55 BU on 922pr: Full House, Bad River

Flop Analysis

Stabbing is fine in theory, but the sizing is far too big; with second pair on a dry paired board we should either check or use a small range bet, not a near-pot overbet multiway. **Ranges:** CO has all the strong overpairs, 9x and better boats, while our flatting range is wider and more capped; second pair is a medium‑strength hand that prefers pot control or low‑stress small bets. **Sizing:** Solver wants us mostly checking this exact hand, and when betting, using ~⅓ pot — a big bet bloats the pot with a marginal hand and forces worse hands (like random overcards) to fold while isolating us versus 9x and better. --- > **Takeaway:** With medium‑strength hands on dry paired boards, favor checks or small stabs, not big bets that build pots against stronger ranges.

Note: Betting almost pot instead of checking or using a small ~⅓‑pot stab with second pair on a dry paired board overplays our hand and polarizes us unnecessarily.

Flop Analysis

Once CO check‑raises, calling is mandatory — second pair with our price comfortably clears the equity threshold against a polarized range of trips/overpairs and bluffs.

Turn Analysis

Facing the turn bet after we boat up, we should usually raise for value and to deny equity; just calling leaves too much money on the table given SPR and how many worse hands can pay. **Ranges:** CO’s check‑raise flop then bet turn range is value‑heavy (9x, overpairs, 2x, some spade draws), and our 5s full crushes everything except higher full houses and quads — we’re near the top of our range. **SPR:** With an SPR a bit over 2 and ~100BB effective behind, raising now lets us cleanly stack CO’s overpairs, 9x and random 2x, instead of risking awkward rivers where action can die or scare cards (like spades) appear. **Plan:** Raising to something like ~3× (to ~48–52BB) sets up a natural river shove; calling keeps the pot small and relies on villain continuing to barrel thin, which we can’t assume. --- > **Takeaway:** When you improve to a strong full house in a low‑SPR pot versus a value‑heavy range, prioritize raising the turn to lock in value rather than slow‑playing.

Note: Calling instead of raising turn with 5s full in a low‑SPR pot under‑realizes value versus CO’s overpairs/9x/2x that will often pay off a raise.

River Analysis

River facing a big bet, our 5s full is actually the bottom of our full‑house region and should mostly fold — the price is fair, but CO’s polarized range is too value‑heavy here. **Ranges:** After check‑raising flop and barreling turn, then bombing river, CO strongly represents 9x full, 8x full, higher pocket‑pair full houses and quads, with far fewer natural bluff combos; our hand loses to all higher boats. **Math:** We’re getting ~2:1 and need ~33.7% equity, but this combo’s EV as a call is negative in the sim — we need CO to bluff a lot, and most players drastically under‑bluff this line, making folding even better than theory. --- > **Takeaway:** Versus big polarized river bets after strength has been shown on earlier streets, be willing to fold your weakest full houses when they lose to most of villain’s value.

Note: Calling the large river bet with the lowest full house overestimates villain’s bluffing frequency in a spot where their range is heavily skewed to stronger full houses and quads.
