Here at The Checker Maven, we've long felt that we've "hit the jackpot" with our more than 2,500 weekly readers and the acceptance and welcome our webzine has received in its first year of publication.

17-14a, 4-8b, 14-10, 8-11, 10-6, 3-8, 6-2, 8-12, 2-7, 11-16, 7-11c, 16-20, 11-15, 20-24, 15-11d, 23-27 (24-28, 11-15), 19-16!, 12-19, 11-16, 19-23, 16-19e, White wins i.
a--- If 17-13, 3-7, 13-9, 7-10, 9-6, 10-14 etc. Draws.
b---If 3-7, 19-16, 4-8, 16-12, etc. White wins.
c---If 7-10, 23-26, etc. Draws.
d---If 15-18, 23-27, etc. Draws. The finish is by H. Tonkin.
e---Jack Botte, the New Jersey Match Champion, hails from Jersey City and frequently enters (and wins) New York "knockout" Tourneys. This ending is a good lesson in timing and economy of motion. Frequently one wasted move will throw away a well-earned win or draw.
