   Apr-19-19 Nimzovich-Larsen Attack (A01) (replies)
bobbyperezchess: 1.b3 e5 This move is the "most common." But this is not scary at all. 2.Bb2 Nc6 3.e3 d5 4.Bb5 Bd6 (4...f6 5.d4 e4 6.Be2 and it seems it is equal. White will obtain the f4-square and thus he/she will get pressure against the black's center...) 5.f4 f6! The most challenging ...
   Apr-19-19 Nimzowitsch vs Yates, 1928 (replies)
bobbyperezchess: 44...a5?? just draws. Instead, 44...Qg1+! 45.Kf3 Qf1+! 46.Kg4 Qe2+ 47.Kxh4 (47.Qf3 loses to 47...f5+ -+) g5 48.Kg3 Bf4+, winning the queen and the game.
   Nov-07-18 Y Hou vs Naiditsch, 2009
bobbyperezchess: A beautiful fork on g3! Hou Yifan may have missed 15...Bxb3 ∓ / -+. I think she also thought about 14...Nf4. 14.Kh2 may have been better, although after 15...Nf4! black has the initiative. Black also wins a pawn on d3! 14.Re1! Nf4! 15.Qf1 defends d3, though white's ...
   May-24-18 Capablanca vs Marshall, 1918 (replies)
bobbyperezchess: 11...Nf6?! is risky. Better moves are 11...c6! and the calmer 11...Bb7!? . However, those moves aren't still known in that era! 11...c6 became the main line of the Marshall after Spassky popularized the ...c6 Marshall and used it as a drawing weapon, while the ...

bobbyperezchess: Who's Carlsen's Challenger for the next World Championship Match?
   May-24-18 Team White vs Team Black, 2017 (replies)
bobbyperezchess: 7...d6! is better than 7...Qe8?!. 7...Qe8?! is inaccurate. It should be 7...d6 first with the idea of ...Nd4 and ...Bg4, e.g. 8.b4!? Bb6!? (8...Bxb4?! 9.c3 followed by d4; 8...Nxb4!? 9.c3 Bg4! 10.Qa4 Nc6 with compensation for lost castling rights.) 9.c3 (9.a3 concedes d4) ...
   May-22-18 D Mayers vs Fischer, 1953 (replies)
bobbyperezchess: I don't want King's Gambit Accepted. Decline it with 2...Bc5!?
   May-22-18 S Williams vs The World, 2013 (replies)
bobbyperezchess: 5.g4????? (question, not mark) Better is the book move 5.Na3.
   May-22-18 The World vs Karpov, 1996 (replies)
bobbyperezchess: 14.Qc2!? raises a question to black if he would play ...Bxf3, ...c5 or something other than these two options. 14...Bxf3?! is not so helpful for black because it opens the g-file for white, and because of that, an attack is possible for white. 14...c5 is better, and after ...
   May-22-18 AlphaZero vs Stockfish, 2017 (replies)
bobbyperezchess: I don't like the move Stockfish played on its 11th move which is 11...Bf6?!, since it denies control of the weak square d6, which AlphaZero immediately conquers with 12.Nd6! . But still, Van Arkel played this positional error in his game against Roobol. Roobol played ...
