Challenge: Playing the $5+1s blind

[Chiron]

I bet my friend $25 that I could maintain a positive ROI at the $5+1s playing with a post it note over my cards.

So far I've played 2... 8th place and 1st place. I have no idea how I pulled that 1st off but it was [censored] hilarious to go over the hand history... For example I folded KQs on the bubble but then pushed 24o on the next hand!

Anyone else try this, or want to complete the challenge alongside me?
