Flop
2♥ 5♠ 9♠

We successfully extracted value by checking the turn to trap with top set, though we must be careful on flush-completing rivers.

Flop Analysis

A small c-bet is ideal on this semi-wet board to keep SB's range wide while extracting value from pocket pairs and spade draws.

Turn Analysis

Checking back top set is a high-frequency trap. We block the hands SB would call a bet with (Kx), so checking lets them bluff or catch up with a second-best hand. **Ranges:** We hold the effective nuts, blocking SB's top pair combos like AK/KQ. By checking, we allow SB's middle pairs (TT-QQ) and spade draws to continue to the river. **Blockers:** Holding the K♠ is significant as it blocks the second-nut flush draw, making it less likely SB is drawing to a hand that will fold to a turn bet. --- > **Takeaway:** When you crush the board and block the calling range, checking back can be the best way to maximize total pot value.

River Analysis

Shoving is a viable value line, though checking back is often preferred to protect our checking range when the flush completes. **Board:** The 8s is a difficult card as it completes the spade flush and the 67 straight. While we have trips, we now lose to any two spades in SB's range. **Sizing:** Going all-in for roughly pot-size targets SB's remaining sets (99, 55) and stubborn overpairs that don't believe the flush. However, against a disciplined opponent, this sizing might only get called by hands that beat us. --- > **Takeaway:** On river cards that complete multiple draws, consider checking back strong non-nutted hands to avoid value-cutting yourself against a polarized range.
