Floated flop, turned set, facing C/R from TAGG 50NL

Villain is 15/14/3.5 over 120 hands, 41 steal %, and 100% cbet flop. Have no history with him. My plan was to float flop and try to take away with a turn bet, but now I turned a set and confused about his C/R

raise flop is better than float here imo

as played just shipit. We have the only nut hand in our range.

standard shove, don't get fancy or scared

he probably turned a combo draw
