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. ;-)

Game 4: ralph(b) alwin(w) b+1.5

Move 7 should have been an approach in the lower left corner.

Moves 1 to 10  

Moves 11 to 20  

Moves 21 to 30  

Move 1 is a good invasion point and 2 is the wrong answer. White 3 would have been better. Game is now favourable for black.

Moves 31 to 40  

Game 6: ralph(b) alwin (w) b+ resign

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

Moves 1 to 10  

Move 5 at a or b would have been interesting.

Moves 11 to 20  

Now black pushes from behind. No! No! No!

Moves 21 to 30  

Number 9 is a risky pincer and leads to a tough fight.

An interesting cut:

Moves 61 to 70  

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

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

Moves 1 to 10  

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.

Moves 11 to 20  

Game 9: alwin(b) ralph(w) b+
