It's not necessarily a repetition but one or more delaying moves which produce the same result. But to adjust the score shlightly to draw eg by score -= score/32 seems dangerous, even if abs(score) < SOME_THRESHOLD. During Opening that happens quite often. I remember the svechnikov, where e5 and Bg5 occurs via e7-e5 Bc1-g5 or e7-e6 Bc1-f4, e6-e5 Bf4-g5. Gerd
