KMT Chess updated to 1.2! About 100-150 ELO stronger

[P. Villanueva]

Hi all!
I´ve just released 1.2 version of my engine KMT Chess. Can be downloaded here https://sourceforge.net/projects/kmtchess/.
The new release is 32bit (but it´s stronger than 1.1 64bit), the 64bit build will be released very soon.

Most significative changes:
- Pondering capable.
- Polyglot opening books compatible.
- Piece values changed. This avoids some very weird piece changes that 1.1 sometimes did.
- Pawn evaluation improved, now KMT build stronger pawn structures.
- Search depth improved in endgames.
- Now the king goes into the battle earlier in the game.
- Fixed a nasty bug that allows occasional calls to quiesce() when in-check.

In a 200 game match 1.2 vs 1.1 the results were: 116-47-37 (67%).
I guess that 1.2 ELO is about 2250-2300

Enjoy it!

Thanks.

It doesn't support Editboard/Setboard mode in Arena for EPD testing. I hope this will be implemented as a fix.

- Now the king goes into the battle earlier in the game.

This sounds a little risky to me. Usually the king must be in the corner in the middle game.....

Thanks all for your interest!

I supports setboard but doesn´t support analysis mode. I have work very little on usability. This will be fixed soon.

Previous versions were too much conservative. I´ve noticed some losses due to late king activation. I´m not sure if this single change improves KMT strength. The ELO gain (or lose) should be small and need big tests, and I don´t run tests bigger than 200 games.

Thanks, Paul. I'm looking forward to it!
