(4) 10-14 20-24 (5) 14-17 24-27
This time 24-20 would have lost, as Black would have replied (6) 17-13, 20-24; (7) 3-7, 12-8; (8) 15-11.
(6) 17-13 27-32
Avoiding 27-24 which would lose by (7) 3-7
(7) 13-9 32-27 (8) 9-14 27-24 (9) 14-18 24-27
Drawn. White has to watch 3-7 and to take care to play 24-20 at the right time so as to exchange 16-11 if 3-7 is played. At the same time he must beware of playing 24-20 when the Black Kings are on squares 15 and 5 or 15 and 13, as otherwise Black would reply 5-9, 20-24; 3-7, 12-8; 15-11.

GENERAL PRINCIPLES AND ILLUSTRATIVE GAMES
It is possible to apply general strategic principles to the game of Checkers, just as well as the game of Chess, even though there is not the scope in Checkers for strategic maneuvers on the grand scale on which they can be carried out in Chess.
Again it is naturally the principle of greatest mobility which should govern the plan of mobilization in any opening, and it is consequently more desirable to have the men work in the center of the board, than on the edge, where part of their range is cut off.
