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.

   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 DeFirmian 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
   Jul-11-17 D Anic vs Degraeve, 1997 (replies)
DrGridlock: <Pasker> Agreed that e6+ is the key move in the combination. The deeper key is understanding that the "value" in e6+ is NOT in the discovered check by the bishop on c3 (since it can be taken easily enough by the b-pawn), but IS to cover the f7 square and cut off the black ...

DrGridlock: Get that pesky White King from standing in front of the black pawns with ... Bg4+, and in the words of Queen, it's "Don't Stop Me Now"
   Feb-27-17 E Horn vs K Cedikova, 2007 (replies)
DrGridlock: The White King's journey in this game is to be studied: K-e2-f1-g2-f1-e1-d1-d2-c3-b4-a3-b2-a3-b4-mate Kids, don't try this at home!
   Feb-15-17 Smyslov vs C Kottnauer, 1946
DrGridlock: After 33 Rxd6, Black to move Vasily Smyslov - Cenek Kottnauer [DIAGRAM] To take or not to take on e4? Rxe4 - good (position is level). Bxe4 - bad (black's position is lost). Game appears as game 53 in Daniel King's "The Closed Sicilian." Hardly a model of opening play ...
   Feb-02-17 P Danenhower vs Spassky, 1971 (replies)
DrGridlock: < swclark25: <agb2002 This suggests 27... Ne3+: A) 28.Nxe3 Qxg3+ 29.Kf1 Bh3+ A.1) 30.Rxh3 Qg1#.> I also went with these moves thru 29)..Bh3+. I can't see checkmate with 30)..Qg1+ since 31)Qxg1. Looks like 30)..Qxh3+ is best and should be winning. Am I missing ...
   Jan-09-17 Chandler vs O I Barkan, 1975 (replies)
DrGridlock: <stst> "Also, 25.Nd8/d6 dis+ by Q will snatch Black's Q, Black is tortured." After: 25 Nd8+ Nxc4 26 Nxb7 Bxb7 Hasn't black just lost a knight? Seems the "tortured" has become the "torturer."
