That guy probably had a raise first of 100% from any position on that ft, so when he reps so narrow going for 3 streets and big on the river ,  makes nsb blockers a good candidate to call him down.

Having a Q with no heart in your hand here makes for a deece spot to hero if the guy is a total banana. If he's in line I think we need to find a fold here. 

The hand is cool to think about because it's somehow spectacular. Yet, there are potential key elements that we won't have, such as: sizing tells, timing tells, and strategic implications. We also don't have reads on ranges that players might have (for instance, some players will not value bet thin often enough with, say, A9. or they would take a different line). Maybe the chip leader is expected to get out of line more often than not.

We don't know NeverScaredB's plan for this FT, either. He might have found strategically interesting to make a big hero call (if it works, I can see many advantages: becoming chip leader first + the thin call gives you a great momentum, a fearless image + it's likely to make the other big stack back off considerably, leaving him more room to steal wildly)

dont think the call down is too good unless the villan is triple barreling the bottom of his range at near the same freq hes value betting....say villan opens 20%(is this reasonable?) and barrels away with a polarized range of a5+,hearts, and trash - about 55% of a 20% range contains those value hands so we really need him to be overbluffing like a mad man to hero it up.....Im sure NSB had some sick reads to make this profitable but in general I think the turn is a fold

I was railing and that's pretty much what it will have been imo.
