The other day I was talking with my brother in law about $100 + $8 multi table tournaments at BestPoker (
review here).
If I remember correctly, the 1st prize was 27K. That means that you have to win 1 out of 250 to be profitable, not considering the times you will finish in the money besides 1st place.
The is the calculation $27000/$108=$250
Seeing it at this perspective it doesn't look too hard, as long as you have enough bankroll.
What are your opinions?
