Here’s what I’d do with a programmable chessboard 03/01/2017

Here’s what I’d do with a programmable chessboard, like the DGT or the SquareOff: It reads in a gamescore, compares your moves to the movdarth-vader-vs-chess-pieceses in the scoresheet, and if not a match, it replaces your move with the correct one.

In other words, that an automated version of the Purdy method for practicing chess the right way. (Play through a game, covering the winner’s moves and guessing as you go — I talk about this very often.)

For as long as I’ve practiced in this fashion, the practice was its own reward. But for this idea to work, people would want their Solitaire Chess scoring (Horowitz did that first in Chess Life, now Pandolfini does it), or grading by the Toga engine (from the Guess the Move feature at

Chess teachers would get good use from this. They could assemble groups of games to demonstrate a pattern (or a useless opening) or model player.

In the mid-’70s, the mechanical device for this kind of practice was test marketed (they called it CyberChess, though there was nothing cyber about it). At each turn, six candidate moves were presented, and the user moved sliding panels to get a score from +3 to -3 (coincidentally, that’s the range the Toga implements). It was a great idea — because it helped chessplayers study the right way — but RRS said the games selected for version 1.0 were all wrong. RRS would’ve installed his Blue Knights collection, right?

Whether you perform the guess-a-master’s-moves exercise online or in a box, or do it the old-fashioned way with a book plus a 2×3 card, it can’t be beat. With practice, you string together enough correct guesses to put you in the master’s league.

I used to think the most fun about this practice was when I guessed a better move than the master actually played (the annotations say when this happens), but nowadays I love this: When you’re playing a hard game, sometimes you make your move with a mental shrug while thinking: “OK, fine, I cannot be sure how this move will work out, but it was the best I muster at the moment”. When you’re guessing a game, and you guess a move with that uncertain feeling, sometimes it’s the right guess, and you feel like you’re sharing the feelings of a master, as well as the thinking.
