Key Krackers, the legendary Chess Life column, is now on the web. The diagrams are twice as big as they were in Chess Life, so you no longer have the excuse that you could find the mate, if only you could see the position. So get out your brain, (not your computer's) and solve, solve, solve! In fact, if you're the first person to submit twelve correct answers to David.L Brown, you'll win a free, autographed copy of U.S. Problem Anthology, a problem collection compiled by Edgar Holladay.
New Solvers: In Directmates (commonly known as Mate in Two, Three, etc.) White always moves first. Only the key-move defeats every black defense in the stipulated number of moves. You should list only these keys, no variations!
In Helpmates, Black always moves first, and both sides cooperate or "help" to mate the Black King. All moves must be legal. Full length solution(s) to helpmates must always be given by the solver. The best way to understand helpmates is to study past issues with solutions.
Long-time solvers: Please note that these numbers correspond to 2630-2641 in Brown's ouevre. Click here for Chess Life's April Solutions. May Solutions will appear with the web publication of the July Chess Life. (c. July 10)
