I'll be out of town for almost 2 weeks, so speedy will be off-line until I get back.

New speedy with lots of improvements to the trap evaluation.  I can't beat it, and it did well in one game against occam, so here it is Smiley

Fixed bug in trap evaluation that kept it from protecting upper right trap in last game against belbo.

I think you should switch speedy's time control over to the one required to qualify for the Bot Challenge.  Even if you keep it playing in 30 seconds or whatever, it's worth doing so speedy gets enough games in to qualify.

Thanks for the suggestion.  I'll have to have bomb play more as well.

Either way i guess.  Only one needs to qualify, but if you want to see how good bomb is at the moment, it might be interesting to have it on.

Bomb should stronger.  They are the same program, just with different time limits on the search (20 seconds and 3 minutes).

What game would Bomb play against Bomb with a day per move?

Don't know.  At some point deeper searches can't overcome flaws in the evaluation function.  And if there is a bug in the evaluation, a bigger search makes it more likely to turn up.

New Speedy today.  The faster goal search is partially implemented.  A few positions search 3 ply goal in under a second, but most are about 2 or 3 seconds, and a few are still over 10 seconds.

The fast goal search is done, except for bug fixes and tuning.  For 3-ply goals, it finds 1/3 in under 0.5 second, and 95% under 5 seconds.

Still working on the goal search.  50% under 0.5 second now and over 75% under 1 second.  It can find some 5-ply forced goals in about 1.5 minutes, but I don't have many examples.  In real games there is usually a defender error at 4 ply from the goal, so the position 5 ply from the goal is not a forced 5-ply win.

Done with goal search for now.  It still has some minor problems, but averages about 0.8 seconds to find a 3-ply forced goal.
 
I found a couple of search bugs that might account for bomb's recent bad play.
 
Now I'll go back to the trap and pin evaluations.

Many big changes in this one.
 
I finally impemented a quiescence search, so it only goes full width to 8 or 9 steps, but it beats the old version 75%.
 
Lots of evaluation changes around pinning, avoiding pins, and escaping pins.
 
As black it opens with its camel to the side.
 
This is the code with all windows dependencies removed, so it's ready to port to Linux.
