I don`t go in much for freerolls, but I do play the buyin tourneys at Abs fairly often. I`d say that there is a hardcore of decent players but a lot of fish.
Example: Last night I played in a MTT there with 273 entrants. By the first break, there were only 115 left, well over half had donked out in the first hour.
However, the game lasted another four hours after that, and the final table alone lasted well over an hour, because the last 9 players (at least) were serious people.
