- The engine Drawmaker is tested in the GUIs Winboard and Arena
The only goal for this engine is not to lose a match Its values have not the same meaning as in normal chess engines, i.e. if it has a value of +158 (centipawns) it doesn't mean necessary, that it sees a forced win: it can be the case, that it sees a forced draw (by repetition or stalemate) The engine is based on SF fork ThothFish, with pessimistic contempt value, values for echanging pieces, and in the code there are some draw_values changed by mate_values (only for evaluation, because it would be an unwanted side effect if the engine would announce mate when it sees a forced draw)
Try it out, and if you have a lost game of Drawmaker that it played very weak, you are free to post it in the forum, and I will try to optimize the settings Engine Reviews - camava wrote:
- Hi sugarboy,i already played some end games,and drawmaker gets the move for make the play long,but no the move to draw.
Sample: tablebase shows next. Kf1 draws Kf3 lose Mate#10 Kd3 lose Mate#9 Kd2 lose Mate#8
Drawmaker choose Kf3,not Kf1 All engines do that. Download Here | |
