I wonder what cause hanging piece to be ranked so high.
I admit that it took me significant time to see that I can capture the bishop(motr than a minute not considering time of checking the solution)
but I did not come close to thinking 93 minutes for the problem as one of the solvers did based on the comments and on his history(I looked at the history because I thought maybe he meant 93 seconds because 93 minutes is a lot of time even in my standards).
