Insanity... or Tal style?
Posted: Wed Apr 01, 2009 8:53 am
I have been tuning eval parameters in Gaviota with "apparent" success. First ~800 fast games suggest a possible increase in ~70 elo points from the version it played in CCT11. However, look at this position to see what Gaviota played.
[D]r4rk1/1bqnbppp/pp1ppn2/8/2PNP3/2N1B1P1/PP3PBP/2RQR1K1 w - - 5 13
First move after the setup position and it played Nd5?!?!?!? What?
I do not know where the heck that came from, and clearly, the tuning did not work in this position or... did it?
The funny thing is that Gaviota kept the game messy playing like Tal on LSD and won against both Fruit 1.0 (nullmove off to dumb it down a little) and EXchess. Against EXchess it was a draw at the end but Exchess blundered the endgame.
You would assume that you give away a piece against an engine and it is over, but not necessarily. I found both games funny to watch and borderline crazy.
Games were fast (40 moves/20 seconds), but not superfast. Engines reached at least 8 plies each move.
