Well this was very close,first iwas going to fold it preflop and i would have folded on the flop if he wouldn't shoved...
So i have a tagish/nitty opponet plays very good hands,very aggresive i have a note... he shoves KK,AA and a fish,i wantted to bet here to see were i am but thinking back maybe was not such a good ideea...i pretty much knew what the nit had and i was in a spot that i didn't want to get...going all in with a draw 
How to play this hand....assuming you called preflop?
Also the only thing that urged me to call preflop was the fact that there were a lot of money going in there in front of me,is it good to call in this spot with marginal hands when there are some money in the pot=> in better odds
