Northern Michigan is my current home. I grew up near Detroit, and played chess as a junior. I attended Hope College and the University of Chicago, and lived and worked in Washington DC for 10 years.

I'm just getting back into chess, and enjoying as a way to find my way back.

   Feb-14-18 Larsen vs Joel Benjamin, 1987 (replies)
DrGridlock: <agb2002> writes: White can start an attack the black king with 45.Rxf7 (45.Ra8+ Kh7 46.Rd7 Rxg2+ 47.Kxg2 Qe2+ seems to win for Black) In the 45 Ra8+ sideline, after 45 Kh7, 46 Rf8 is an improvement for White. Komodo rates it as +1.8 for White. Enough for the win, but not ...

DrGridlock: ... Qh7 is crushing. Just not "as crushing" as Rxh6.
   Nov-14-17 L Schandorff vs T Willemze, 2016 (replies)
DrGridlock: Took me a while to identify that black's bishop on d8 was over-worked. I first looking for a way to jam White's queen into g7 and ways to gain tempos to do that. Next I noticed that Black's queen was unguarded, and that an uncovered attack on it by a knight check from d5 to f6 ...

DrGridlock: I too thought that Re3 would work. To those that write that Re3 picks up the exchange - it doesn't. After: Re3 Be4 Rd1 f5 f3 f4 White doesn't even get the exchange out of the Re3 line.
   Sep-19-17 C F Morris vs D Garcia Ilundain, 1997 (replies)
DrGridlock: Oddest strategic idea ever: of White's 43 moves, 11 of them involve his king's rook. Investing 1/4 of his tempos in geting a piece trapped on the h-file is definitely a "don't try this at home" one for the kids!
   Aug-29-17 E van den Doel vs Nijboer, 1997 (replies)
DrGridlock: 34 ... Rf2 is the most direct win, but 34 ... d4 or 34 ... e2 are also winning. Not sure why I spent so much time looking at getting e2 to work instead of Rf2, but wins e2 does.
   Aug-22-17 V Bui vs H Frey Perez, 2002 (replies)
DrGridlock: White's (overloaded) rook on b1 protects the queen on b4, and against mate on c1. 32 ... Rc1 "Give me your queen, please!"
   Aug-16-17 de Firmian vs Huebner, 1995 (replies)
DrGridlock: I wanted to go quite directly for mate on g7. Seeing that 3 of black's pieces were tied down to defending f6, I thought that removing 1 (or 2) of them might work. However, in the line 23 Bxd7 Qxd7 24 g3 Nick DeFirmian - Robert Huebner [DIAGRAM] Black is saved by the rather ...
   Aug-14-17 N Zwirs vs P V Nandhidhaa, 2016 (replies)
DrGridlock: Rather nuanced for a Monday puzzle. Both Rxg5 and Ng6 lead to mate (though Ng6 is the quickest mate). I went for the Rxg5 line, but this leads to mate only after 23 Nd7. The branch I analyzed instead was 23 Ng4. This does NOT lead to mate, because black can throw a blockade on ...
   Aug-10-17 Caruana vs M Vachier-Lagrave, 2017
DrGridlock: Much discussion during the game of White's opening innovation 10 Qd3, and whether black can take the "poisoned pawn" on b2: [DIAGRAM] While I get the "psychology" which led MVL to play safely with 10 ... Nbd7 (not wanting to jump into another player's home preparation), it's hard
