Part: Part Six - Betting After the Flop

You opened, c-bet a Q♦ 7♣ 3♠ flop with A♥K♥, and the big blind called. Turn 2♥ - you pick up a flush draw to go with two overcards. He checks.

You have overcards plus a flush draw and the betting lead. Best?

WhyThis turn hands you a flush draw on top of two overcards, so you're never barreling pure air - you have real equity plus a story that still holds from the flop. Betting pressures the medium hands that called the flop and sets up a credible river bluff if you brick. This is aggression backed by cards, not just nerve.
What happensYou bet 1,800; he calls. Pot: 6,600 (33 BB). His call keeps a range full of medium pairs and draws in front of you - and you've still got a flush draw and a story to fire the river.

River K♠ - you actually pair, but consider the bluff line: this is a card that completes a story of strength and scares his medium hands. He checks.

A king arrives - a credible scare card - and he checks. Best?

WhyThe king is the most believable card in the deck for your line - after three streets of aggression you'd hold one constantly - and this time it actually pairs you into top pair, top kicker. So there's no choice between value and bluff: the same bet does both, folding out worse queens while the hands that call are drawing thin.
What happensYou bet 4,000 and he folds a worse queen. The bet would have been a strong bluff on that card alone; pairing up just meant you'd have been happy to get called too.
You told a coherent three-street story, barreling cards that fit your range while picking up a flush draw, and the river king paired you so the final bet was value and bluff at once. Consistency, not raw aggression, is what got it through.

A triple-barrel gets through when the run-out tells one consistent story - keep firing cards that favor your range, and it works best when you carry equity to back the bluff.
