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.

   Jun-22-20 E Pettersson vs Stahlberg, 1935 (replies)
DrGridlock: Black is already two pawns up - but after the (very temporary) rook sac (Rb1+) and knight fork (Nxc3 / Nxe2) he's up 3 pawns with just knights on the board. Kind of a positional parlay, but a decisive one nonetheless.

DrGridlock: I tried to apply the first rule of Monday puzzles and sac the queen, but the darn knight was in the way Light bulb !!
   Jun-08-20 D Byrne vs W G Addison, 1969 (replies)
DrGridlock: <petemccabe: It is not particularly hard to find this move that wins a pawn (if properly declined).> At first I thought black could limit the material loss to 1 pawn. However, looking through Fat Fritz's best line for moves other than bxc6, you'll notice that White's knight

DrGridlock: <I asked a number of non chess playing friends who are sports lovers how they think this should be resolved.> Did your non chess playing friends know what rule MLB uses to resolve a game that is interrupted by rain when less than half it has been played?
   Mar-22-20 Caruana vs I Nepomniachtchi, 2020
DrGridlock: White to play at move 31 is the key moment in this game. As others have pointed out, 31 Qd4 (not played) is the key point in the game. Queen, minor piece and pawn endings are really hard to play, because the queens can fly around the board and change things so quickly. White's ...
   Mar-20-20 Ding Liren vs Caruana, 2020 (replies)
DrGridlock: <offramp> The 21 Re5 line (not taken) is certainly one of the key analysis points of the game. Fat Fritz likes 24 Qxf4 as an alternative for white in your variation, with a better eval for white (by about a half pawn over your line). This line is very sharp - with the ...
   Feb-24-20 Szabo vs B Sooky, 1946 (replies)
DrGridlock: It's a fairly direct puzzle to solve. No mating threats, and the only black piece that has moved is the knight sitting on g4. It's protected by black's c8 bishop. Now if only there were a way to break that protection and to do it with a tempo to hang the knight out to dry ...
   Feb-17-20 Kosteniuk vs Ju Wenjun, 2020
DrGridlock: <doubled her rooks on the e-file> Fat-fritz prefers exchanging rooks on d8 at move 15, then occupying the d-file with white's remaining rook: 73: Alexandra Kosteniuk - Ju Wenjun 0-1, Cairns Cup St Louis, MO USA 2020 [DIAGRAM] It's interesting here that the rook attacks ...
   Feb-10-20 R Swinkels vs C Bauer, 2007 (replies)
DrGridlock: Took me a little too long to solve (though I eventually did). My thinking was - Black's queen is attacked, and "en pris" - so I either need to move the queen or give a check. I kept trying to find a way to move the queen to the a-file and dance around White's b-pawn to deliver a ...
   Feb-03-20 G O'Toole vs R Haria, 2009 (replies)
DrGridlock: My thinking was: The bishop sac on g6 looks inviting. Black's pieces (rooks, queen, bishop) are ALL locked off from moving anywhere to the f, g or h files. If black takes the bishop (fxg6), the check on f7 looks somewhat deadly (because there is no one left to come to the ...
