[Joerg Oster]

Do you use contempt=0 or contempt=20 for stockfish?

I understand that contempt=20 is good for rating lists when many games are against weak opponents but probably not for a match against Komodo.

Contempt=20 is one of the latest changes by lucas.

http://abrok.eu/stockfish/

Is this 20 centipawns or 20/256 pawns? If it is 20/256 the match should be pretty much unaffected by contempt since Komodo's default is 7 centipawns, which would be 18/256.

It is really 20 centipawns. The conversion into Stockfish's pawn unit is done internally.

[Uri Blass]

Why did black play 53....Kf5(???)?

It is a strange move from human point of view but change nothing.

White can win even after more normal move like 53...f5 because white capture all the black pawns and black cannot protect both promotion of the b,c,d pawns and the black f,h pawns

Practically even only protecting against the b,c,d pawns is too much for black
and after 54.Kb4 Kd7 55.Ka5 Bb7 56.Kb5 black is going to be in zugzwang
in a few moves and 55...Kc8 56.Ka6 Kb8 does not help black because 57.b7 is winning for white(advanced king with 2 passed pawns in the 6th rank is enough for win).

[Graham Banks]

GAME 15 - Stockfish chose to give up a pawn in the opening to exert pressure on the passive black position. It won the pawn back, but the resulting wholesale exchanges resulted in a drawn endgame.

GAME 16 - Stockfish gave up the exchange to keep an enduring hold on the position. However, it was unable to make anything of it and the game eventually ended as a draw. Komodo still 3-2 up in the match.

GAME 18 - Komodo grinds out a win to go 4-2 ahead in the race to win six games. After Komodo created a central advanced pawn early in the game, Stockfish sacced the exchange during the middlegame to go into an ending with the bishop pair against rook and extra pawns. Komodo's rook managed to tie down Stockfish while the king walked over to help administer the coup de grace by forcing the win of a bishop.
