;B[jj];W[oc];B[co];W[oq]C[UC: White 2 and 4 were apparently specifically invented by Doskau to counter the 
UC: influence of a play at tengen.]
;B[jc];W[ec];B[qd];W[cd]C[UC: Black 7 and White 8 are miai, a concept which Dosaku did much to develop.]
;B[cj]C[UC: Modern professionals would probably play Black 9 higher and wider, in 
UC: conjunction with tengen.]
;W[dq];B[fq]C[UC: Black 11 is a problem move. Up to this point Black has been emphasising 
UC: power in the centre and sides; suddenly he forces White into the centre.

;W[eq]C[UC: White 12; tsuke atari is an old joseki.]
