Part: Part Six - Betting After the Flop

Betting for protection

You opened and the big blind called. Flop Q♥ J♥ 4♣ - you have an overpair (kings), but the board is loaded with draws. He checks.

An overpair on a very wet board, he checks. Best?

WhyCount the ways this board beats you by the river: any two hearts makes a flush, and hands like KT, T9, and AK are all one card away from a straight. Your kings are ahead right now but fragile, so a big bet forces every one of those draws to pay a bad price to keep going, while worse pairs still call. Check, and you hand a free card to the exact hands built to outrun you.
What happensYou bet 1,000; the big blind calls. Pot: 3,300 (16.5 BB). Notice the call keeps his draws in the hand paying full price - that's the plan working, not failing.

Turn 2♠ - a blank, but the flush and straight draws are still out there. He checks.

Draws remain live and he checks. Best?

WhyThe deuce changed nothing - every draw that called the flop is still live and still behind. Keep the pressure on so the flush and straight cards stay expensive and worse pairs keep contributing; slowing down here just offers a free river to the hands you're trying to beat.
What happensYou bet 2,400 and he folds his draw. Winning it now is the whole point - far better than letting a river heart show up and take the pot from you.
Protection and value aren't separate goals here. You bet both streets to make the flushes and straights pay while worse pairs called, folding out exactly the hands that would have drawn out on a free card.

On a wet board, charging the draws IS the value bet - a vulnerable made hand bets big to make every drawing hand pay a bad price rather than see cards for free.
