OK, I suspect this looks a little strange at first glance - and I know from the comments addressed to me so far that many of you observers are already shaking your heads at my play so far, and doubtless will do so again over this move. So let me try to explain how I arrived at it.
The move he made looks to me like an attempt to connect his four stones to the living group below. Since my aim is to make some kind of profit by attacking them, I can't let that happen, at least not without a struggle. For example, if I play the move at O10 which I was considering before his previous few moves, he can just connect at either P6 or P7, and it's hard to see what further attack I have, while my one stone at O10 isn't doing very much for me on its own.
Indeed, I'm no longer convinced that this would have been the correct direction to play in any case. I must confess, I have problems with a lot of the proverbs about go strategy, which make some kind of sense when you see them explained, but which always seem (to me) to be hard to apply successfully in real game situations. Anyway, by playing from the top, I seem to be in danger of perpetrating the classic beginner error of trying to make territory from my thickness in the upper right. And, when chasing an opponents' group, it's usually considered best to chase them
towards one's strength, not away from it. Broadly speaking, I am strong at the top, while he is strong at the bottom - so forcing him upwards in theory should be correct.
In any case, the knight's jump between the stones he played at moves 39 and 40 is easy to cut. The problem is, as I alluded to in my post last night, and have confirmed over my attempts to read some variations, is that my cutting stones end up being far weaker than the group I'm trying to attack, which rather limits what I can do as I have to nurse them, when I want to be attacking!

looks forced to me, but after

white is well on the run while my cutting stones look forlorn - I can probably make them escape easily enough, but it all takes too much time. (I'm not necessarily claiming that

is his best move here - but I have the same problem in all lines.)
That's not my only sequence to cut, but the other one, while not leaving me quite as weak as the above, suffers from much the same problem:

- this is slightly better in that white also has to look after O6 (it's also a cutting stone; if I capture it I have no more weaknesses), but it's easy enough for him to protect and one extra move isn't going to make my cutting stone secure.
The move I've chosen, then, is an attempt to cut white somewhere, while avoiding being saddled with a very weak group of cutting stones. Essentially, it makes miai of cutting the knight's jump, as above, or cutting the two space jump which separates O6 from the live group below. For example, if white plays the natural (to me) cut at P5, he has to deal with:

- which is so spectactularly good for me (particularly in comparison with the diagrams I gave above) that of course white won't allow it. But even white's better replies (at least, the ones I've seen), allow me to cut something and reach a position where I feel I have at least even chances to achieve something in the coming fight. For example (and I'm not claiming the following sequences represent best play by either side, there's just examples of the kind of thing that *might* happen):

Oh well. I'm done writing now - I'm sure it's mostly rubbish (as you can probably tell, I have no confidence whatsoever in my go right now), but at least it's a window on my messed-up view of the position
