Open AKs, mostly 4-bet vs BB’s 3-bet, and once we flop top pair, lean on checking turn and river rather than building a huge pot.
Flop Kd9c2s, we have top pair top kicker on a dry board; facing a small donk, solver prefers calling with this combo, but a large raise is acceptable as a mix. Raising here is fine, but it’s not the default line—calling keeps the pot smaller and avoids overplaying our hand on a board that favors BB’s 3-bet range.
Turn 7h, SPR ≈0.5; with top pair and no draw, checking back is reasonable and avoids getting check-raised off our equity. Solver is close between betting and checking, but checking is a solid, low-variance option.
River 4c, BB shoves 49bb into 143.5bb; we’re getting about 2.9:1 and need ~25.5% equity. Solver is split between call and fold, but given the pot odds and our hand’s strength, calling is reasonable. We’re not folding top pair here.
