This is a discussion on Cards to go all in preflop with within the online poker forums, in the Learning Poker section; In all the games I played I had good cards which I went all in and the worst hands I knew how to win, that's
It is not always profitable to go ollin with such cards. But that's your business. You have an aggressive style of play. If you are lucky, you can even win the tournament. I play like that sometimes, too. But I think that it is better to use this style at the beginning to collect chips. Then, if you do not fly out at the beginning of the tournament, it is more profitable to play only ready-made hands and even the Flash draw is better to discard, so as not to fly out to the prize zone.
There are situations you should go all in literally with any 2 cards.
I guess you are asking about MTTs because in cash games all ins pre flop it's not a common play. MTT are more of a game of dynamics it's not more kill based game like cash games IMHO.
Your range can't be static in every situation , we must narrow/widen out range in open shove / 3bet jam situations given many factors like: opponents , phase of the tournament , effective stack and position of the initial open raise and many others.
Poker isn't this simple. It depends on many factors such as effective stacks, ICM event structure, how tough the opponents are and many other things. As Daniel Negreanu says, "you are almost always correct to get it in with AA or KK."
However, if we are short-stacked, then we may want to have a much wider range due to so many chips in the pot in ratio to our remaining stack. I recommend checking out the cardschat.com 30 Day course; they even discuss what hands are recommended to go all in on when short-stacked.
