Game Collection: They were surprised

May-08-12  Notatiger: Just saw the Jan-2012 comments, and took a fresh look at Chessgames' own notes in the panel beneath the game.

Here is some clarification:

Chessgames' characterization of 27...f3 as a "Q-sac" is wrong. The move wasn't a sac; it was a blunder. I (Jon Jacobs) simply overlooked 28.Rxg7+. Instead of 27....f3, Black would win simply after 27...Qc8+ followed by ...f3.

After the inferior 27...f3, White missed a forced win. Instead of checking on g7 the second time (i.e., on move 30), White would win with 30.Qb1!, threatening both Qb3+ and Qb7. After 30...Qc1+; 31.Kh4 Nd4; 32.Qb7 Nf5+ 33.Kh3! Black is out of checks and must concede the exchange of Queens, going into an ending 3 pawns down.

I published this game with notes in both Chess Life (April 2005 I think) and in an obscure correspondence chess magazine back in the mid-1970s. As I wrote then: "Exhausted by his long defense, White is happy to grab what looks like a forced draw by repetition (via 30.Rxg7+). He should have heeded Tartakower's advice: When you see a good move, wait! Look for a better one!"

Also note this very unusual feature: Black can grab the g7 rook the second time but not the first time... only because 29.Rxh7+ opened up the h-file for a Black mating attack!

  Phony Benoni: According to the tournament book, a few more anticlimactic moves were made:

<36.Rxe2 Rf3+ 37.Kg2 Rxd3 38.h4 Rxa3>

White refused to give up before his DIRP was destroyed.
