its a difficult thing to be the bubble, i try and avoid being in that position but of course we all have been several times... i take my chips amount into consideration towards the last 10 players b4 bubble. i like to stay in the upper part of average chips count if at all possible. I only play premium hands till the bubble is gone... and usually when i do this and get a hand i am shown respect for my preflop raise... thats hw i keep my blinds even til bubble... but as in all tournys i play im there to hit final table and win 1st... so no matter hw many chips i have i play my hand...
