Hints if the original docu is unavailable

  • Rules are standard rules of Checker
  • Moves are done by entering start and target coordinates e.g. F2E1 or f2e1 also f2-e1
  • An invalid move results in +11^checker
  • Don’t worry enter GOTO or simply G to continue with a valid move.
  • If your opponent reaches the bottom line and gets a KING it is totally paralized and can’t move it anymore (Seems to be a bug)
  • So it’S hard not to be a winner.

Remember the focus is on TSQL support
