E 4. On the other hand, C3 and E 5 are bad, because the territory which is obtained by C 3 is too small, and the adversary would reply to E 5 with D 4, by means of which E 5 would be cut off from the margin. Of moves that are good D3-C4 are the surest, and most frequently used. E 4-D 5 formerly were the favorite moves, but the preceding moves are now preferred to them. E 3-C 5 are seldom used. All of this, of course, applies to the corresponding points in the other three corners. 5. C 4.

7. 04. Beginners would have replied to Q6 with Q5 or R 5. They attack their opponent at close quarters from the beginning, because they cannot take in the whole field at a glance. Their entire effort is to absorb the last stone that their opponent has played. When two beginners play together the battle

6. Q6. Corresponding to No. 4, this move should have been played at R 5 or Q5, but White plays on Q6, because if he played on Q5, Black would have replied at R 10 or R 9, and later White P 5 and Black O 4 would have followed, with the result that White has nothing, while Black has obtained two positions, one on O-Q and the other on R.

8. D15. The position D15D 17 is very strong, and players like to take it. This applies, of course, to the corresponding positions in other parts of the board, of which there are seven; i.e., C 16-E 16, Q3-Q5, etc As soon as one player gets a position of the kind his opponent often takes a similar position on

11. R 13. In place of taking this secure position on line R, Black should have attacked the white stone on P 17 with L 17, and in this way Black would have obtained positions on both line 17 and on line R.

and Black has the advantage, because White's stones at C 7-E 7 can only get one "Me" on the edge of the board, and later on must seek a connection with some other group. By constantly harassing such endangered groups territory is often obtained.

12. C 5. White sees that Black plays too carefully, and therefore challenges him with a bold but premature attack that gives the whole game its character.

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.

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.

26. Q9. Is very necessary in order not to surrender the entire right side to Black.

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

it up brings more territory elsewhere than is there lost. It is a favorite device of strong players to apparently abandon a position to their adversary after first preparing it so that eventually it may live, or so that it may afterward aid in surrounding one of the adversary's groups. The abandoned position often reawakens to life if the weaker adversary allows his surrounding group to be itself surrounded and taken before the capture of the abandoned position has been completed.

30. F 7.

32. K 3. It might have been better to have played at G 8. Then if Black replied at H 7, White could play at C10, and the white territory in the neighborhood of line D would be very large. Certainly in that case H3 would have been abandoned, but not M 3-M 5. Since 32 K 3 is purely defensive, Black gets the attack, and appreciably reduces the white territory in the neighborhood of line D.

42. G 6. If this move had not divided the black groups, Black would have become too powerful.
