Time per turn:
ms
The amount of time given to each player to find a best move. Up to a point, smaller numbers tend to give an advantage to the Asm.js optimized code.
Skill Level:
20
The effective skill of the chess engine. Level 20 is the strong and 0 is the weakest (multiple intentionally bad moves).
Contempt:
0
Roughly equivalent to "optimism." Positive values of contempt favor more "risky" play, while negative values will favor draws. Zero is neutral.
