T♥ 5♠ K♣

The line is good until the river, where jamming a mostly chopped nut straight into a capped range burns value by folding everything we beat and only getting called by hands that split or rarely beat us.

Flop Analysis

Flop Kc Th 5s heads up: our KhQh smashes this—top pair with great kicker plus a gutshot to Broadway and some backdoor potential. Into 9BB, betting 2.8BB (about 1/3 pot) is a solid, low‑variance value bet versus a limp–call range full of Tx, 5x, pocket pairs, and random suited broadways. Small sizing lets worse Kx, Tx, JJ–66, and straight draws continue comfortably, which is exactly what we want, while not overinflating the pot with a hand that can still be behind some slowplayed strong Kx or sets. Checking sometimes would be defensible for pot control and range protection, but this small stab is very standard.

Turn Analysis

Turn Jd makes the board Kc Th 5s Jd, bringing in Q9 for a straight and adding more connectivity to villain’s limp–call region (Q9, 98, extra gutters). Our KhQh now has Broadway, the top possible straight. Pot is ~14.7BB and we go 9.1BB (~60%); sizing up is reasonable because our hand is at the top of our range and villain can still have plenty of strong but second‑best holdings: KJ, KQ, KT, sets, two pair, and various pair+draw combos. The key here is to choose a size that continues to get called by those worse value hands and draws—this size still comfortably does that versus a limp‑call range that tends to be underdefended versus aggression, so betting is clearly preferred to checking.

River Analysis

River Ah makes the final board Th 5s Kc Jd Ah and keeps our KhQh at Broadway, but crucially, any Qx that plays for a straight also has the same hand—this is a heavily chopped nut region. Pot is ~32.7BB and SPR is ~2.5, yet we choose an 84.3BB jam, ~2.6x pot. That shove massively polarizes us in a spot where value mostly wants to get called by one‑pair/two‑pair/sets that are now very uncomfortable; a limp–call range will overfold those to a huge overbet. In practice, that sizing mainly gets action from hands that share Broadway with us and, on the margin, the very few combos that might beat us, while forcing almost all dominated value to fold.

Note: The 2.5x pot river shove with a mostly chopped nut straight is too big: we fold out the worse hands we’re targeting, get called mainly by hands that split (or rarely beat us), and leave a lot of EV on the table compared to checking or using a normal 40–70% pot value bet.
