Beats the game live, but loses online?

[LockLow34]

I think it's time to face facts: I can't win online. I've played online off and on for the last year and my results have been mediocre at best. Conversely, my results from playing regularly live (3/6 and 5/10, mostly) show me beating the game for >2BB/hr. (yes I have the detailed records to back this up)

Do others have this experience?

Anyone care to speculate on why this is?
