Preflop
Villain has 120$ in this hand and I have him covered. He is running at 42/20/3.8 after 120 hands and seems a bit spewy. He has a mediocre concept of how to play but he fails to control his lagtard side. Its 5 handed, folded to him on OTB and he raises to 8$. I decide just to call since I'm not sure that he would fold to my OOP raise and might float me/make a move on me on a A high flop. I'm in SB with

Flop
Pot: 18$
I check to induce a CB, he makes a donkbet of 8$ and i decide to CR to 24$. Unfortunately he insta pushes. At this point he can have almost any 2 hands that he thinks are worthwhile playing. I doubt that he would be doing this with air. Easy fold? How's the line prior to CR? should I CR to at least 30?

Leading or check raising the flop are OK.

Calling this all in is not unless youve seen him do this before with just overcards (and no flush draw).
