This is the speedy version of the bomb that will be in the competition.  But you have to play it at the same time limit it's using.  I think it will be unbeatable at this speed.
 
I fixed some bugs in the quiescence search, and made some other minor improvements.

This speedy is running on an old 700 MHz machine without much memory.  The old speedy was running on my 2.4 GHz machine.  So this speedy is is getting less than 1/3 of the time of the old speedy, and is typically only searching 7 steps full width.

Great move and great work you put in there. Thanks.
 
It's cool to play Speedy and it had been a long time.  Today it definitely was stronger than me at 30s per move.

It's known from chess that the computer's rating is higher at fast games than slow games, so I expected that with equal time and faster games, that speedy would rank higher.
 
I'm out of town for a few days, so speedy is back on the fast computer until I get back.  That should make it a little stronger.
 
If anyone notices some general weaknesses it has, please let me know.

David, if you haven't already, you might like to take a look at the game Jarrausi played most recently against speedy (there are some comments attached).  Basically there's a repetition detection error in speedy somewhere.

Thanks.  I noticed it, but it was too late to change it right before submission.  My board hash includes the side to move, so I need a separate hash for the repetiion rule from the one that I use for the transposition table.

Speedy and Bomb will be off-line until after the human world championship match.  Since I am not allowed to change the program until then, it seems fair to avoid additional games with the human challenger.  He could learn from those games, but I would not be allowed to put anything I learned into the program.
 
Bomb will be available after the match is over.
 
I'm going to switch back to working on computer go for a while.
 
Thanks for all the games you all played that helped me improve the program.
