cwbowron in the house again. PSP Chess has been updated to v0.19. Changes:

possibly fixed weird illegal white rook move when it was black’s turn – please let me know if you see it (chess @ bowron.us)

clear tables option – debug tool

minimum delay – by request | if set, the computer will delay its move until this number of seconds has passed. Gives human players more time to think and not feel rushed by computer.
