To further explain my point, check out this hand played by Dwan versus Elky on HS.

Obviously Dwan's hand wasn't exactly similar to yours... I wanted to bring it up because it shows his great play in a super bloated pot with awkward stack sizes much like your hand. I'm pretty sure that after he 3bet from the straddle and got 3 callers with that type of flop, his $23k bet into $100k was going to be a bet/fold. It's just a super scary bet and he knows that if anyone comes over the top given that specific action the odds of them bluffing are pretty nonexistent (but then again I don't know much).
Also, pretty lol to note Matusow's serious "wow what a call" to elky on the river after elky essentially slowrolled Tom with his "tank call". It's amazing that just a year ago and still today you have guys like Matusow who clearly have no idea about NL play in these nosebleed stakes cash games.
