T7s freeplay hit flop w/ tree-of-a-kind

You can have PokerTracker 4 put the results in a "spoiler". (Go to settings in PT.) We don't want to know his hand as it may cloud the judgement.

Preflop: You'll get a million opinions. Checking and raising are both fine. I'd actually raise 2.5-3 bb to sweeten the pot.

Flop is fine.

Turn is fine too.

River: You'll get a million opinions. Some will be based on the theory that villain hates money. Others on the theory that he loves it. I'd fold myself.

Fixed

He has 9/0 stats 4 handed ?????
Looks like auto fold

Here we can follow the rule: Never play for stacks in limped pot without the nuts.
Fold and move on. There are a lot better hands.

If there was no flushes possible and turn didn´t bring straights I would consider calling. But as nitrol said, don´t play for stacks in limped pots :).
