Playing Tournaments Late Stages

I always have trouble after the first or second break in tournaments. What is the best strategic moves. I always seem to never get anything, and when is the best time to make a move all in? I have heard with ten blinds. I should consider to start moving in with any pocket pairs of 8-8 or higher A suited anything and any two cards 10 or greater. What does any two cards 10 or greater mean? Like K-5 offsuit or suited?

Google Nash equilibrium charts to get an idea of push/fold ranges.

Here is a good website for it, and its free:

Any 2 cards 10 or greater means J10, Q10, QJ. Not K5... You're in a bad position when you shove with K5 because the caller can easily have you dominated and you cant make a lot of straights with the 5. When you get really short, shoving with any pair is a good idea. Looking at the chart should help. Be agressive before you get really short. Find spots to be agressive when you get under 30 or 25 big blinds.

also I think you get pokerstove so you cn compare equity of hand ranges vs. other ranges really helps

mate, it actually depends on your stack, the stack of the other players, the moment of the tournament. It is not easy to say without that information, but if you have less than 10bb, you should be waiting for a strong hand to move all in and double up, cause it is not playable with a 10bb stack. If you have more than 20bb play tight, waiting for strong hands, and try to find good spots so send all the chips to the middle of the table. If you have a specific doubt or hand of a tournament post it that lots of people will help you

If you have less than 10bb, you should move all in whit any pair,any A or picture cards on late position.

Never consider shoving with anything until your under 10 BB's. Once your under 10 bb's you then have to think about position; on the button and its folded to me I will shove with k5, any big stack would call <10bbs with a very wide range; hands like q10 or 22, even 89s would usually. If it was UTG however its an insta fold- the 8 players in front of you will easily have a better hand, and will know you shove light.

In some articles that I've read, says if you have less than 12BB then you should be more aggressive and go all-in with all pair 55-AA and AK. And if you have more than 12BB, then you should go all-in only with AA,KK,QQ and AK.

I hope that this will help you

Any two cards 10 or greater means both cards are either a 10 J Q K or A , so for example 10J KQ AJ etc.

It depends on site where you play - I went with AA, KK, 1010 on 888poker all in and every time I lost because there is not so great variability of cards like on pokerstars for example.. In early phase you play strategically - you dont risk too much but you are trying to gather some chips. In mid phase - on buble - you play more agrresive but not insanely without sense - you need to survive the buble and if possible double or tripple your chips. In late phase - it depends on your stack - you can sit out and wait till there will be less players if your stack is big enough. Or you can push towards weak and loose passive oponents... AK is worst combination because you never know if you will hit or not - it is one of strongest combination - that is true but sometimes you can get vs more oponents:

player A: Ac K c
player B: Ad Kd (you)
player C: Ks Js

and flop can be As Qc 9c 10d Jc - flop that is nothing extraordinary on pokerstars
