-I usually reraise this preflop, but since I had no read and UTG open raised to $18 (2-4 blinds) with the norm. raising $8-15 and a cold call I decided to take a flop with position, should I be reraising here all the time without any reads and stats on the players? If so to like $65ish?

-Now I like this flop, with my range on UTG I'm a favorite to QQ (depending if he has a spade) down to 99, 47.4% vs KK, and 37.3% vs AA...I would be worried about a set if MP1 called but it seems unlikely that UTG has one...right now my guess is TT-QQ, and KK AA also likely. Whats the most profitable move here?

-Should I be reraising this flop, since I had the Ad I put him on one less draw, and thought a reraise on any non Ten turn to be a good plan?
