Sometimes it can be good to take some more time in blitz and not play auto-pilot - impulsive fast. After black's 17...Be2 the first impulse was to play 18.Rfe1 but then after 18...Bd3 I would lose the pawn on e4 or the exchange. With the black king on f8 it was tempting to play Qa3+ to possibly improve the position of the white queen. Only then I noticed that black could go wrong because of bankrank weaknesses. Was it bad that I hoped for that ? Or should "the better player" ("Good players are always lucky" - Capablanca) try to always challenge the opponent by playing the most annoying moves to deal with ?
After black's 19...Ra8?? I saw suddenly ghosts thinking that after 20.Qxa8+! black could play Nb6 to c8, and too quickly decided for 20.Rxb6
