Alapin-Levitsky, St.Petersburg, 1911; White
to play
The most plausible reason for Alapin not having seen the winning combination [it's mate in 4 -- DR] was that he did not expect there to be one. The reader, who faces no such uncertainty, should have little trouble in discovering what was overlooked." Mullen/MossThat realisation that you have to look seems to be at least as important as any calculative ability. I find I can normally guess the key moves of 'Find the Winning Continuation' positions in the British Chess Magazine at least half the time after a short glance, yet I can't see all the tactical points of the position even if I sit there for an hour. What you really need for a proper test of your decision making is to have... Well, what might you have? Say, a PGN database of 1001 Winning Chess Sacrifices and Combinations but with a random 500 of the positions doctored so that the tactics don't actually work. I don't fancy the task of doctoring very much, but that would be a very valuable resource for coaches. Or you could have a book, with six positions on a page, and in two there's a winning tactic, in three there's nothing happening yet, and in one there's a tempting possibility which drops you into a trap. It's obviously harder work than collecting pretty finishes, but I am convinced it would be better training [Postscript: I became so convinced of my argument that I'm now writing just such a book...]. The best book I know which leans in this direction are Chris Ward's It's Your Move/Chess Choice Challenge, where he uses amusing multiple-choice questions. I think they're very good -- although with just one position per page they had better be! The positions are quite variable in 'level', I think, and even these books still have too many positions with a 'point', so you usually know that if you do see a point it's probably one the author expects you to find. [There's an analogy from natural history: birds trained to look for one type of prey all the time do very well in tests; if they have to look for two or three types at once (which may or may not be there) then their performance plummets.]
"I have heard from students about instructors teaching players rated 1200-1300 Philidor and Lucena positions. Yet I know someone who lost an easily drawable Philidor position because he did not know the technique and never heard of it. My point? That player was me: I had been playing tournament chess for 5½ years and my USCF rating was about 2100! Sure, if I had known the technique I would not have lost, but the point is that I got to 2100 without ever even hearing about the Philidor draw because such specific knowledge is only marginally useful (not useless!) and I was pretty good at each of the Big Five."
I don't think this is entirely fair. I can think of only two games in the last 20 years where I've had to play a pure King and Pawn endgame. But the ideas I learned studying K+P endgames (opposition, squeezing, zugzwang, in the square...) I've probably used in any number of games, and the threat to swap off into a winning K+P ending occurs constantly. The same may be true for the Philidor and Lucena positions: I've had Philidor maybe twice and Lucena twice, but the ideas crop up over and over again.
pThe theory is easy enough to get across, but there is still a requirement to come up with a similar mix of examples as test material: some requiring exact analysis of forcing lines, some where you have a strong positional move to make, and others which are examples of normal play, where there is nothing critical to do and any decent move would strengthen your position. I very much liked the 'How Good Is Your Chess' approach in the Mednis and Crouch book 'Rate your Endgame', but it is pretty stretching for most players (as is the study-based Livshitz/Speelman 'Test your Endgame Play'). I think I'd sooner see a bunch of positions drawn from practical play, maybe from Capablanca's games, where accuracy and sense are required without bewilderingly deep analysis or fantastic finesses. It wouldn't be too hard to whizz through Chernev's book and pick out a few positions from each game where the move chosen has some modest instructional value.
