Speaking of cash in general, if you have a QQ hand, it's all-in without a doubt.
Now, I play it according to position in different ways.
Of course, QQ vs XX what you want is for the table not to be multiway, so you should take that into account, the confrontation should be 1 on 1.
Right from the beginning I have assumed that the QQ hand is all-in, but many times I try to concentrate on my opponent's game, and if the pot out there gets to be big (for example a 60BB pot) in general I don't go all-in and make call.
I do this to avoid variance, because in general when you are at a table you know the players, and you know very well who plays you in this way, with this type of hands.
That gives you a chance to see a flop, and if that flop, let's say, contains A or K, or doesn't contain A or K, I play differently.
Because in general if a player with AKo sees a flop where there is no high pair for him, it is certain that he will even make you a minimum bet or check.
But if the flop contains pair high, then in general you will realize that the player will try to get the most out of his hand, then you knowing it, you can make the decision to continue in the hand or fold.
In the event that it is your turn to fold, and this opponent actually played his hand as he should play it, you will have substantially reduced the possibility of losing your entire stack in an initial all-in, which you know the chances of winning exist, but also there are chances of losing.
I always say that the allin in these cases, is a way of playing Russian
roulette with a two-bullet revolver with a single bullet in its magazine, if you are lucky that no bullet triggers you are the winner.
