Home * Engines * Fruit * Toga * Gambit Fruit
Gambit Fruit,
a GPL licensed, Fruit and Toga derivative open source engine written by Ryan Benitez in C++. It has some interesting changes primarily based on the last open-source-version Fruit 2.1, the goal being a fun free and aggressive chess engine [3]. Short after its release in end of 2005, Ryan joined forces with Fabien Letouzey and Joachim Rang for a commercial Fruit, and incorporated Gambit Fruit features into Fruit 2.2 and subsequent versions.
Added Features
and changes in Gambit Fruit:
- Alternate piece-square tables
- Rook pawn score adjustment
- Rook Bishop bonus
- Queen Knight bonus
- Two Rook penalty
- Two Knight penalty
- Minor tuning of piece values
- King tropism
- Side to move bonus
- Rook on bad pawn file bonus
- Pawns on Bishop colour penalty (fewer pawns is better for bishops and with one bishop you should not block it with your own pawns)
- Improved pawn structure
- New Lazy Eval
- Rebel reductions with re-searches [4] [5]
- Bitbases (using Scorpio bitbase files)
- Contempt factor
Acknowledgment
Thank you to Fabian for Fruit 2.1, Thomas for Toga, and to Bryan Hofmann for the Windows compile [6].
