Interpoker was running a 2 for 1 special, I don't know if it is still going on. Win an entry into the main event and they will give you and entry in to the $500 or $1500 (not sure which) buy-in event for free.
I'm not sure they regularly televise the small buy-in events??? Ive seen: Limit, Raz, PL Omaha, and the Main HE event....Hmmm
