I'd fold now.

Shotglass - I think c/c flop and c/f turn seems pretty standard with nearly no reads/the reads we do have. I agree he's cbetting >90%. But we are trying to unbalanced his range the cheapest way possible and I think his turn barreling range will be a tad bit more balanced but cheap enough to make that more +EV than going ahead and c/r flop. C/r flop is obv. +EV though.
