Open source chess engine based on Fruit 2.1 sources and other's people modifications that plays fun and aggressive games
GambitFruit with a taste of Toga
(Just an experiment to make a blitz engine as GBF4bx is good in blitz using Toga' search and GambitFruit' evaluation.
GBFruit likes to draw but is a hard engine to beat! This is part of my oldies upgrades for single processors. This is one of my favorite Ryan Benitez' engines.)
- added Razoring from Toga 1.4beta5c
- used Futility pruning from Toga 3.1.2 SE
- used History pruning from Toga 3.1.2 SE
- used material values from toga 3.1.2 SE
- egbb path at c:/egbb/

----------------------------------------
I think Pawn Shielding, King safety, and tropism can all be tuned for better results.
To turn off Lazy Eval set Chess knowledge to 500.
If you have any suggestions for piece square tables please email them to me.
I plan on giving many piece square tables to choose from for each piece in UCI options in future releases.
For bitbases please go to the Scorpion download section at https://wbec-ridderkerk.nl/index.html
Put the bitbases in the egbb folder and make sure you have the egbbdll.dll in the folder with the bitbases.
For an opening book goto https://chessbazaar.mlweb.info/fruitbooks
Added:
• Alternate piece square tables
• Rook pawn score adjustment
• Rook bishop bonus
• Queen Knight bonus
• Two Rook penalty
• Two Knight penalty
• Minor tuning to 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 researches
• Bitbases (using Scorpio bitbase files)
• Contempt factor
• More tuning options
• Other small changes that likely affect nothing
Todo:
• Pawn Ram handling
• Tune extensions and reductions
• better draw recog
• Tune king safety with tropism
• SMP
• Clean up my bugs added to Fabians great code
Thank you to Fabian for Fruit 2.1, Thomas for Toga, and to Bryan Hofmann for the window compile.

Une IA de jeu d'échecs libre et assez puissante, par Ryan Benitez, ajouts de Denis P. Mendoza.
En C++.
GambitFruit (GBFruit) est une IA de jeu d'échecs (une IA spécialisée dans ce type de jeux) libre et multi-plateforme, assez puissante (puissance estimée à 2700 Elo), dérivé des moteurs Fruit et Toga avec des améliorations.

Moteur d'échecs open source basé sur les sources de Fruit 2.1 et les modifications apportées par d'autres personnes, qui permet de jouer à des jeux amusants et agressifs
GambitFruit avec un goût de Toga
(Juste une expérience pour faire un moteur de blitz car GBF4bx est bon en blitz en utilisant la recherche de Toga' et l'évaluation de GambitFruit'.
GBFruit aime dégainer mais est un moteur difficile à battre ! Cela fait partie de mes anciennes mises à jour pour les processeurs simples. C'est l'un de mes moteurs préférés de Ryan Benitez).
- Ajout de Razoring de Toga 1.4beta5c
- utilise Futility pruning de Toga 3.1.2 SE
- utilise History pruning de Toga 3.1.2 SE
- utilise material values de Toga 3.1.2 SE

Gambit Fruit,
un moteur open source dérivé de Fruit and Toga, sous licence GPL, écrit par Ryan Benitez en C++. Il comporte quelques modifications intéressantes, principalement basées sur la dernière version open-source Fruit 2.1, le but étant d'obtenir un moteur d'échecs amusant, libre et agressif. Peu après sa sortie fin 2005, Ryan s'est associé à Fabien Letouzey et Joachim Rang pour un Fruit commercial, et a incorporé les fonctionnalités de Gambit Fruit dans Fruit 2.2 et les versions ultérieures.
