On his blog he talks about having other players play on his account: I also had a friend of mine who was in town for the weekend 6-8 tabling 50NL shortstacked. He got me a ton of VPPs and made somewhere around 80-100 bucks, we obviously did it for the VPPs
Here he says a friend played in the 20KFR: ** My buddy took like 400th out of 4k+ people in that 20k FR for me today while I was out, for a whopping 12 bucks. I didn't realize how bad this thing paid out, so from now on we only are going to do the sats for the Supernova 50k FR, and play in that.
Here he talks about taking action from a friend, railing him and giving him reads over a microphone and flipping to gets VPP's: Tonight Hokie needed to make Platinum. He needed to do about 475 VPPs in like 3 hours so I took half his action on the 110s and railed his
Here he implies that he has a buddy play for him to hit his goal of 500 VPP's a day: On VPPs. I'm probably not playing tonight, so I'm back about 700-800 vpps from my 500 a day goal throughout the month. My 6 max buddy was supposed to play this weekend but he's been offline for the last day or two (extremely surprising, our sn's are never offline).
Here he says he got Platinum thanks to a buddy: I have platinum on Stars already, thanks to my 6 maxxing buddy. Took a bit of a downswing, but we'll both ride through the variance.
Here he talks about SuperNova thanks to his friend: So yea, that and supernova, life is fun. Luckily I "have a little help from my friend." Still need like 10k vpps in 4 days, hoho.
