During a poker tournament, our stack will almost always go through several variations, one time you'll be deep, another time you'll be short. Your survival in the tournament depends on how well you work with each type of stack, so in this article I'll briefly discuss my opinion on strategies according to stack.
Between 3 and 10BB (Short stack):
We're in a more delicate situation, our stack no longer works for restealing the raiser, as we'll be paid off the vast majority of the time. At this point, the best strategy is to wait for a reasonably good hand with good equity to go all-in. I've seen players make big mistakes with this stack, and this will affect your ROI at the end of the month. Be patient and don't go all-in with mediocre hands. Several times I've been all-in with 2 or 3BBs and busted the tournament.
Between 12 and 20BB (Medium Stack):
We're not in a bad situation, but we're not in a good one either. This stack is perfect for restealing. We need to analyze the opponent who is raising, see how he is playing, the % times he raises and steals and apply a rebet when the factors are on your side, you don't need a strong hand when the opponent is playing very aggressively, because the difference between the range he is raising and the range he will call on your all in is so big, that sometimes shoving any two will be +ev.
Between 20 and 30BB (Medium Stack):
Now we have a slightly calmer stack to work with, we still can't make all kinds of maneuvers, but we already have room for greater playability. With this stack we can make more raises in position, we can see some flops and we can also make some 3-bets or 4-bet lights. Your strategy here is to try to aggress on the weak players, to play more post-flops against those who can't defend themselves very well.
30BB or more (Deep Stack):
We've got a very quiet stack, so we can make any kind of play with this stack. Do you want to play tight? Do you want to play loose? Do what you want, your stack allows it. I don't see why you should play very tight with stacks of 40 or 50BBs, because the hands that will fold to you with that stack will almost never be AA, KK or AK, but rather 68s, TJs and other connected hands. Normally with this stack you put yourself in a very bad situation when, for example, you raise AA, get called and on the 975 flop you Cbet and your opponent raises you, while with 78s you Cbet on the AK2 flop, if your opponent shows any resistance you just turn the hand off and lose only the value of the Cbet. Remember that with deep stacks you have to work much harder post-flop than pre-flop.
The basis for playing tournaments is knowing how to work your stack, study this a lot.
That's all for today, big hug!
