I play proper ranges based upon my stack size and dont deviate - I dont start opening up wider or calling off lighter very much at all, certain situations call for that and too many focus on having chips and end up spewing them off. No need for us to overcall marginal hands and lose pot after pot because we can afford to.
*If we are mid game and not in the $$ yet - i play normally as mentioned.
*IF we are near the stone money bubble (9 players to go or less) and im the big stack on the table, I will start opening ALOT of hands until someone starts 3betting me because no one wants to bust before the $$ and player over fold - me included.
*If we are recently ITM i still continue to play normally.
*If we are deep ITM (30 players or less) i will open normally but start to avoid marginal call offs that will damage my stack utility -- my goal is to make the FT, if i edge pass a few spots i dont care, i am confident i will outplay my villans long term so i dont need to take unnecessary risks/flips that may damage my chances of making FT $$.
*If im the big stack on my table with 11 or 12 left and 9 making the FT -- i will open almost EVERYTHING until someone shows me resistance, because again, players are over folding because they desperately want to make the FT. Pressure is key in these spots - but, pressure does not mean doing anything stupid like shoving all in every hand.
FT play as the big stack changes DRASTICALLY -- basically we have to be the tightest guy at the table, avoid any flips that will have us dropping down the pay ladder, and we have to be VERY passive until it comes down to 4 handed play where we can really open up, and go for the win! ICM is a mother...
In a nutshell, thats it for me.
