In freerolls and big micro mtt tournaments,I usually use the same basic stradegy.
I however do not let it tilt me when I bust out early in these type tournaments due to a suckout.
I try to play tight at first and keep an average or better chip stack,If given the opportunity to get all my chips in early on and take a chnce I will try to double up.
But will make sure I have close to the nuts if not the nuts.
Then if I do get a double up I will tighten down and play only case hands.
Toward the bubble stages of these freerolls and micro limit tournaments I will start to play alot looser seeing alot more flops,at this stage of the tournament people to tend to tighten up.
In late stages I will Often focus alot on position and my chip stack compared to average.
Also if im not the chip leader at my tble I will begin to focus alot ore on how there handling there chips.
