In the following game that is posted also in another thread Rybka3 played 53...a3(unexpected by stockfish) and got an advantage(Rybka3 did not win it but I thought it may be a good test position to see how much time stockfish needs to find it)
.
Stockfish understood it immediatly at move 54 based on the pgn
so I decided to test it at infinite analysis to see how much time stockfish needs to see 53...a3(I used 256 mbytes hash)
I was disappointed to find that it needs a very long time to find 53...a3
I remember that at some big depth (not sure if 23 or 24)
stockfish used many minutes for 53...a3 and I believed that it was going to find it but unfortunately it did not find it.
Note that getting negative score for white with clear hash after 53...a3 is easy for stockfish and it may be interesting to know what is the problem.
