When i get down to around 6 or 7 BB's i'm pushing all-in any Ace or any two painted cards... If the blinds are say 500/1000 and i have 7k..it's going all-in before the BB gets to me.. preferably UTG, hard for anyone to call there. However hard it may be to bet, it has to be done .
There comes a time when you cant get antie down, so that your bet wont make a difference and you get called on all sides, you have to draw the line and say, "this is where i make a stand "

A bit like 'Custer at the Battle of the little Big Horn'....mind you, it didn't do him much good
But you all ways have two cards and you have to know that to win, you have to be aggressive .....here comes the cavalry !!
