Position is power

Anntte_15 Obrestad famously won a 180 man multitable sit and go tournement playing only position, and looking at her cards only once. She achieved this by putting a post it note over the computer screen so she could not see her own cards and proceeded to hammer any opportunity to isolate weak players and play in position, betting and raising without mercy. When I found out about this it left me thinking that she must have known her opponents' range or tendencies to some degree, to be able to judge which flops to bet. I have never studied the video in full but I watched some of it and it is hard to know how selective the moves were, or if it was literally blind aggression that won it. At a recent home game we discussed the feat and tried a couple of cheeky blind raises in position. I got away with it on one occasion when I was called in the big blind, but the tired villain did not notice I raised blind! One quick look at the low card flop told me it missed the big blind's range by a country mile and one quick cbet took it down!
