Flop Analysis
Checking range from out of position after calling the 3-bet is mandatory here; BTN is the preflop aggressor, has the initiative, and this paired, low board is easy to defend by check-calling or check-raising portions of our range.
Preflop is fine and the flop check is good, but the flop check-raise with JJ and the ultra-tight fold facing a tiny turn bet burn a lot of EV.
Checking range from out of position after calling the 3-bet is mandatory here; BTN is the preflop aggressor, has the initiative, and this paired, low board is easy to defend by check-calling or check-raising portions of our range.
With an overpair and medium SPR, calling the small c-bet is much better than check-raising small; the raise mainly folds out worse hands and keeps in stronger ones. **Ranges:** After we flat pre, our range is pairs like 99–QQ, some Ax suited, and a few suited connectors; BTN’s 3-bet range still contains overpairs, some 9x, and bluffs. JJ is near the top of our medium-strength holdings and functions very well as a bluff-catcher rather than as a raise-for-“protection” hand. **Board:** The paired, low board is excellent for our underpairs and overpairs to 9, but BTN retains high-card advantage and all the strongest boats; raising here polarizes us in a spot where our actual hand is more in the middle of our range. **Sizing:** The raise from 14.2 to 30.4bb is too small to credibly polarize or commit; it doesn’t fold out many better hands, and it shrinks SPR further while denying BTN the chance to continue bluffing. --- > **Takeaway:** On paired boards at low SPR, let JJ earn by calling small c-bets rather than using thin, small check-raises that isolate you against stronger hands.
Note: The flop check-raise with JJ at this SPR is a clear deviation from best play; calling the small bet keeps BTN’s bluffs and weaker hands in and avoids bloating the pot versus a stronger, more nutted range.
After we check-raise flop and get called, checking the turn on this high, diamond card is correct; our hand has clearly shifted down to more of a bluff-catcher and we should not donk or overplay it at this low SPR.
Folding to the tiny turn stab is a serious over-fold; with second pair, very strong pot odds, and a short SPR, we should call and see a river. **Ranges:** Once BTN calls our flop raise, they have strong 9x, overpairs, and some slowplayed monsters, but also some floats with overcards or diamond draws; second pair is still ahead of all missed overcards and some bluffs, especially facing a tiny sizing. **Math:** We are getting about 6.3:1, needing only ~13.6% equity to continue; second pair with outs to improve to a full house or quads almost always meets that threshold even if BTN is underbluffing somewhat. **Plan:** Given the remaining stack is small relative to the pot, the most sensible strategy is to call and then re-evaluate river versus sizing, rather than folding and surrendering our equity in such a big pot. --- > **Takeaway:** At NL200, don’t let scary cards plus a small bet talk us into folding strong bluff-catchers when the pot odds are this good.
Note: Folding second pair to a tiny turn bet with huge pot odds gives up far too much equity; this should be a clear call.
