Definitely don't fold flop, We have to at least call once. It sucks we are oop but we only need 30% equity to continue given price and have 38% equity vs a range of hands that has no bluffs in it. If he is just going crazy with 56dd/cc, 89dd etc are equity will improve massively so folding is going to be the worst option. Depending on his turn sizing I'd probably call another bet and fold river on a non diamond/T river since I think most of his bluffs if he has any should give up by then.  

no way am i folding that flop, i would not raise bc generally only better will call and we are flipping vs a set pretty much, but i definately want to see a turn, and ideally a river if possible. standard flop call though OP. Realize your equity

in the kindist way possible if your thinking of folding here, you need to seriously re asses how you think about poker!

It's an awesome looking flop for your hand but against a very tight range, it's actually better not to overplay it on flop. vs +AQ/sets/two pairs, yeah he can have all those but the point is that you have the nut outs and it's gonna be really tough for him to fold on later streets even if the FD completes on board. 

ok so initially I didn't really consider flatting his raise, but I guess it's the best option since I'm getting it in bad OTF... My dilemma was what if blank turn and he bets big again (very likely)? 

My deciision was to get it in because lol I haz nutz draw + top pair,, but yeah I was wondering how good that decision was vs his range..
