JJ is a premier bluff-catcher on this runout, but facing a pot-sized bet requires a disciplined approach against a range that contains several straights.

Flop Analysis

We have a clear call with our overpair. SB's range is polarized, and we are way ahead of their bluffs while trailing only the very top of their value range. **Ranges:** SB's 3-bet range includes AA-TT and AK/AQ. On this T-high board, we beat all their air and lose to AA, KK, QQ, and TT. **Math:** We are getting 3:1 on a call, requiring roughly 25% equity. Our overpair has significantly more than that against a standard 3-betting continuation range. **Sizing:** SB's half-pot sizing is standard on dry textures to extract value from Tx and protect against overcards. --- > **Takeaway:** In 3-bet pots, overpairs on low boards are mandatory continues but rarely want to raise and bloat the pot against the top of the opponent's range.

Turn Analysis

Checking back is the highest EV play. We protect our checking range and avoid over-committing against the few straights that just completed. **Board:** The 2h is mostly a brick, though it does complete a specific straight (45s) and introduces a flush draw. **Plan:** By checking, we keep the pot manageable and allow SB to continue bluffing on the river with their missed broadway hands or heart draws. --- > **Takeaway:** When the preflop aggressor checks a safe turn, checking back with marginal value hands protects your range and controls the pot.

River Analysis

This is a very close decision against a pot-sized lead. While SB can have straights, our hand is a prime candidate to call down given the missed draws. **Ranges:** SB's line (Bet-Check-Pot) is highly polarized. They likely hold either a monster (TT, 89s, 45s) or a total bluff like missed hearts (AhKh, AhQh). **Blockers:** Not holding a heart is actually a benefit here; it leaves all of SB's missed heart draws available in their range to use as bluffs. **Math:** Facing a pot-sized bet, we need 33% equity to break even. While the solver leans toward folding at a high frequency, calling remains a viable mixed strategy with positive EV. --- > **Takeaway:** On brick rivers where draws miss, overpairs without relevant blockers are the primary candidates for calling down polarized bets.
