Problem 30933

[drahacikfm]

This problem should be disabled immediately.

Solution given is 1...Rxf1+ leading to a winning King and one pawn versus King and one pawn ending.  But 1...Kc5 and 1...Kd5 are completely winning too.  They lead either to exactly the same winning pawn ending, or in 3 moves Black will have rook, knight, and pawn against rook, which a 1400 player could win against a Grandmaster.

I lost rating points on this, playing 1...Kc5.  Grrr

That is an annoying one.  This is passing the filter for similar reasons to others mentioned today.

I just got this one right,  but I'd seen it previously.  I can't remember if I got it wrong previously and loaded it into my chess computer or maybe I saw this discussion.  Either way, I only got it right because I remember the correct sequence luckily enough.  There's definitely more  than one way to skin this cat.

The new generator hasn't got to this one yet, but I'm confident when it does get to it that  it will be filtered (or kept with those two alternative lines marked as alternatives depending on how good the 4th best move is).

Regards,
Richard.

I know you all see the point of the problem, there are about 3+ variations that are winning but the best one is a completaly forced variation.
