We flopped trips and turned a full house; while betting is fine, checking the turn often traps more bluffs on this board.
We have the effective nuts here. While we should bet for value, a larger sizing (50-75% pot) is preferred over the small 33% stab to build the pot and charge Villain's pocket pairs.
Note: Sizing is too small; on paired boards where we have a massive nut advantage, we should use larger sizes to maximize value from Villain's calling range (88-JJ).
Our hand has improved to a full house, but the board is now extremely locked down. Checking is the preferred strategy to allow Villain to catch up or bluff with their air.
Note: Betting here is slightly thin; checking back traps more effectively since we block the most likely calling hands (Ax) and Villain has very few ways to continue.
