Hero 3-bet JJ from UTG+1 against a UTG open, made a standard c-bet on a favorable flop, then correctly called off against UTG's check-raise all-in with an overpair. Solid line throughout.
Street-by-Street Analysis
Preflop (9/10)
JJ is a premium 3-bet against a UTG open. The $35 sizing (2.5x the pot faced) is standard and isolates well, building a heads-up pot in position.
Flop (8/10)
On T♦7♦5♥, Hero has an overpair — ahead of most of UTG's continuing range. The 0.7x pot c-bet is good. When UTG check-raises all-in for $245 into a ~$184 pot, Hero must call $190 more to win ~$434. UTG's line includes sets (TT, 77, 55), but also AT, overpairs like QQ/KK that flatted pre, and diamond draws like A♦K♦. Against top pair Hero is a ~76% favorite; against sets ~14%; against overcards with the nut flush draw ~48%. JJ is too strong to fold here at this stack depth — correct call.
Hindsight: UTG had T♣7♣ for flopped top two pair. Hero was behind but spiked a queen on the board to make a better two pair by the river, winning the pot.
