KQ in the SB preflop and there are 5 ppl in the pot at a loose post and preflop table: 3 of which i know will call a standard(3-4BB) raise with Ax, 1 who is VERY tight and weak, and another who just sat down. Do you think its more profitable to a)make a standard raise and hope theres no ace (which there probably is) b)make a BIG raise and try to isolate c)limp d)any other suggestions?

(It seems as though limping would be more profitable than a standard raise in this spot. Is this correct?)
