I’ve been nagged by my lousy tactics by a friend in FICS so I spent some days at chess.ermrald.net trying to improve. Here’s a position from recent blitz game against 1458 player where he had major tactical oversight with ..Qb6. I am sure the hours spent on tactics helped here to see the oversight. Actually I saw the possibility even before black move and kept summoning (shouting aloud) the possibility to play it.
White to move.
