The thing is that nervousness =/= bluff.
Nervousness usually just means that this hand means a lot to villain. This could be because he's a short-stacking nit who's not used to playing pots this big. It could be because he has a monster, and "I swear to fucking god if I blow it with the nuts again, I'm gonna go straight home and beat my wife." It could be that he's been thinking the whole hand that he has some massive soul read bluff and now that he's acting on it he's like, "oh shit, is he already committed? I thought I had more chips? Oh shit, I guess he COULD have had KJ, and now the flush doesn't scare him anymore! OH SHIT CAN HE TELL I"M NERVOUS!!!!" Etc.
I think the best time that nervousness is a tell is 1) When the pot is small. The only reason someone's nervous in a small pot is because the hand means a lot to them already, which of course usually means they have a monster (it can logically also mean that they plan on running a huge bluff already, but lol at these type of players charting out big bluffs several streets in advance) or 2) it's clearly a hollywood.
Obviously the pot's already big, and though the blinking is very easy to hollywood, blurting stuff out and saying stuff in a nervous voice that's believable would take mad skillz.
This doesn't mean that your tell doesn't mean something, it's just that it's gonna take some analytical thinking (what hands would he be nervous about, and which would he not think much about) moreso than just "lol him being nervous always means _______ here."
I know I didn't answer your question, but if I'm not mistaken this thread is kind of a place to discuss what this sort of tell can mean.
In the hand itself, I'm much more concerned about the call turn for 110 and fold river to 190 line. Though we have different outs against different hands, we more or less have 3 outs to scoop and 3 more outs to chop. That's a 7% chance of winning the pot outright, and there isn't much money left, so if we think we're beat on the turn than we should just fold on the turn.
I don't think his river shove strengthens his range so much that we're like "well, hell, we were ahead on the turn but now he's shoving his last bit of stack!" I mean, there isn't a ton of money left, and he could just be shoving because he has a hand with strong absolute strength without really knowing if better's folding or worse is calling because he doesn't feel like c/f'ing his strong hand. Likewise, he could be just as likely to check the nuts.
So I think call turn/fold river's bad. OTT I'd either shove, call twice or just fold.
