With top pair and a strong price on the river, folding to the shove is too tight—this combo should continue versus a polarized range.
Flop comes Q27hh, giving us top pair with a decent kicker. BB has a small range advantage here, but we’re in position and the pot is already sizable. Facing a small 5bb c-bet into 16.5bb, calling is the main line—raising mostly isolates us against stronger queens and overpairs, while folding gives up too much equity.
Turn 8c is a big card for BB’s range and adds a club draw, so their second barrel is weighted toward value and strong draws. We’re getting about 3:1 and still have top pair with reasonable equity, so calling is standard. Solver prefers calling almost always here, with only a small mix of raises.
River 9s completes the 9-high straight and BB jams 19.5 into 61, giving us ~3:1 and needing ~24% equity. Solver treats this as a mandatory call with top pair; folding gives up too much equity versus a range that still contains bluffs and worse queens.
Note: Folding top pair to the river shove is too tight; we’re getting a strong price and should continue versus a polarized range that still contains bluffs and worse queens.
