We navigated a wet board with an open-ended draw, called a turn raise with great odds, and trapped the river for a maximum payout once we hit the nuts.
Checking is the preferred play here. As the caller, we lack the range advantage on this broadway-heavy board, and our open-ended straight draw functions best as a check-call to realize equity.
Note: Leading into the preflop raiser (donk betting) on this texture is generally inefficient; checking allows us to see how Villain reacts and protects our range.
After our flop lead was called, we should lean toward checking. Our hand has significant equity but betting 75% pot into a neutral range advantage is overly aggressive with just high card.
Note: Sizing up to 8.4BB is too polar; a check or a small 33% pot bet better balances our range while keeping us from getting blown off our equity.
Facing the min-raise, we must continue. While the solver prefers a jam to maximize fold equity against their bluffs, calling is acceptable given our excellent pot odds.
The Ace is the perfect card, giving us the nut straight. Checking is the pure GTO play here to allow Villain to fire their remaining bluffs or value-bet worse hands.
An easy all-in. We have the effective nuts and Villain has committed themselves with a near pot-sized bet.
