5/10NL Big turn c/r semibluff

[Hiltonian]

Hand is against someone named AustinJill. Don't know if anyone has played with him, but from what I saw he has a somewhat odd style, and we had been tangling a lot. Pf he seems to play more tagish but I noticed he was VERY often floating my continuation bets in position and then waiting until the river to bet ~2/3 the pot often on a complete bluff. There was also one other big reraised hand I played with him earlier where I threebet in position pf, he called, and then bet almost full pot into me oop. I raised him allin and he quickly folded.
