and she told me her father plays chess, too, and he is a real international master. I never heard of his name before, which made me a bit sceptical.
Then she asked her father to play against me. He didnt want to, but she insisted and that how we came down to play.
I was better in the opening, and I got a good attack on him. During the game I realized that he was nowhere a real master, most probably never been in close to a master in his whole live.
When I had the opportunity to check mate him, I decided not to humilate him more in front of his daughter (who was watching us), made a stupid mistake on purpose and blundered my queen. After the blunder I said, oh, well, there had been a mate if I had not blundered. He denied that. Then I showed it to him. Then he agreed.

Later in live I had a few rare occasions to play against him. Meanwhile I knew him. He was a real master. A strong master even, but I am not sure about his elo. Could have been about GM strength. I never ever had a won position against him again.
:-)

Possibly he didnt want to humilate me in front of his daughter? I will never know.
I am trying hard to remember the sir name of him (or his daughter).
Back then I was 16 years old and had an elo of around 1700-1800?
Edit: his name was enigl, or Egl, or egli or eggli - but I cant find him. Anybody knows an IM with a similar name?

[uri blass]

The reason that I do not post the game is that I do not want to expose my opening and future opponents may read here and prepare better against me even if the chances are small.

I play a new opening with black(my first game in that opening is from june 2012) and so far I have 9 out of 11 in that opening(most of my opponents were weaker than me but 9 out of 11 is still impressive).

Here are israeli rating of my opponents including my own results:
Israeli rating are now slightly higher than fide rating based on statistics of people who have both fide rating and israeli rating.

2700 israeli rating is equivalent to 2700 fide rating but every 100 points in fide rating seem to be equivalent to 107 points in israeli rating.

My results:

1)1734 won(practically my opponent had no rating and he got clearly better endgame but lost)
2)1872 won
3)2215 lost(my opponent got advantage and later I got the advantage even if not enough for winning but I did the last mistake)
4)1983 won
5)2142 won(my opponent had a decisive advantage after he sacrificed a piece but lost because he did not find the right moves)
6)2131 lost
7)1992 won(I rejected a draw offer in slightly inferior endgame and later won because of a blunder of my opponent in the endgame in clearly better endgame but probably still drawn endgame and not a stupid blunder)

I posted about the mistake in the israeli site(you may not understand the language because it is in hebrew but
I hope that you can see the diagram and try to find the only logical losing move)

http://www.chess-il.com/forum/viewtopic.php?f=15&t=20635

8)1950 won(my opponent got a decisive attack but did not play well later so I won the game
9)1840 won
10)1832 won(my opponent missed a win)
11)2120 won

I may decide to post later part of the game not including the first moves.

[uri blass]

optical illusion that happened to me in the last game(I was clearly worse and I do not claim that I lost because of it)



Note that it was clear to me that I have no good alternative to Qd7

I calculated the line Qd7 Rd8 Qxa7 Rxd1+ Nxd1 Qc1 Qa4 and did not like it because I saw that I lose e4
I went to the line Qd7 Rd8 Qxa7 Rxd1+ Nd1 Qc1 Qb8+ Kg7 Qd6 and saw that I lose because of Bd2

I went back to the line Qd7 Rd8 Qxa7 Rxd1+ Nxd1 Qc1 Qa4 and suddenly thought that I can play Qc2 because I imagined that the queen at c2 is defendend by a bishop at d1(of course there is a knight at d1 and not a bishop but knight and  bishop are pieces with equal value.

In the game after Qc1 I understood that I have no Qc2 and it seemed to me suddenly that black wins a piece by Nc5 or b5 with Nc5(practically black win but needs to find a better move not to be only a pawn up so Qa4 gives me the best practical chance but at time trouble I decided that inspite of Bd2 maybe I have some chances that I do not see because I have some options to make check to the opponent king so I decided to play Qb8+ and of course lost very fast.

It seems that I still have problems with 1.d4 and note that I played as munich suggest again stronger players but it seems that it is a bad advice because strong players usually have better positional understanding than me so if I get to unclear position it is usually position that is an advantage for the opponent.

My opponent was Irina len who is slightly stronger than me and I do not think that she is stronger than me at tactics
and my guess is that she is stronger than me at positional understanding.

http://ratings.fide.com/card.phtml?event=2805715
 
Here is part of the game and note that my e4 move seemed to me what munich suggest against stronger players.

