This game again show problems in stockfish's evaluation.

black is only a pawn up but stockfish shows evaluations of more than 5 and even more than 6 pawns for itself.

Thank you very much for your report!!

I've tracked down the problem and it is indeed not at all related to time management. It results from overflow issue which was already fixed in devel-branch few days ago. The fix will be included in maintenance release 1.5.1 which will hopefully be released soon :)

Great news, thanks !

If Stockfish 1.5.1 score 0.5 more points than 1.5 every 100 games, that's +3.5 elo :-)
