Those are all really excellent points but I disagree with the playing super tight philosophy. I play in two or three of these a week, as well as some cheaper buy-ins just to compare and they are really not that dissimilar. I used to play freerolls all the time several years ago when FTP and Pokerstars
were still the premier online games...it seems like all the maniacs have come the ACR, BOL and Bovada
...but I have changed my playing style over time and I find that my best strategy has been to look at a lot of flops early, build a medium stack and IF I am going to come into a pot and no one has raised, put in a decent raise. To many limpers giving great odds
for people to play any two, so, you still have a few people who play any two, but you narrow the field quite a bit. The pots I do come in, I come in with a decent hand range for the position I am in.
Reading the opposition is really huge, learning what the other players habits are and how they play different hands in different positions and learn who is a calling station, who bluffs, who just pushes when they have suited connectors, ect. I think this is invaluable training for anyone looking to learn the game or improve their game, with the advantage of not having to invest any money into it. Yes, it sucks when you play a hand perfectly and you have a maniac trapped for all of their chips and they hit that ONE card on the river that can save them, but that happens at all levels. It's the training that counts, knowing that you made the right decisions, experimenting with running different strategies, learning how to shift gears at the right times, the list goes on and on with what a player can learn.
I know there is a Cardschat freeroll, I haven't posted enough to get in it to see how it is. I'm hoping when it I do, it will be a good solid game.
