Flatting KQs pre is standard; calling flop and folding turn versus the second barrel is reasonable, but solver prefers a mix of call and semi-bluff raise on the turn.
Flop Qh 9d Ts is very favorable for us—top pair with a gutshot on a board that connects well with SB’s limp range. Facing a small c-bet, we’re getting about 2.6:1 and need ~28% equity; with top pair plus a strong draw, calling is the natural choice. Solver also mixes in some raises, but calling is the main line.
Turn Ad is a big card that improves SB’s range: they can now have Ax, sets, and strong draws. We still have top pair with a gutshot and are getting about 3:1, needing only ~25% equity. Solver prefers a mix of call and semi-bluff raise here; folding is defensible but slightly too tight given the price and our equity.
Note: Folded turn versus the second barrel; solver prefers a mix of call and semi-bluff raise here, so folding is slightly too tight given the price and our equity.