In the game I understood that I have some problem with my pawn structure but I thought that I have better mobility and king safety.

practically my trainer say that the black knight at e6 has better mobility than the white knight so I have no advantage in mobility and g6 that I considered as weakness for black is not significant weakness in king safety because  the black knight protects well against it.

[uri blass]

Note that in this game 29...Qc2 was stronger and practically 30.Qa4 was a better practical chance.
black needs to find Qd2 in order to win easily in that case because with endgame with pawn down white may have at least practical chances.

I do not plan to avoid position when one side has one type of advantage and the second side has a different type of advantage and the solution is simply to have a better positional understanding and to understand what type of advantage is more important.

In the game I also played 15.e4  not because of playing against a stronger opponent but simply because I thought that it is better for white and later I got to time trouble because I found nothing good for white(there was one good move that I could play that is 22.Nd5 that almost equalize and I considered it but simply did not calculate deep enough to see that it is good after 22..cxd5 23.exd5 Bg5 24.Qh3.

It is hard to see it because black has many moves with the knight and it seems that at least one of them is winning.

[uri blass]

I decided also to post part of the game when I beat IM Avraham kaldor(rating of only  2120
but he deserves rating above 2100 based on his result and he has 3 out of 5 in the israeli league when the game against me is his only loss and he may earn rating in the next israeli update inspite of the loss against me(rating 2053) because he has 2 wins against players with rating of 2052 and 1943 and 2 draws against players with rating 2142 and 2224)

The draw against 2142 was a draw against Irina len who beat me in the last game in the israeli league when I also posted part of the game.


Note that 35...Rgd8 was a mistake and I missed at time trouble Rgf1+ Ke7 Rf5 and white wins a pawn but kaldor also missed the right move

I offered a draw together with 48...Bf8 that kaldor rejected and later kaldor offered a draw together with the move 56.h3 but that time I rejected the draw offer inspite of serious time trouble when I had only 1 minute on the clock+30 seconds per move.

[oded ross]

My opponent was Irina len who is slightly stronger than me and I do not think that she is stronger than me at tactics
and my guess is that she is stronger than me at positional understanding.

I know her pretty well as you know, and your assumption about her positional understanding is probably correct.

[munich]

because strong players usually have better positional understanding than me so if I get to unclear position it is usually position that is an advantage for the opponent.

I am not sure if this is really true.

However, even if it is like that it appears to me like this:

stronger player: tactically = equal (2100 elo), positionally = stronger (2200 elo)
you: tactically = equal (both 2100 elo), positionally = weaker (2000 elo)

What kind of position shall you seek

a) positionally: you have a gap of 200 elo positionally
b) tactically: you have no gap to close (gap = 0 elo).

Of course there is hardly a pure positionally and tactically position, but positional elements still matter in tactical sharp positions. Nevertheless, I feel, that in this very case you better look to carry out your battle on tactically waters than in positionally waters.

But what if your quote is wrong? Then it behaves the opposite. Still: tactics can go wrong. You see s.th. good, go into it, just to find out 3 moves later that it isnt so favorable at all. The weaker opponent does not need to see the hole in your tactics when you start your tactic. He only needs to find the hole when the situation arises.
It reminds me a bit of 2 CT puzzle versions: same tactic, but the more difficult version starts 1 move earlier.

Tactics are always a bit "shaky". You can get away "lucky". If there is anything like "bad luck" in chess, then it usually can be found in tactics that went wrong.
 
It went wrong for you in above game. Tactics can go wrong on both sides. If you are both equal, then the statistics should give you a 50% chance. If you'd go for pure strategic with hardly any tactics, then you wont achieve these 50%. But that does not mean you will score MORE than 50%, but rather it means you score much less.

[uri blass]

My guess is that my main problem is in evaluating unbalanced positions and that if the position is balanced I
am not weaker positionally so it means that the best strategy is probably to avoid unclear positions if I have an alternative that is not against me.

I do not like this solution and the better solution is simply to improve my understanding of unbalanced positions.

[asterion]

You may want to look at a similar plan but with Nd2 rather than Ne5 

[uri blass]

I give a link for pictures of people who play in one of the torunament that I play together with prizes from previous tournament when I won the first prize
See the link at the bottom of this post.


I know that most of the readers cannot understand hebrew but you do not need to understand hebrew to see the  pictures.

