100bb I'm folding, this deep I call for implied odds, think we can win a huge pot if we connect on the river, their turn sizing isn't that big enough, might think about folding if they went $1.80~.

I'm not too hot on the idea of calling preflop 3bets with 7-high no matter how pretty it looks (depending on the opponent of course).

As played you won't make a giant mistake by calling the turn given the odds and the fact that you're in position, but there are also some reverse implied odds potentially involved (not very relevant but possibly) so on the whole I think it's a fold.
