On the river with your check on the turn you represent exactly what you have in the eyes of the villain, a medium strenght hand. Dont think he has a busted draw, what sense would it make a very good player call OP with a strong draw (flush draws with an over ) and then shove almost 2x pot on river. There s few combos of J9 and KJ that he could have, think that on the river the only thing you can beat is a hand like 7s6s and some Tx hands that turned to a bluff, which i think its unlikely :S . Hands for value : Any Qx that he defends the BB (the way you played the hand i think that he would feel good with about any Q), some 4x( with a backdoor flush draw) . Bluffs : (suited spades middle connectors) and pairs turned to a bluff. 

Now think with me, your check on the turn is either to pot controlling to call a decent size river bet or is to give up on the pot. Thats what is in his mind. So now he thinks : What s the best size i should now make since he is probably bluff catching me. Hmm what about it all ? Its the bubble he will think that im just messing with him and this is the only way i can win the pot, and my range is super polarized, how can he put me in 4x hand? Some pros mind are tricky to enter, but look with a deep thought in things, and then think why they did that. 

Interesting hand. Gl on the tables.

I think the river is close you have a good  bluff catcher and I am not sure that he rips the flop with his bad FDs (67s etc). I agree it's unlikely he has a set (preflop/combos) or QT (flop) or a good queen (flop/river overbet)  so think his value range is pretty narrow especially since he probably folds some 4x on the flop. 

Isn't his bluffing range more important than his value range here? I mean, he can't rep much, but if he's never bluffing, we can't call even if he reps 2 combos. Actually, vilain can probably value bet KQ and AQ, so that's quite a number of combos ; don't know if he would be willing to shove though.

Would have been better not to see the results on the hand IMO. Overall, having seen the vids from James Obst (vilain), I wouldn't think he bluffs a lot when he can't rep much. His agression is very much in control.

Now let's look at other factors: vilain covers you by a large amount, he has room to pressure you, especially because it's the bubble. Still, you say you lost a big pot just before : IMO it makes it way less likely vilain will try a big bluff over you, it's just bad timing, especially since you're probably not opening very wide just after you lost a pot => most players would cling to their chips and not spew when everyone might think they're tilted => your preflop range (UTG) is not wide to begin with, so he's less likely to try and bluff a strong range.

Last point: your postflop range is mostly hands that can't beat Qx, vilain probably has a profitable bluff by betting small ; so when he overbets shove, I'd say it's more likely he's trying to make you hero call than hero fold.

Still, I think overbetting all his range (monster, thin value and bluffs) on this range would be pretty good. IMO it's a good spot to bluff in a vacuum, but it's also pretty easy for him to value town you with Qx (and better obv) + conditions are not great for a bluff (you might be tilted, etc). So I'd fold the river keeping 20bb and a chance to survive the bubble.

Think when you take this line. Your hand is pretty face-up. Would have been sexy to see McLeod do this with just a Queen
