The WHITE DOCTOR

11-16, 22-18, 10-14, 25-22, 8-11, 
24-20, 16-19, 23-16, 14-23, 26-19

Another extremely complicated, man-down opening. Here the first player MUST go a man down with the 16-19 exchange or he will lose as a result of a fatal single corner cramp. Instead, the second player (white) now has a cramp which will eventually force him to give back a checker.
