I think the difference between 1200 and 1700 is pretty negligible, also I think the flop bet is pretty bad unless you are ready to play for stacks. Your range is sooooo polarized to JJ and QQ, maybe sometimes TT/worse pairs and AA/KK, but just about nothing else. Nick knows this and realizes he can probably get you off of anything except TT and 88, so it's an easy bluff for him to make, and you guys are deep enough so that he will almost surely fire the turn again (meaning, if you aren't folding, I would just call here).

Three-way flops play more timidly than heads-up ones so I think the best line is to check and hope for a blank turn (on which I'd happily check again).
