Jack-Jack (J-J) A troublesome hand for many, this one has a few interesting nicknames but not quite as commonly used as those for Ace, Kings, and Queens. Brothers These two male family members get along well.
The way to play J-J is almost the same like A-K, you have to play it very aggressively before the flop, because it's a very good starting hand, but after the flop in most cases this hand become very weak, for exemple if an A ok K or Q comes in the flop.
