Practical Endgame Test 5 / Attempts

[Diagram]

White to play and win

(Diagram copied for your convenience.)


Arno: my try.

[Diagram]

Arno's analysis

I argue that the a-c points are miai. Therefor White should start at one of the d points.

[Diagram]

Arno's attempt

Dave: What if B4 is played at B5 instead? Is it jigo then?

Arno: yes, looks like it :-(

Arno's attempt (continued)

... and White wins by 1 point.


Arno's 2nd try:

[Diagram]

2nd try

Bill: What if Black does not reply in the bottom left corner, but plays on the top side instead? E. g., B9 instead of B8.

Arno: if Black plays B8 at W9 then White answers with W9 at B8. Mutual damage. Eventually either Black answers on the lower left, or White connects to WC then answers Black's play at the top. In both cases W+1.

2nd try (continued)

Again W+1.
