I'm a maniac on the flop with these draws, but I slow down on the turn when I miss, for one simple reason... we have half the equity we had on the flop.

At the flop, when we get raised, there's $1.40 of dead money before we act. That dead money makes shoving profitable, we don't need 50% equity. And if we have any fold equity (he might bluff raise flop) this just increases our overall winrate. But we don't need him to have bluffs, because if we have 45% equity, and $1.40 dead money, well you do the maths. If we're called 100%, we still win money. If villain folds, we just won a decent pot with nine high.

Shoving flop is beautiful because we like villain calling or folding. Both make us money.
