C[I'd like to move out with the marked stone]
(;B[je];W[gd];B[id];W[hc];B[jc];W[qc]
C[well-timed probe; since B has played so solidly on the left, a play at A would be overconcentrated. However, the strong play at B would not kill the corner]

C[this is a compromise between A and B, but does leave a ko in the corner, which shows that the probe was well-timed]
;W[gf]TR[fc]
C[W38 finishes the capture of the marked stone; failing to move out with it, as shown earlier, has given W a territorial lead and, with no stones for B to attack, the pressure is on for B to catch up in territory]
