My name is David Goldfarb; I live in Houston, TX. I haven't played any tournament chess in a while, although I check the problems here every day and am a Life Member of the USCF. My rating is about 1800. My favorite player is David Bronstein, though I couldn't play like him in a million years....

goldfarbdj: My first thought was 33. ... Nh3+ 34. Kh1 Nf2+ 35. Rxf2 Qxc1+ winning the exchange. Then I looked a little deeper and noticed that 34. Ng3+ wins queen for knight.

goldfarbdj: I tried Ne8+ first, with similar continuations if the rook takes. But if the queen takes, too many squares are now guarded. Then I realized that the other knight check doesn't allow queen takes.

goldfarbdj: I got Rc6+, but I missed Qa6 mate. I had Qxc6 Ka7 (Ka5 66. Qb5#) 66. Qa6+ Kb8 67. Qa8 mate. Oh, well.
   Sep-08-18 Topalov vs Ivanchuk, 1999 (replies)
goldfarbdj: When I was first looking at this, I hallucinated the existence of a black bishop on f6, which makes the puzzle Monday-level: 18 ... Nf3+, and if the king makes its only legal move to f1, Bh3 is mate; but taking the knight allows Bxc3+ winning the queen. Then I realized that the ...

goldfarbdj: I spent a bunch of time trying to find a good discovered check after Nd3+ Kf1. Finally I realized that Nc2 was the correct check.
   Apr-24-18 US Championship (2018) (replies)
goldfarbdj: I would so love Shankland to win this tournament. I can already say, "I've won a game at tournament time controls against a player who holds the GM title." Then I could amend it to "...who has won the United States Chess Championship." (Okay, yeah, at the time he was 13 years old
   Mar-08-18 Neo Zhu vs Shabalov, 2017 (replies)
goldfarbdj: Somehow I thought the piece on g7 was a pawn rather than a rook, and I had no luck finding anything.
   Feb-06-18 Joel Benjamin vs Mephisto, 1987 (replies)
goldfarbdj: Took me a little bit to find the right answer. What a pretty final mating net! The bishop protects the rook right *through* the king.
   Jan-25-18 Fanghui Sun vs Ju Wenjun, 2017 (replies)
goldfarbdj: Nxd4 seemed pretty obvious, but I thought that 21. Qxb7 would be met with 21. ... Nxf3+ 22. Qxf3 Rxc1, when 23 Rxd7 is met by Rxe1 mate. Is there a hole in this line that I'm not seeing?
   Dec-29-17 C Garcia Palermo vs C Herrera, 2001 (replies)
goldfarbdj: <bcokugras>: 35. Rg3+ and mate next move; White will play one of Qh4, Qxf5, or Qe7, depending on where Black's king goes.
