I am quite sure slow play has been a topic of discussion in the past. But I am going to put my 2 cents worth in anyway. Slow play started with about 450 or so players left. The short stacks delaying every hand. I do understand why they are doing it, but this effects overall play. It gradually got worse. Playing 4 or 5 hands a level, does not cut it. You are playing for points and not poker.
This may change my earlier tourney stratedgy. I need to think about it.
