A correction to Strickland’s "Kelso" Game.

Thanks to Martin Fierz's "CheckerBoard" program which made possible the recording of this game.

[Event ""] Ref.: Kelso Var. 1, diagram by Strickland, Page 104 "The British Draughts Player".

The position in the diagram is formed by:

10-15 21-17 9-13 25-21 11-16 24-19 15x24 28x19 8-11 17-14 16-20 29-25 4-8 22-18 6-9 25-22 11-16 22-17 13x22 26x17 – Red to move and draw. Solution given in "The British Draughts Player" is as follows:

An analysis corrects the given SOLUTION as follows: 2-6 30-26 (instead of 31-26,which is the second move of above solution. 30-26 now prevents 9-13 which would allow 14-9, 5-14, 18-2 or 13-22, both lose.) 6-10 32-28 8-11 28-24 3-8 26-22 1-6 17-13 10x26 31x22 7-10 22-17 10-14 17x1 9-14 18x9 5x14 19-15 11x18 1-6 18-22 6-10 14-18 23x14 22-26 14-9 8-11 10-7 26-31 9-6 11-15 7-11 28. 16-19 11x18 19x28 27-23 31-26 23-19 28-32 18-22 White Wins - HRG
