(;W[cm]LB[co:A]C[White A would be more common in this fuseki (see variation), but Sakai Hideyuki had a different plan...]
;B[cq]
;W[gq]C[This is one of Cho U's favorite moves, so I guess that Hideyuki played it himself to make his opponent angry :)]

;B[cr]
;W[fn]LB[dm:B][cn:A]C[Black got a nice corner, but the A-B exchange made White very thick. I prefer White's position here, but Black is keeping sente, so the result is probably equal (joseki?).]

;B[pl]LB[pj:B][ql:A]C[This was a nice move. If White answers at A, Black can cover at B (and reduce White's influence naturally).]

(;W[jc]LB[if:A]C[This move was very sharp!
The invasion is possible because Black's formations still have some weaknesses. (See variation).]

Finally White won by 2,5 points.]
