Well yesterday I finished ITM at the CC freeroll and WAS in the top 100 in the US Freeroll until I had to be a mom (priorities, priorities, priorities). This technique is really effective in the 180 person .COM freeroll. As many of you have said, don't play the first 20 hands or so and about half the field will be gone. Don't worry about missed opportunity, when you have the nuts there will still be plenty of 'aggressive' players willing to hand over their chips. Be really, REALLY careful of multiple players going all-in. Mostly likely I will throw it away. Pocket pairs do great in heads up, but in a multi-way pot your odds
drop like a lead ballon. If you have a PP and someone goes over the top, they most likely have AK, AQ, KK. I usually have the mindset that I am going to have to dodge an Ace. The deciding factor is stack size: if you call and lose if you are taking a major hit, pass. If its only a minor flesh wound, call.
When you get to the second table, it's time to change gears. You have preserved your stack, been selectively aggressive and hopefully have been adding to your stack. Nice-nice time is over, time to go for the throat. Time to start using all the tricks you know. Start stealing from the button and CO position. Outplay your opponent post-flop, take away pots on bluffs. Play the suited connectors. The whole 9 yards. In an unopened pot if you have any PP put in a stiff raise. If you hit your set them up for a check raise on the turn. They will call. Everyone at this point is going to be playing really tight and trying to hang on.
Like I mentioned, this is really effective in the 180-225 .COM and .NET freerolls. I like the 180's better since 1st and 2nd will get a pass to round 2. In the .NET only top finisher gets a pass to round 2.
I also like using the .COM and .NET as a way to add more tables. At first I had trouble with two tables, now I am quite comfortable playing on 6. I think that's enough. But to me, this is a cheap way of getting used to multi-tasking. I guess you can learn to multi-task in a money game, but I think that might be an expensive way to learn.
