100NL, WTF did he call with ?

villian is 16/13/3.1 with 26% steal and 54% fold to 3 bet over 1.4 k hands. My image was tight and clean( its really the first time i 3 bet him since i sat down). What else can i do to get better FE and exploit such an ass hole? a little over half psb cbet is my standard play on these flops these days. Should i just fold or flat call preflop against these obvious stealeres in a short-handed table? Should i cbet more, DB on the turn or bet something on the river in order for him to fold his shit?

1. you picked one of the worst hands to 3bet preflop
2. against a bad player type to 3bet against
3. and bluffed a calling station

3bet bluffing is the opposite of what you do when someone doesn't fold to 3bets.

wtf is going on here 26% is a low ats anyway
