2♦ 6♥ 8♠

We correctly checked back a dry flop to protect our range and then capitalized on a river King to stack Villain's bluff-catchers.

Flop Analysis

While betting small is the preferred frequency to leverage our range advantage, checking back is a high-EV alternative that protects our checking range. **Ranges:** We have a massive advantage with overpairs (JJ-AA) that SB lacks after just calling the 4-bet. SB's range is condensed toward hands like TT-99, AQs, and some AJs. **Board:** This is a very dry, low texture. Since SB is unlikely to have many 8x or 6x combos in a 4-bet pot, our AK high still holds significant equity and can comfortably take a free card. --- > **Takeaway:** On very dry boards in 4-bet pots, checking back high-equity overcards is a viable way to balance your range and induce bluffs.

Turn Analysis

Facing a small probe bet on the turn, we have an easy call with our overcards and the board-pair of eights. **Math:** We are getting over 5:1 on a call, requiring only ~16% equity. With two overcards and the current pair of eights, we are well above this threshold against SB's stabbing range. **Plan:** By calling, we keep SB's bluffs in (like QJs or A5s) while maintaining a manageable pot size. If we improve on the river, we are in a perfect position to value bet or raise. --- > **Takeaway:** When offered excellent pot odds with high-card strength on a paired board, calling is superior to raising as it keeps the opponent's bluffs wide.

River Analysis

The King is the perfect card. SB's lead for nearly 75% pot looks like a polarized attempt to fold out our remaining Ace-highs, making our top pair an easy shove for value. **Ranges:** SB's range is heavily weighted toward pocket pairs (99-QQ) that are now bluff-catching. Our range contains all the AK and KK combos that SB cannot easily represent after the turn lead. **Sizing:** Since the effective stack is less than the pot (SPR < 1), any raise is effectively an all-in. We are targeting SB's middle pairs that feel priced in to call. --- > **Takeaway:** When the river completes your top pair in a low SPR pot, prioritize getting the rest of the money in against a range that is likely to feel 'committed'.
