Tournaments when you are knocked out you lose one buy-in.
Cash games you ca reload and lose more.
Cash games are far harder than tournaments, in my experience playing razz. I think there may have been bots involved at the $2-4 +, level. I started out at the lower levels and was a winner, but at the higher levels, I couldn't win, even against the outrageous chasers. It appeared I was being set up.
