Let me add that MP2 had about a 200BB stack. Also, no good reads on him as I had just sat down at the table. My fold was partially read-based, as his turn minraise was almost immediate. Dunno, I felt like this was insufferably nitty, but at the same time, didn't see a great alternative.

NF.

Some people just minraise to arouse suspicion, especially if they just sat down. Doubtful he had the other 7. Not sure I would have folded. What's wrong with re-raising on the turn?

I'm not sure how many people minraise the turn in a multiway pot just to arouse suspicion. Also if I 3bet any significant amount, say $45-50, am I not getting close to pot-commitment?

Call the min raise, block bet the river? He could also be trying to get check/check on the river or just "seeing where he's at" with a ten/overpair.

Also, I thought immediate min-raises tend to come from weaker hands, but either way it prob isn't too reliable of info.
