The craziest one was an event I backed at 2.5 in to 1.2 at closing. I have never seen anything close to this before. Just crazy stuff (that is an edge of 40% i.e. you make 40c every $1 you bet)...but you do have to be willing to do the work.
The mistake in the article and that every punter makes is to assume that events with "no information" are bad...but the person setting the odds doesn't have a secret book full of "information" either...the Russian ping pong league is rigged though.
