;B[mf]
;W[kd]C[The question is whether to push or jump. Probably the best plan is to push once more on the third line. There isn't much W can do with N15; it becomes a burden to him.]

;W[ad]C[At this point I think the intelligent thing would be to leave this invasion as a sort of ungainly, point-losing probe, and returnt o P4. At any rate, it doesn't seem that W can kill the entire invasion in one move.]

(I suspect my next move was B4, but that means I've forgotten some earlier move.) White successfully invaded at A, Black didn't get enough to be comfortable after a counter-invasion at B, and finally resigned after losing C to a shortage of liberties in the endgame. White would have won by around 8-12 points.])
