Standard Opening 4 / Review With AI

Sub-page of StandardOpening4
Moves 1 to 10  

AI doesn't like leaving the cut at a. B9 loses about 1 point says KataGo. When White doesn't but approaches with W10, the game is level again.

Moves 11 to 20  

B1 pincers. W6 prefers for a specific measure, combining W8 and W10

KataGo thinks after B5 White should cut at a. After W6 the lower right becomes hot. An alternative for B8 is b. An interesting variation is W10 at c:


KataGo prefers this variation. Instead of W7 at B8, it ataris from the other side to form a bamboo joint, then forces again at W9. After B10, White attacks at a. Notice the bizarre double empty triangle at black+circle.

Moves 21 to 30  

Using a driving tesuji of sorts, W8 makes a hanging connection in sente so that next W10 can cut.

KataGo thinks that this is a forced sequence.

Moves 31 to 40  

The pattern continues in a one way street.

Not accordintg to KataGo: W2 can be at W6. For W8 KataGo wants to connect:


After W10 Katago thinks the ladder at b is almost equivalent with the cut at ''a'.

Moves 41 to 48  

Finally KataGo thinks both players could mix in a. If W8 then B9 continues the fighting. If W8 at B9 then B9 at W8.
