2♥ 4♠ K♠

We should call the river with our two pair; folding here over-folds to a polarized range on a board where many draws missed.

Flop Analysis

Checking is the preferred play with second pair. We have decent equity but don't want to build a massive pot against a range that contains many Kings.

Turn Analysis

Checking is mandatory on this turn. The Jack is a better card for the caller's range, and we now have a flush draw to go with our pair, making this a perfect check-call candidate.

Turn Analysis

We have a clear call facing the half-pot bet. We have middle pair and a nut flush draw, giving us massive equity and the ability to realize it cheaply.

River Analysis

Checking the river is correct. Our hand has improved to two pair, but it functions best as a check-call to let the BTN bluff their missed spade draws.

River Analysis

Folding is a significant mistake. Our two pair is near the top of our bluff-catching range, and the BTN has many missed spade draws (QsTs, Ts9s) that must bluff this runout. **Ranges:** BTN's range is polarized between trips (Jx) or better and total air. Since we checked twice, BTN will frequently attack this pot with missed draws that cannot win at showdown. **Math:** We are getting 2:1 on a call, meaning we only need to be right 33% of the time. Given the number of missed spade draws and low-equity floats BTN can have, our hand wins significantly more often than that. **Blockers:** We do not block the missed spade draws, which is actually good for calling. We want Villain to have those specific air combos in their range when they bet. --- > **Takeaway:** When the board pairs and draws miss, don't fold the top of your bluff-catching range to a single pot-sized bet.

Note: Folding two pair here is too tight; we need to call to prevent Villain from profitably bluffing all their missed draws.
