We must fold our once-strong overpair after the board runs out with two overcards and the opponent jams for full stacks.
On this Ten-high board, we have a massive range advantage. While we bet small, the solver actually prefers a much more polarized sizing to put maximum pressure on the BB's wide range.
Note: Sizing is too small; on this texture, we should use a larger size (pot or overbet) to maximize value and protection with our overpair.
When BB check-raises, we have a decision between calling and re-raising. Calling is standard to keep their bluffs in, though at this SPR, getting it in is never a mistake.
The Ace is a difficult card as it hits the BB's flatting range and check-raising range (AT, A8s, A3s). However, we must call the small probe to realize our equity.
Folding is the correct play. The board has run out poorly, and we now hold a weak third pair facing a massive overbet jam for our remaining stack. **Ranges:** The BB's line (check-raise flop, lead turn, jam river) is extremely polarized. While they can have missed spade draws, they have all the straights (QJ) and two pairs (T8, AT) that now beat us. **Board:** The King on the river is another overcard. We now lose to any Ace and any King, making our hand a very low-frequency bluff-catcher that doesn't block the primary value hands. **Math:** We need roughly 28% equity to call. Given the board texture and the way the action developed, it is unlikely the BB is bluffing at a high enough frequency to make this profitable. --- > **Takeaway:** When the board runs out with multiple overcards to your pocket pair and the opponent shows extreme aggression, be willing to let go of your 'big' preflop hand.
