In sit-n-go heads up play, just like in any other, position is utmost important. If you’re the dealer, you have to raise on any decent hand you have. If on the flop the big blind checks, raise him as the check is the sign of a weak hand. If you are the big blind, check on every decent hand except when dealt with a strong hand. When the big blind raises in heads up, it means that he has a good hand.
