BikMove v1.2

Continuing the detour in checkers. I also released v1.2 of BikMove, a checkers engine plugin to Martin Fierz' CheckerBoard application. New features include:
  • Added internal iterative deepening to search
  • Configurable transposition table and endgame database cache
  • Improved evaluation function
  • Avoid querying Fierz's database when *either* side can capture
Below are results of a 3-move openings match between BikMove v1.2 and other engines (1 second-per-move, 256MB hash, 256MB database cache, 2-8 piece endgames, best-move for engines that have their own book).

BikMove v1.2 vs. Easy Checkers 1.0   : W-L-D: 284-  0-  4  99%
BikMove v1.2 vs. Simple Checkers 1.14: W-L-D: 136- 21-131  70%
BikMove v1.2 vs. GUI checkers 1.05+  : W-L-D:   9-108-171  33%

BikMove v1.2 vs. Cake1.8 + huge book : W-L-D:   0-152-136  24%
BikMove v1.2 vs. Kingsrow 1.16d      : W-L-D:   1-181-106  19%

For comparison, also some results under similar conditions with v1.1.

BikMove v1.1 vs. Simple Checkers 1.14: W-L-D: 75- 64-149  52%
BikMove v1.1 vs. GUI checkers 1.05+  : W-L-D:  6-183- 99  19%

This game sucks you only win by mastake the defencive ponds can move diagonally but you can't its frustrating so What's the point I mean really at least make it so it doesn't memerize every move every time you play so at least you have a chance cone on now and now I can't even leave a comment. ?f in rediculis

Sigh. I assume your comment refers to my chess application, and not to this particular posting. The "defective" pawn move most people complain about is called en-passant, please have a look at this posting. And the reason you don't see your comment right away is because I moderate it first.
