A5o BB on K64r: Capitalize on Capped Ranges

Flop Analysis

After SB checks, we should frequently stab. While we only have Ace-high, the board is dry and SB's check suggests they missed, allowing us to take the pot down immediately. **Ranges:** SB should be c-betting most of their Kx and strong draws. By checking, their range becomes capped at marginal pairs (6x, 4x, 77-TT) or total air, which we can pressure. **Sizing:** A larger sizing (60-70% pot) is preferred to maximize fold equity against their high-card hands and small pairs that are indifferent to calling. --- > **Takeaway:** When the preflop raiser checks a dry, high-card board, use a larger sizing to punish their capped range.

Note: Sizing is a bit small; a larger bet (approx 4.3BB) generates more folds from SB's air and marginal hands on this dry texture.

Turn Analysis

Checking back is the correct play. We improved to top pair, but SB's range still contains many Ax combos that checked the flop, and we don't need to turn our hand into a bluff or thin value bet yet. **Ranges:** The Ace is a better card for SB's range than ours, as they open all Ax preflop. By checking, we keep their bluffs in and control the size of the pot with a hand that has high showdown value but mediocre kickers. **Plan:** We are in a great position to bluff-catch most rivers or go for value if SB checks again. Checking back protects our range and ensures we realize our equity. --- > **Takeaway:** With top pair and a weak kicker in position, checking back the turn often maximizes EV by keeping the opponent's bluffs in.

River Analysis

Once SB checks a third time, we have a clear value bet with trips. SB is extremely unlikely to have an Ace or better after checking three streets, so we are targeting Kx and mid-pairs. **Ranges:** SB's range is heavily condensed into marginal made hands like Kx, 88, or 77. They would almost certainly bet an Ace or a full house themselves to get value from our Kx. **Sizing:** A medium sizing (60-75% pot) is ideal. It's large enough to get paid by a stubborn King but not so large that we polarize ourselves and force folds from the hands we want calls from. --- > **Takeaway:** When an opponent checks three times on a board where you hold trips, go for a clear value bet against their capped bluff-catchers.
