I think we can bet the turn for value.

I assume villian isnt strong c/r this board because I see it a lot c/r a paired board and then giving up when called.

As played I dont think we can value bet the river 1 oesd he might play aggressiv on the flop got a bigger pair then our 7 other then that we vbet against j7 and 27-67 and some pocket which he propalby will not call. So I like a cb better.

many peps check raise bluff on paired boards when he checks the turn with the Ace i don't expect this to hit the villain as most raise pre with an ace so i would bet turn for value and if raised i would fold (if he double check raises i expect the 8 alot of the time)

if called on turn i would check river as the ten is not great for us some straights got there 6,9 : 9,J : as well as hitting some showdown value with hands like 9,T : T,J premium overs hands like K,T : QT that villain did not 3bet etc so i would check the River

(warning: i'm just a fish in the sea)

I think I would shove on the flop after that reraise. Imo a 8 would never reraise on this rainbow flop, and therefore the only hand I can see beating you is K7. You get a lot of calls with other 7x's that your hand beats. 

As played I would bet both turn and river, like 150-ish turn and a bit under half the pot river. I hope to get a call from other 7x. 

Yep. I’m new here and I don’t speak English very well. Also, I’m a HU beginner (MTT player) but I give you my thoughts: I’d do the same cbet/call OTF. OTT, I’d check even if I think we are often ahead: K7 (8 combos) beats us and I guess he’d have bet A7 OTT and 3bet 99+ pre. OTR, you split with all 7x (except 87, A7, T7) , I think I’d often check and sometimes bet for thin value something like 80 or 100 if I think villain is able to call with 33-66 (but I think most of the times villain will fold). If villain has already c/r us with a straight river or c/r bluff, I’d check 100% time (I think our hand isn’t strong enough to be a good bluff catcher).

Well played, sir. I like your line.
