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
