I am one who would raise pre-flop with this hand. If high cards come out (no low), chances are this hand may be good, but I'd like to eliminate the J-J-blank-blank and 10-10-blank-blank (assuming you can't get Q-Q-x-x or K-K-x-x to fold, which may not be a correct assumption depending on the other players). And you also may weed out the A-3-x-x and A-4-x-x so if a 2 comes out (as it did), you may have counterfeited those who did play for low and increased the chance of scooping even if a low is on board. What is the significant downside to raising here pre-flop?
