This one was a real bugger. It's the classic Psion Chess game, with actual chess pieces on an actual (or rather, virtual) board! Only problem - ZX Emulator doesn't show the bottom two input lines, because I stretched Wilf's routine to give 26 display rows... 24 for the board, and 2 for the input lines. So you have to key your moves in blind... not too much of a handicap, if you've played the original. To exit, press DELETE (shift 0) when it's your turn, followed by STOP (shift A) then ENTER. btw - to get out of Wilf's high-res mode from immediate mode you can (almost) always get out with PAUSE 0.
