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.

DrGridlock: Not really a "mate in 2" As < saturn2 > points out: Black wins 48...Ne2+ 49. Kxh3 Qg3 mate 49. Kg2 Qg3+ 50. Kh1 Nf2+ 51. Qxf2 Qxf2 queen 49. Kh1 Ng3 quuen fork It's the lines where black does not take on h3 that get "tricky" to verify. Black wins massive material, ...

DrGridlock: <1g1yy: I started off immediately with qh5, and although it does allow black one full tempo, the end result is the same. I see the Rook Sac is more forceful but mate is mate.> Can you give us your line to mate after: 21 Qh5 fxg6 The entire point of the puzzle is that ...
   May-18-21 L Christiansen vs Shirov, 1991 (replies)
DrGridlock: White missed a forced win at move 34. (Hat tip to Andrew Soltis who includes this in "The Inner Game of Chess"). White would like the queen check at f8 to be more productive, but after: 34 Qf8+ Kg5 35 h4+ Qxh4+ stops white's attack and launches black's. It's not easy to ...

DrGridlock: I misread the position, and thought it was White to play ... in which case Rc7 is pretty devastating.
   May-17-21 Nakamura vs Kudrin, 2004
DrGridlock: Engines have gotten better! Nakamura has stated that he relied on Rybka analysis in preparing his opening play for this game - with an eval of approximately +3 for White after 17 Bg5. As the gameplay demonstrates, this is NOT a won position for White. Running the same position ...

DrGridlock: Rxf3 -- mate in 3 Bh3 -- mate in 6 You choose which is the "correct" solution!
   Apr-05-21 Liberzon vs N Giffard, 1980 (replies)
DrGridlock: So until my morning coffee kicked in ... Trying to get the queen to the 2nd rate to smother White's king with a mate. I notice that Rxe2 is a discovered check, which might allow the queen to slide into f2 after Kf1. But then I notice that White's queen on a3 can take black's ...
   Mar-22-21 Pelletier vs Matamoros Franco, 2012 (replies)
DrGridlock: Interesting that in the queen and rook (!) endgame the key for black at move 36: Yannick Pelletier - Carlos S Matamoros Franco 1-0 9.28, Chess Olympiad 2012 [DIAGRAM] is to know that a rook exchange at b7 greatly advantages white. The white queen will clear the way for the ...
   Mar-03-21 Tal vs J Miller, 1988 (replies)
DrGridlock: I'm surprised how deep the game goes with an advantage for Black. Fat Fritz scores it -.81 for black after 19 ... Qc6 (instead of the game continuation 19 ... Qd6): Mikhail Tal - Jack Miller 1-0 0.0, Simul Anaheim, CA USA 1988 [DIAGRAM] It's hard to play sharp positions against ...
   Feb-02-21 M Keller vs W Bogatzki, 1976 (replies)
DrGridlock: < the puzzle solution is NOT a thumping win in the way we usually expect; e.g., the engine rates the position after the sac at +1.06.> That was the hardest part of the puzzle. I saw very quickly that: (i) Bxf7 was a nice entry for the bishop (ii) The bishop was poisoned, ...
