Many bug fixes.  Some tuning.  A big change to the advanced rabbit evaluation to try to prevent a strongly guarded rabbit from winning.  This change is very speculative, and might make overall play worse.  We will have to see.

Some bug fixes.  Still plenty of bad moves to get rid of Smiley  It's still throwing pieces away sometimes for no good reason.
 
Nice win today by jdb.  When there are not many pieces left its hard to stop all the rabbits, even when ahead on material.  Perhaps trading material when ahead is not a good idea.

There is a new one today.  I finished a referee to let me play old and new versions of speedy against each other, and that found plenty of bugs to keep me busy.
 
No major changes, just many bug fixes in the trap and goal evaluators.

Many bug fixes and minor enhancements.  Plays differently, and searches more slowly, but is not clearly stronger.

Fixed a bug that caused some bad moves in the last game against naveed, and enhanced the trap evaluation a little.  This version does much better against old versions of speedy, but that might say nothing about how well it plays against people.
 
The search is getting much slower as the evaluation gets more complex.  In my test positions, it has slowed down from 305K nps to 235K nps in the last month.  The average search depth has gone down from 11.1 to 10.6 steps.  But it does seem stronger than it was a month ago.
 
I want to thank Naveed for giving me so many good games to look at.  I wish other people would also play speedy so I don't tune it too much to one style.

Fixed a big search bug that was causing it to prune many good moves.  Hopefully this will make it much stronger Smiley  
 
Fixed a goal eval bug that affected rabbits advancing on the edge of the board.
