Flopped trips line check 200$ 6max

[gsdavid]

Preflop
Villian has 142$ and I have him covered. He is running at 43/20/1.8 after 30 hands. He raises to 8$ in MP i decide just to call with in SB since I want bit better read on player before i reraise him OOP.

Flop
Pot: 18$
I check he bets 12$ and I decide just to call. Am i better off raising him here or should i let him possibly continue bluffing?

Turn
Pot: 42$
This was probably the worst turn card for me so i decide to check. An then...villian for some reasons minbets...Now I have no reads what so ever what this means so i decide to CR to 24$ just to see how he reacts and protect from additional draws.

River
Pot: 90$
I decide to VB to 42$ to get a possible call from AK or some Tx hand. Suddenly he insta miniraises. Hero? It this a ok line? Since this is not a regular, i do not need to mix up my lines so I ask what is the best EV line to take? tnx
tnx
