K6s CO on 963r: Thin Value and River Sizing

Hero

Position
CO vs HJ
Pot
Single-Raised Pot
Flop
3♠ 6♥ 9♠

We successfully extracted value with second pair that improved to two pair, though our river sizing left money on the table.

Flop Analysis

Facing a small c-bet on this 9-high board, calling with second pair is mandatory. We have plenty of equity against their air and overcards.

Turn Analysis

When HJ checks the paired turn, we should lean toward checking back. Our hand has improved to two pair, but it's a marginal value hand that benefits from pot control. **Ranges:** HJ's check often contains overcards like AQ/AJ or medium pocket pairs (77-88) that are now in a tough spot. While we have equity, betting can isolate us against their 9x or better pocket pairs. **Board:** The board pairing the 9 is better for the preflop aggressor's range, as they hold more 9x combos. By checking, we realize our equity and keep their bluffs in for the river. --- > **Takeaway:** On paired boards where you hold a medium made hand, checking back preserves your range and prevents you from getting check-raised off your equity.

River Analysis

The King is a fantastic card for us, but our sizing is far too small. We should be looking to overbet here to maximize value against their bluff-catchers. **Sizing:** We used a 33% pot sizing, but solver prefers a 100% pot overbet. HJ's range is capped after checking twice, and they will often call a large bet with hands like TT-QQ or Ax that don't believe we have the King. **Ranges:** We now beat all their pocket pairs and one-pair hands like Ad9d. Since we have the nut advantage on this specific runout, we should use a polarized sizing to maximize the EV of our top range. --- > **Takeaway:** When the river improves you to a top-tier hand against a capped range, use large sizing or overbets to maximize value.

Note: Small sizing on the river misses significant value; an overbet is preferred to target Villain's capped bluff-catchers.
