Although there have been many efforts at chess programs for the 6502, some rather strong and some rather successful, most weak chess programs don't necessarily make a good chess partner for a weak human
At one time anyway, the Fritz
chess engine had a "tactical presents" mode, where the
chess engine actively tried to get itself into reasonable-looking but tactically flawed positions. A light would light up on the board, indicating that a key tactical move was present.
Since this is a 6502 board, I will mention in passing that Colossus
Chess 4, by Martin Bryant, was probably the strongest 6502
chess program of its day. It had a surprising number of modern features, including pondering.
The great grandaddy of all 6502 microcomputer
chess programs is, of course, Microchess.
