Kill-all Go in Insei League

We will not have handicap division in March.
Instead of it we will practise at Kill-all Go:
The rules are as in regular Go, on a 19x19 board, but Black is awarded
17 handicap stones, using free placement (Chinese rules with 9 stones
handicap and after that W passes). If White can obtain a living group,
she wins, while if Black can prevent this, he wins.

17 stones are chosen based on the experience amongst professionals
that this amount gives White a roughly 50% chance of success.

When players of different groups play this game, the number of
handicap stones must be changed: 1 stone per group.
For example, A group insei must kill E group insei on 13 handicap, but
live with the same opponent on 21 stone.

2 games per person with different colors: one with B, second with W.
Time control: 10 min +30 sec, 5 times
Free registration, without additional entry fee.

We played this game in our Korean Baduk School and I am sure, it helps
you to improve the reading ability and shapes flexibility.

P.S. Still there are 2 empty spots: one in B, another in D
