Hero Opens QJhh to 7. 
Gets Called in 4 spots.

Flop: (38 pot)
Th9h6.

Cbet of 20. V1 and V2 call.

Hero-> Looks like Internet Kid
V1 -> Internet Kid clearly.
V2 -> Thinking late 20s probably does not play on internet but clearly not terribad.

Turn: 7h. (98 pot)

Here is where it gets interesting.
I take what is probably a nonstandard line -> Hero Checks, V1 checks, V2 barrels 35. Hero Flats. V1 raises to 125. V2 Folds. Hero Calls.

River: Jx (383 pot)

Hero checks. V1 jams 215.

Hero: ??

Thanks for your feedback in advance guys 

Aside from just what your river decision would be, it would be great to get your opinions on the following:

1) Opinion on checking turn. I imagine that responses are going to be weighted towards always barrel (bad not to 2 barrel as you lose value from sets/straights/AhX)

2) Villain's range when he check/squeezes.

Thanks!!
