Took me 2 seconds, since it was hashed . I remember this position from long ago. Stockfish took 10 times as long.

[overlord]

Just few seconds, because it is well known positions

[AdminX]

I didn't have a stop watch, but I would say it took me under 30 seconds to see the winning move. Komodo saw it it under 5 seconds on my system.

Gandalf 6 on my 2.9 GHz i7 does quite well here:

A development version of Myrddin at 4 cores did very well here, but this seems to be a lucky run and the results are not 100% reproducible:

Unfortunately, the next three runs all found the move in around 25 seconds. Ah, the joys of my wacky SMP implementation....

[fern]

This is a well known sacrifice....the interesting thing today is to find the second best move for white....Which perhaps is Knight moves, check, pawn x Knight, Q check in g3, etc

I doubt there is a computer chess person on the planet that doesn't know Botvinnik's move in this position. Turns out it is a completely trivial move for a computer to find, but it is/was difficult for humans that have never seen the position since it throws away the bishop instantly.

Crafty sees this in under a second on 4 year old hardware. In fact, it sees it in milliseconds with a draw score, then sees a big win in material at depth 19, a fraction of a second...
