The Checker Maven

Holiday Coffee and Cake

It's the holiday season, which means family, friends, and feasting. So, we at The Checker Maven thought, why not treat our readers to more coffee and cake?

Our old friend Brian Hinkle sent us a composition of his own that he thought would make a great "coffee and cake" problem, and we heartily agree. It's a 3x3 twin with, as Brian points out, the unique feature that no matter who plays, White wins.

So, in between courses at your holiday dinner, or maybe after dinner with a second helping of coffee and cake, you might want to try this one out. We think it's easier when Black is to play, but you'll have to decide that for yourself.

Solution

With Black to Play the solution is relatively straightforward.

 1 17-21

Other possibilities:

12-16 24-20 (not 24-19)16-19 26-22 17x26 30x16 White Wins.

17-22 26x17 13x22 24-19 White Wins.

 1 ... 24-19 2 13-17 19-15 3 12-16 15-10 4 16-20 10-7 5 20-24 7-2 6 24-27 2-6 7 27-31

Or 27-32 6-9 32-27 9-13 27-31 13x22 White Wins.

 7 ... 6-9 8 31x22 9-13

White Wins.

With White to Play, the solution is longer and the White win requires several star moves at the outset.

 1 ... 26-23* 2 17-22 23-19* 3 13-17 24-20* 4 17-21 19-15

Or 20-16.

But not 23-18.

 16 10-14 20-16 17 14-10 16-11 18 10-14 11-7 19 14-10 7-2 20 10-14 2-7 21 14-9 7-10 22 9-5 10-14 23 5-1 14-9 24 1-5 22-17 25 5x14 17x10 26 21-25 10-15 27 25-30 19-16 28 12x19 15x24 29 30-26 24-27
