PW[forsti]PB[Moin9]WR[1k]BR[1k]DT[2012-07-10]PC[The KGS Go Server at http://www.gokgs.com/]C[Today another review of a game played by one of our loyal watchers: Helge Böger. 
His name on KGS is 'Moin9' and his rank is 1kyu.
He plays against a friend, 'forsti', also 1kyu.

He had to make a very tough choice in a rough joseki variation. Helge specifically asked us if we could show how he could have kept the game simple, so we will focus on that. Let's see what happened.
