I just raise/folded my flush on the turn. Wow.

I agree fold preflop. Are you an action junkie as this is only your third hand at a new table. There is no need to gamble with 76s just yet or hardly ever in this position. Then all your problems with this hand are gone.
Now either he has Ks full or AA with the good A. so 1 hand beats you the other is drawing. Call down and take your meds if he has KK.
