While we made a straight on the river, the heart flush also completed, making our raise-call extremely thin against a polarized range.

Flop Analysis

Checking back middle pair is the most robust strategy here. We have decent equity but aren't strong enough to value bet three streets, and checking protects our range.

Turn Analysis

Checking is preferred, but betting small is a viable mix. We have middle pair and a gutshot, but the board is getting wetter, making pot control attractive.

Turn Analysis

We have a mandatory call after being check-raised. We have middle pair, a gutshot, and the price is too good to fold given our equity against bluffs and draws. **Math:** We need roughly 24% equity to call the raise. With a pair and a gutshot, we have roughly 48% equity against the BB's range, making this a clear continue. **Ranges:** BB's check-raise range includes strong value like sets (88, 55, 22) and two pairs (85s), but also many semi-bluffs like flush draws and open-enders (76s). --- > **Takeaway:** Don't fold pairs with additional draw equity when getting great pot odds in position.

River Analysis

The river 3h is a double-edged sword; it completes our straight but also brings a heart flush. Raising is a high-variance play that risks running into the top of BB's range. **Board:** The 3h is highly connected. It completes the 6-high straight for us, but any two hearts in BB's range (like AhXh or 7h6h) just made a flush. **Sizing:** If we do raise, we should lean toward a call or a jam. The small raise to 13.5BB is awkward as it doesn't maximize value from worse and gets punished by the nuts. **Blockers:** We hold the 6c, which is a key card for straights, but we don't block any hearts, making it more likely BB has the flush they are representing. --- > **Takeaway:** When a straight completes alongside a flush, be cautious about raising for value, as you often isolate yourself against the better hand.

Note: Raising the river is overly ambitious; the 3h completes flushes, turning our straight into a bluff-catcher against a polarized lead.

River Analysis

Once we are 3-bet shoved on, we are in a miserable spot. We need 23% equity, but BB's line is extremely polarized toward flushes and very few bluffs.
