>What is the maximum possible count for legal moves from any position >in a chess game? Has anyone ever calculated this? >Can it be greater than 256? blass's calculation about maxima is correct. Of course, there is no guarantee such a position actually can exist. Actual numbers are much lower, and I believe there is a good chance all the below are correct. I have looked closely at all the following, and challenge anyone to better any of them. No fairy chess stuff. I guess the 219 quoted in this thread is possible. Per Maerchenschach ... A.Dickins: 1. no promoted pieces, without promotion moves: 109 white moves (W.Cross 1967) 5k2/2K5/3N1B2/P1NB4/6Q1/4R3/P1PP1P1P/1R6 w - - 0 1 2. no promoted pieces : 144 white moves (J.Ban 1960) n1r1r1b1/1P1P1P1P/1Q6/3NBNK1/R7/4p1p1/3PBPkP/2R5 w - - 0 1 3. with promoted pieces : 218 white moves (A.Dickins 1968) 3Q4/1Q4Q1/4Q3/2Q4R/Q4Q2/3Q4/1Q4Rp/1K1BBNNk w - - 0 1 4. with all 32 pieces : 99 white moves (H.H.Cross 1946) q2Q3r/n6R/kpB1N1K1/p1p1Bppp/1PN3P1/1n1pp1b1/P1PPPP1P/r5Rb w - - 0 1 Mate comes quickly in these! Records where there is no mate in 1.2 would be interesting. Kind regards fca
