Semi-bluff raising the flop with the nut flush draw is standard at this depth, but use smaller sizing before calling off the shove.
Flop Analysis
Raising with the nut flush draw is an excellent semi-bluff that pressures UTG+1's c-betting air, but our raise sizing should be closer to 3.6BB.
Note: Raise sizing to 6.5BB is unnecessarily large at 16BB effective; a min-plus raise to around 3.6BB achieves the same fold equity.
Flop Analysis
Calling off the rest of our stack is mandatory after putting in the raise with such massive draw equity.
**Math:** Getting 2.6:1 pot odds, we need just 27.7% equity to break even. Against UTG+1's shoving range, our nut flush draw and overcard give us roughly 50% equity, making this an easy call.
**Ranges:** Even when UTG+1 shows up with overpairs like JJ or QQ, our nut flush draw provides plenty of outs to comfortably realize our share of the pot.

> **Takeaway:** Once you raise a premium draw at a shallow SPR, you are priced into calling off any subsequent shove.
