Feb-12-06		CeeFoR: That's got to hurt

Jul-29-19		fredthebear: A poke in the Queen's eye definitely hurts!!

Jul-29-19		OhioChessFan: "Koptev Audience"

Jul-30-19		Cheapo by the Dozen: Feels like a fun 19th Century game. :)

Jul-30-19		An Englishman: Good Evening: Could have sworn that White had the edge after 14.Bg5; underestimated the counterattack beginning with 14...b6! 15.Qd3 might prove a critical error--perhaps 15.Qf4 improves?

Jul-30-19		Pyrandus: "Critical error"? I like this expression.

Jul-30-19		OhioChessFan: <Pyrandus>, so do I. I didn't lose my last game due to a stupid mistake. It was a critical error.

Jul-30-19		goodevans: <An Englishman> I agree. To my amateur eyes white looked better after <14.Bg5> but the way the game panned out showed how much attacking potential was in black's position and how much weakness was in white's. After your suggestion <15.Qf4>, <15...Bc5+ 16.Kh1 Qh5> brings about a position similar to the game. click for larger view White has saved a tempo compared with the game continuation but it's of little good to him as there's simply nothing he can do to stop the same devastating <17...Be3!>. It seems it's imperative on move 15 to stop <...Bc5> being made with either Q pin or check. The B retreat <15.Be3> would achieve that but feels very passive. Maybe sac'ing the exchange with <15.Rxf8+> is best.

Jul-30-19		catlover: What a fun game! Was Paul Morphy playing black? I wonder if 16. Bf4 would have improved White's chances.

Jul-30-19		Autoreparaturwerkbau: White should play simple <16.Bf4> and all is well.

Jul-30-19		goodevans: <catlover>, <Autoreparaturwerkbau> 16.Bf4 is an improvement but is still in black's favour. If you're using an engine try increasing the depth of the search. White would be better addressing his problems a move earlier.

Jul-30-19		RandomVisitor: If white wants to play the 5.Ng5?! line here he should know that 6.Qxd4 is almost necessary after 5...Ne5. Why play a line so early in the opening that gives so much to your opponent?

Jul-30-19		gezafan: Isn't Estrin supposed to be an expert in the Two Knights? It just shows how even specialists in an opening can be surprised. Chess is a complicated game.

Jul-30-19		keypusher: < gezafan: Isn't Estrin supposed to be an expert in the Two Knights? It just shows how even specialists in an opening can be surprised. Chess is a complicated game.> I think I have a warped perspective on Estrin, because the (few) games of his I know generally feature him losing in his favorite open games. Like Estrin vs Berliner, 1965 and Estrin vs V Palciauskas, 1978.

Jul-31-19		An Englishman: Good Evening: <goodevans>, you found a good line, but doesn't White's saved tempo allow him to play 17.Qg3 in your position? Now White's Bishop can guard the e3 square while the Queen can protect h2.

Jul-31-19		goodevans: <An Englishman> 17.Qg3 would exactly replicate the position in the game after white's 17th move.
