I took part a couple of times in Knok-out tournaments, and need to say: really exciting and inspiring feelings I had.
I played something near my simple MTT Strategy, but I couldn't beat a lot of opponents (well that rescued price of buy-in with several knok-outs).
In Poker Stars
there are a lot of similar tourneys with different buy-in. For the training I'd like to attempt tourneys till 3$
Buy the way, I want to know, what perfect time to play knok-out tourneys? When there are not so many players?
