If your opponent offers you a draw, try to work out why he thinks he's worse off
I am acutely conscious, from vast experience in opens, that guys around, say 2100 or more can definitely play chess and that one often has to work very hard to beat them.
A good sacrifice is one that is not necessarily sound but leaves your opponent dazed and confused.
Unlike my esteemed colleague Garry Kasparov, I don't restrict the strength of opposition to Elo <2000, as fly-swatting makes poor spectator sport. (on simultaneous exhibitions)
