Komodo 2.03 is supposed to know about this ending but we discovered a bug immediately after release which has been fixed. I checked this position and the latest development version of Komodo will not play that move and when I force it in Komodo immediately reports a draw.Max wrote:Just watched a game between Komodo and Stockfish at my little tournament on Samsung Galaxy Tab with Aart Biks great new Chess for Android 2.9 gui. Komodo outplayed Stockfish and reached this position
[d] 5R2/8/1Bk5/P7/4K3/8/r4p2/8 w - - 0 57
Komodo blundered now with 57.Rxf2? and Stockfishs evaluation moved up to 0. But to my surprise Stockfish 2.11 did not go for the exchange and played Ra3? with -6.58 after 10 seconds.
So there was a bug, not in chess for Android but in Komodo.
Chess for Android setup:
- level 4 (with 10 s/move)
- no tablebases
- 32 mb hash for every engine
Looked a bit strange to me, that Stockfish always moved after about 10 seconds. While Komodo used his time more intelligent and takes between 1 and 33 seconds.
Is there anything broken in the time management of Stockfish for Android?
