White

21. G 2. Is played very carefully. K 3 would probably have been better. In that case White would either have played H 5 in order to save H 3, whereupon

B. F 7 W. E 8
B. K 5

would have followed, or White would have answered at K 4.

22. M 3. Two stones which mutually support each other on the margin of the board and form a position cannot be separated by more than two spaces; for instance, R 13–R 16. In that case the adversary cannot cut one off from the other. (Korschelt here inserts continuations similar to what we have shown in a preceding chapter.) Therefore, White’s twentieth and twenty-second moves are merely intended to fill territory that would otherwise fall to Black, and are not intended to form a new group.

23. H 2. The only correct answer would have been K 3, which would have separated White’s twentieth and twenty-second stones.

24. M 5. White seeks to form a connection with No. 6, which Black frustrates by his twenty-fifth move. It is of the greatest importance to prevent the union of groups which the adversary has formed on the margin, in order that they may remain weak, and require continuous defense.

The player who has the “Sente” most of the time will generally be the victor.

25. O6.

26. Q 9. Is very necessary in order not to surrender the entire right side to Black.

27. K 17. All good players agree that 27 should not have been played at K 17, but at L 17. This is difficult to understand because K 17 can be supported from both

28. H 17. This move has the effect of abandoning stone No. 4 at P 17. After Black’s twenty-ninth move at N 17, No. 4 could still escape by means of P 15, but giving
