FINAL SCORE:

alwin ralph

== 4 : 6 ==

Game 1: alwin(b) ralph(w) b+

The marked move was questioned by sensei fabi. But a quick research showed that this move is in fact played in pro games sometimes, although it was not very successfull most of the times. ;-)

The combination a,b,c would have been a game. But see the different actual continuation.

Black uses his overwhelming center influence to reach a balanced game.


Game 7: alwin (b) ralph (w) w+ resign

Now a questionable move 2 on the left side. A shimari in the lower right would have been the way to go.

The attachment 6 should have been under the black stone.
