9/7: 8:50 PM (california time)
Fixed the lose on time bug again (hopefully correctly this time).
Rewrote the trap evaluation. Style of play around traps should be different. Should avoid camel getting stuck by enemy trap. Should avoid using strng pieces to trap enemy weak piece on a trap. The evaluation constants are very, very different, so it might play better, or it might play worse 
Fixed a goal evaluation bug that let Claude sneak a pawn through when he was behind in material.

New version 9/8, 10:35 PM
Fixed a few bugs in trap evaluation from today's games. Naveed's strategy is very hard to counter with
speedy's search depth.

Added a trap search extension. Might make it weaker or stronger, who knows?

9/11
Fixed a bug that made it advance weak pieces only when gold. This is why it has lost more games as
gold recently.

Another big change to the trap evaluator. We'll see if it helps.
Thanks everyone for all the games. They help me a lot to find bugs.

Improved time control. You will see more variation in the time used per move.

Another rewrite of the trap evaluation. Should be much more difficult to drag a piece to a trap and pin it there.
Please give it a try so I can find the bugs in the new code

Last night I accidentally set the time control to 0 seconds, so speedy was doing very little searching.
Same version this morning, but with the correct 20 second time control. It probably has some major bugs as well, since I was just as tired when I was writing the code as when I was setting the time control
