SD Chess,
a chess program developed in 1977 by Ira Baxter from Software Dynamics, written entirely in SD Compiler Basic on a 6800 microcomputer, using a minimax tree lookahead scheme 1. To simplify the move generation, SD Chess stores the chess board in the middle of a 12 by 12 field, with the borders filled with white pawns 2. SD Chess competed in the Microcomputer Chess Tournament of the Second West Coast Computer Faire, March 3–5, 1978. A program called Chess D by Ira Baxter was on the Stand-By list of the WCCC 1983 in New York 3.
