I really try hard to play my game the same no matter if it's play money, freeroll or a buy in. That said, freerolls are tough to make it with others playing very aggressive so I tend to play more aggressive also. Some times it works, some times I get burned.
You need to be selective but remember they blinds go so fast. Don't be afraid to go all in or raise often with ace anything especially suited. You must play freerolls that are fast hard. Maybe not to start but not long after. If you play tight let it rip every big hand. This is only fast freerolls, chatcard rolls aren't like this at all for example, play this normally
Most of the time, just show the opponent a winner, cuz esp. early on everyone is a calling station, no matter the board... But knowing your table/opponents tendencies helps...
I like to see as many flops as I can, taking on consideration the aspects below:
- I have the agressiveness,
- How many players there are already on the hand (I'll always take a 1vs1 situation against a weak player).
- I have a pretty hand, that (not so) often will hit a strong game (like suited, connectors, pocket pairs...).
