You flopped a flush draw — what now?

With four to a flush on the flop you hold nine outs. You hit on the turn about 19.1% of the time and by the river about 34.97% — roughly one in three. If the turn bricks, the last card is worth only 19.6%. That gap is exactly why semi-bluffing a draw on the flop is far more profitable than firing the same draw on the turn.

Why a pocket pair is worth more than it looks

A pocket pair flops a set 11.8% of the time. That sounds small, but a set is a disguised hand that extracts value from top pair, and the 1-in-8.5 ratio is the basis of the classic rule of thumb: call pre-flop only when stacks are deep enough to win roughly ten times your investment on the hands you do hit.
