3bet bluff shove 200nl

this guy is a donk. he runs 50/32/1.5 with a 3bet% of 26. ive just been hammering on him IP and i guess he decided to adjust by 3betting me aloooooot. He started doing this recently so there's been two 3bet flops seen, each of us winning one small one. MY question is, is this fine vs. a slighltly tilting fish?

obviously im repping a strong draw but idk what level he's on other than its probly the basement floor. and fwiw he took about 2-3 secs before min raising.

From a bad player the c/minraise is probably gonna be some sort of made hand and never a bluff (and i doubt it's really a bluff from any player), and i doubt you can fold a made hand off a tilting player on this board.

yeah no

this seems really bad to me, specially against a bad tilting player who i doubt is folding much at all here, if your convinced hes fos just float him and see what he does on the turn, i wouldnt be surprised if he called your all in with ak/aq looking at his tendencies.
