In Round 4, Tim Ailes and I reached a typical Benko Gambit position.
Bill Brock-Tim Ailes
Black to play after 21.Ne2
As usual, all Black's pieces are pressing (or, in the case of the Nd7, about to press) the a- and b-pawns. Black has to decide how to handle the threat of Nxd4. Doesn't 21...Rb4 look natural?
Bill Brock-Aun Thant Zin
Doubtless encouraged by my toothless opening, Black played 27...Qb4. How would you respond? (And how do you think I responded? There's more than one good move here: I saw a "hard" one and overlooked an "easy" one that my good-natured opponent pointed out to me immediately after the game.)
I'm not trying to embarrass my creative opponents (who, aside from these lapses, played extremely well) or flagellate myself for our collective blunders. What can we do to blunder less often?
