Don't open-fold AJs you nits

AJs plays much better than crappy AJo(which is early insta-muck in tough games) , because it's big pot hand. You can devastate shortstacks with high card strength but those types of hands really shine (big suited cards) with deep stacks and 4 full streets of betting. Open folding AJs is abysmal in any type of game.

When you flop something marginal (like top pair) you can underrepresent and try to win medium pots against floaters & position bullies. Nobody says, that you must fire three barrels with top pair. Play it postflop with attention to image, type of game etc.
