Use aggressive check-raising on wet boards to isolate and deny equity, then commit on safe turns.
Flop Analysis
Checking is the standard start to our out-of-position strategy. After the small bet and call, our top pair is a prime candidate to check-raise for value and protection on this spade-heavy board.
**Ranges:** MP's small sizing often indicates a wide, merged range, while CO's call is capped but draw-heavy, containing many spade draws and weaker Tens.
**Sizing:** The raise to 17.5BB is significantly larger than traditional theory suggests. While it maximizes value from draws, it risks isolating us against only the very top of CO's range like 33 or AT.

> **Takeaway:** Check-raising top pair on wet boards protects our equity, but keep sizing moderate to keep worse Tx and draws in the pot.
Turn Analysis
With the SPR now below 1, we must follow through on our flop aggression. The 5h is a safe card that doesn't change the nuts significantly, and jamming is the most effective way to realize our equity.
**Math:** At 0.74 SPR, we are effectively committed. Jamming denies CO the chance to see a free river with their numerous flush draws like AsXs or QsJs.
**Board:** The board pairing the bottom card is generally good for the flop aggressor. It reduces the number of 5x combos CO can have, though 33 and A5s remain part of their sticky range.

> **Takeaway:** In low SPR situations, prioritize equity denial with strong made hands rather than playing a tricky checking game.
