Moves 21 to 30  

5: Too close.

7: Playing on the left side is bigger.

10: Very bad. Should play like in Variation 1.

Moves 31 to 40  

1: Now White is heavy.

3: Has to play hane at a

4 and 6: These make Black stronger, so it's better not to play them, as White maybe wants to attack with b later instead.

Moves 41 to 50  

1: Bad shape. Connecting at c is better.

2: After 34 and are 36 played, this invasion is no longer fun.

3: Small. Better around d.

6: Very bad, as it just cuts two strong groups. Has to be at e. After a black move at 6, white would just play d, as the two stones left of 6 aren't worth defending then.

8/10: Should also be at e.

9: Looks a bit slack.

Moves 61 to 70  

4: The white stones become weak now. Probably it's better to play like in Variation 2

Variation 2 (a-e=11-15)  

Variation 2: White sacrifices some stones to get thickness and sente and takes the free corner afterwards. Probably the game is close then.

Moves 71 to 80  

2: Aji-keshi. Just 4 is better.

Moves 81 to 90  

2: Maybe the losing move. f would be the Ko-Threat. Now white comes under heavy attack, but even after he lives he is behind.

Moves 101 to 110  

4 and 7: ko
