Placing w Bishops: 24*24 worst case When the pawns take more white than black squares, you get numbers like 23*25, which are always smaller. >placing black w Bishop in average: 15 >placing black b Bishop in average: 15 23*23 >placing 2 white Knights: 28*27/2 20 squares taken now, leaving 44 empty. so 44*43/2 etc. >e.p. is possible or not 2 >affected e.p. file 8 So, ep needs 4 bits. My inclusion of ep needs less, namely 17^8 / 15^8 = 2.7, so less than two bits. >castling rights (s+w) 4*4 4 bits for castling. Again my estimation (encoding castling together with legal KK position) needs less. 2*17^8*23^2*24^2*4096*42!/(32!*2*2*2*2) = ~ 2^112 Regards, Dieter
