Trashcona ??

I think i shove here. Tough spot though, the pot is just so huge and it seems like theres a good chance you have the best of it.

First off, i would fold this trash preflop. For the flop i think you played it fine. This is a heavy heavy draw flop though, maybe raise a little more.

No heart came off on the turn and nothing to help complete the straight. I think the majority of the draws you see here are going to be two hearts and maybe someone with a 10 or a pair and a 10 etc. Doesn't seem like anyone has a made hand at this point, as they would raise the flop. (I guess depending on how passive they are) When you say freccia has been acting nitty, how nitty? do you have pt/hud? if so what does he run at? This would help a lottttt.

Imo, anyone who is decent with a set, two pair, or even probably a flopped 910 would raise that flop. I can't see a hand that now has us beat that wouldn't raise the flop. Also, if he had a boat, wouldn't he wait for you to raise, then reraise? or wait to the river when someone hits their flush/str8 and extract more value? Maybe he is on a poorly played 910?
It seems like he either has 9/10, a 7, or some other poorly played hand.

It seems like the two unknowns are just bad stations chasing some sort of draw. So i shove, but i guess it depends on how "nitty" freccia is and your reads on the other players in the time they have been there. If freccia runs like 12/5/.8, i fold here etc.

Ideally everyone is on draws and feccia hit three 7's and thinks its good. But as i said, i probably shove here, tough spot though not too sure if this is +ev but the pot is just huge. Also, this hand is almost entirely based on your reads/hud imo, especially regarding feccia.

Sorry, freccia has been nitty post flop only. He's been seeing lots of flops and is very passive preflop, but I've only seen him show down good(not necassarily the nuts) hands.
