One thing I've noticed some players do is just fold fold fold even though they are down to like 3 blinds. I've seen players fold on SB even though they are down to sometimes less than 1 BB.
What?
Call with ATC in that situation. Even if you get AA, if you are down to like 2 BB and double up, that's not really gonna do you any good.
If you are right on the bubble, then ok I can see folding junk and hoping you back into the money,but most times, you gotta fight for your life rather than just bleed out.
And once you get to the final table where the stack to blinds ratio is small, it comes down to luck. If you are lucky enough to get QQ+ at this time, you will probably last longer. If you don't get a great hand, you will have to shove with ok hands. Try to be the first one to shove. If someone shoves in front of you, then tighten up.
