Subject: new Craafty beta in the works

Working on a new beta Crafty to enhance the different "levels" of play:

(see here for further info:

In this position

[D] r2q1rk1/1ppbbpp1/p1nppn1p/8/2PPPB2/2NB1N2/PP1Q1PPP/R4RK1 w - - 0 1

I was playing very cautious as the weaker levels can still beat you if you're
not careful - these games were played at a fast pace and crafty is using the
distorted piece values mentioned in the above link )which since that release
early this morning has had some additional refinments - which should go out
later tonight before I head for a 3 day vacation - away from chess and
computers.

The best move is probably something like e5 for white.

Son of a gun, would'nt you know it, this beta Crafty (in "pawn grabber" mode)
played Bxh6!?  It's NOT a killer move, but it is sure hard to find the
refutation qucikly over the board - I came back to get a winning position and
blew it later.  But I was very happy to see beta crafty play Bxh6 , although
unsound it is typical of many of unsound moves made when weaker players play -
that soemtime are hard to refute over the board - especially when you're not a
master/expert level player.

Also it very hard to dumb down crafty  without letting it play totally
ridiculous moves - but I'm getting there.
