INSTRUCTIONS
******** Chessnut (Version 1) Colour (low res) only ******** The program: Was written in 68000 assembly language using Fast Basic's in line assembler It understands all the rules of chess but note it can't underpromote itself, or recognise a draw from inadequate material Most of the usual facilities are available (except clocks) A move is made by entering the correct algebraic notation (eg "E2-E4") You can't move a piece using the mouse An illegal move is not permitted ******** Set up mode: Enter colour,piece, algebraic position For example: "WQF3" puts a white queen on F3 "BPM+E6" puts a moved black pawn on E6 " C5" erases C5 square Pressing "M" after 'piece' means it will be seen as having moved Pressing space will erase the contents of the square ******** Levels: Determines width of search but not depth which is always 5 ply where possible Level 9 searches all checks to 5 ply ******** Opening Book: A selection of popular openings plus a few unusual choices A book move will be played instantly regardless of level ******** Analysis: Lets you see what the ST is 'thinking' All moves being examined at 5 ply will be shown and not just the 'best so far' ******** The display: You can choose between 2/3 dimensional boards and change the board and piece colours. You can also select a shaded board The viewing angle can be changed to: 2 positions in 2 dimensional mode 4 positions in 3 dimensional mode (an arrow shows the direction that white is playing) The Atari logo indicates that the ST is 'thinking' The menu bar is hidden until the mouse cursor reaches the top of the screen ******** The Chess algorithm: A simple fixed ply minimax program, all moves within width (defined by Level) are examined to a depth of 3 ply The 5 'best moves' are then examined to a depth of 5 ply The efficacy of the evaluation function hasn't really been thoroughly tested but most 'poor' moves are due to limited search width ******** Gary Franklin, 51,St Marks Road, Canvey Island, Essex
