For human users of my chess program Queen, there is now a new version that displays the moves in standard notation, for example, Nf3 instead of g1f3. The moves of the game are now displayed in a window with a vertical scrollbar, so that all moves of a long game can in principle be seen. I also fixed an error that sometimes occurred when the user took moves back. I did not change anything in the engine itself, so this new version plays as strong (or as weak) as the previous one in computer chess tournaments.
I hope I did not spoil the program in other points; it had been a long time since I worked on Queen, so changing the program was not without risks. If you find anything incorrect or otherwise very undesirable in it, please let me know.
Best wishes,