There are no money prizes in that tournament and it helped me to win the first prize with 7.5 out of 9 because stronger players participate when there are money prizes and usually even when I win some money prizes it is not first prize
and I am not at level that I earn money from chess and money prizes that I earn in average(The average has 0's
in  many tournaments) are even not enough to cover participation fees.
 
I appear in the 2 pictures at the top of the screen
The person who sit on the chair in one of these 2 pictures is the oldest active israeli chess player(98 years old in this year)

You can also see the female player who won second prize with 6.5 out of 9 and was the only player who beat me in that tournament after I rejected a draw offer in an equal endgame and later missed a win and did another mistake and lost.

You can also see most of the players in the next tournament that started immediately after the tournament that I won first prize.
so far I am not very happy with my result in that tournament and I have only 3 out of 4 with 2 wins and 2 draws.

[uri blass]

today I drew against the following player in a long game
http://ratings.fide.com/card.phtml?event=11600543

I decided to post the game because my opponent did not play something normal so I do not expose too much about my openings.

Note that my opponent blundered in some move and I could win  but I missed the win and did not get another chance.
I am sure that I could find the winning move easily in chess tempo but when I play a tournament game things are different.

[kuuga]

May I suggest you read Silman's "How to Reassess Your Chess" or "The Amateur's Mind" if you have not already? He focuses on imbalances in those books. I prefer the first.

[uri blass]

summary is that the tournament that I played that is also for fide rating was very bad for me.

played against 5 opponents when all of them have fide rating 2000-2100 and scored only 2 draws and 3 losses.

I am not going to give the games but can say that in all the games I got an advantage in some stage.

round 1
my opponent had fide rating of 2059 but he is better than his rating and scored 3.5 out of 5 against strong players
when 3 of his opponents had rating above 2200
http://ratings.fide.com/card.phtml?event=2811820

I got some positional advantage from the opening but lost when he simply played well and I do not feel that it was a bad game of me.

round 2
draw that I posted here when my opponent was an old player with fide rating 2066

http://ratings.fide.com/hist.phtml?event=11600543

I missed a win by 16...Bxh2+

round 3
My worst game in the tournament

played against a young player with fide rating of 2074
did a positional mistake in moves 11 my first move when I started to think because I did not remember theory in the relevant line.

Inspite of it my opponent did a mistake later and I could get the advantage.

unfortunately I blundered at move 22 when I missed the fact that 22.e5 is losing against Nh3+ and I already saw earlier that 21.e5 is losing against Nh3+ with exactly the same idea

move 21 was a good move for the wrong reasons.
I saw 21.Bxf4 Bxf4 22.Qxb4 but thought correctly that black has a compenation for the pawn because he controls the c file

I did not like it so decided to play 21.Rac1 first with the idea to win the pawn later by the same way.
21.Rac1 was a good move but not for the reason of winning a pawn and it turns out that after 21.Rac1 Qb8 22.Rfd1
I have the advantage.

only after 21.Rac1 Qb8 I understood that 22.Bxf4 does not work and I thought wrongly that black is better
and after considering some options prefered 22.e5 forgetting about the line of Nh3+ that I saw earlier.
37.Bxa7 was a mistake that lose the game after Bxa7 38.Qf7(the move that I planned) Bg1+
The worst mistake is the beginner mistake 38.Qf7

Note that both of us were in time trouble and played on the increasement of 30 seconds per move and  I simply did a mistake of not calculating what happens after he captured the queen because I assumed wrongly no difference between bishop at a7 and bishop at c7

I give that part of the game as pgn

Note that I saw that 24...Qc6 is not good because of 25.Qa5 but missed Qa5 when I played 26...Qd7
The psychological reason is that Qd7 threats the rook so I thought mainly about rook escape of defending the rook.

My opponent missed 32.Qxc6+ that I saw during the game and later could also win for example by 33.Qa5
33.Be5 was a mistake and I got a better endgame.

I missed my chances to win when at time trouble I missed the simple idea of 47...Rh8 and Rxh7 and later
48...d4 49.Kf4 d3 50.Ke4 Rh8(unfortunately I calculated only c1=Q that lead to a draw)
and my last chance was 50...Re8 51.g4 d4 52.g5 d3 53.g6 d2 54.g7 d1=Q when I am not sure if black win but black has winning chances)
