As computer chess programmer, Joël Rivat is early bitboard proponent, and author of the strong chess program Chess Guru. He started chess programming in conjunction with C. Marche, G. Le Blanc in 1990, and rewrote everything using bitboards. After Robert Hyatt started using bitboards too, discussions and sharing new ideas permitted to improve the technique considerably. || toc =Selected Publications=
