Game Number 30. 'Double Cross' Opening

A simultaneous exhibition game. Black: Club player; White: D. Oldbury.

Move: 9-14 23-18; 14-23 27-18 (I handicap myself by choosing an opening which is strong for Black); 12-16 18-14; 10-17 21-14; 11-15 (less well known than 6-9, and perhaps played for that reason) 24-19; 16-23 26-10; 6-15 22-18; 15-22 25-18; 8-11 28-24; 11-16 29-25 (you will observe that almost every move I make in this game is towards the centre); 4-8 25-21 (an exception, and significant); 1-6 30-26; 16-20 24-19; 6-9 26-23; 8-12 32-27; 7-11 31-26; 11-16 (an important situation which the student should grasp well) Forms Diagram: White to move

Continue: ... 14-10 (vital); 9-14 18-9; 5-14 26-22; 14-18 22-15; 2-7 10-6; 3-8 15-10 (this also); 7-14 19-15; 16-19 23-16; 12-19 6-2; 14-18 2-7; 8-12 7-10. Drawn.
