Before the flop you should raise with Ace/Jack suited. If you
get a raise back, then reraise. The reraise might get some folks out
while it is cheap to do so. Depending on the flop it might buy you a
free card by making the other players hesitant to bet into a
reraiser. A suited Ace/Jack as almost as many possibilities as
Ace/King but you have to be aware of the gap. As in:
Ace,GAP,GAP,Jack. Like almost all hands the best time to play these
hands is in late position but a raise from the Blinds can set you up
to steal the blinds or set up a semi-bluff. You want to get the other
poker players out and fussing with their chips, and cursing their
luck.
Pay close attention to the board if you did not flop the flush or
straight or at least the flush or straight draw. There might be some
dummy who called the raise and reraise with a 6/7 off suit and saw
5/8/9 flop. There might be someone drawing to a different flush than
you are. His odds are the same as yours but lighting does strike. So
if you are looking for diamonds and you see two or three clubs,
hearts, or spades hurry back to the porch. This is not your time to
run with the big dogs. All of a sudden it not about winning with the
Ace/Jack Suited but it now about saving money and preserving your
stack.
