It’s getting harder and harder to come up with a truly original idea for a chess book. But a few recent works break new ground.

“Invisible Chess Moves” ($23.95, New In Chess) by Emmanuel Neiman and Yochanan Afek explores why you can’t see good moves that are staring you in the face.

For example, we have blind spots when it comes to spotting the right move — either for us or for our opponent — when it is a retreat by a knight or bishop, a “desperado” lunge by a doomed piece, or the in-between move called zwischenzug. There are 53 test positions to see how good you are at seeing the invisible.

Another original work is “The Greatest Ever Chess Endgames” ($26.95, Everyman Chess) by Steve Giddins. He chooses and analyzes well some 50 endings that changed endgame theory or chess history, or simply stand out for their beauty or teaching value.

And “The Kaufman Repertoire for Black & White” ($29.95, New In Chess) has a unique physical feature. Larry Kaufman offers 266 pages of analysis to show how to play openings as White. Then turn the book upside down and there are 229 pages of recommended lines for Black.

In this week’s game, White resigns in view of 29 . . . Rxc2! followed by 30 . . . Bxe4 or 30 . . . Nxe4.
