Why I guessed the way I did.

Ok, Harlequin, everyone has made their guess...

Well, OK. I shall put it into hide tags, for the case that someone wants to take a stab at it for himself.

Fascinating. Thanks for the interesting challenge, Harlequin.

I would like to discuss some positions from the game.
The first was this:
Black now played the two space jump. My feeling is that this is not good, because Black cannot comfortably counter-pincer afterwards due to the white support from the left corner. I think that it is better to either directly approach the lower left corner or to play the kosumi (O4) to settle quickly.
I am absolutely not sure about this, and it might be a question of style, but I would be interested in hearing arguments for the two space jump.
The next thing was more severe, I think.
Here, Black peeped at Q5. I think that this is bad, because Black could have settled much better by attaching in the corner:
The peep destroys that option, and its only function is to fix the thinness of the two space jump. It would again be better to approach the lower left corner directly.
What do you think of this?

I think that I see the logic of the peep. The overarching plan, of course, is to counter-pincer. ( Whether or not that is a good plan is another issue. ) White's R6 is, IMHO, too small, for it does not adequately pressure black. If black sees R6 as I do, he concludes that his group is not in danger and can then tenuki to the lower left. But before tenuking, he must take care of one last possibility: he must prevent white from pushing through the two-space jump. He does this in sente, and then he can tenuki. It makes sense, given his goal of the counter-pincer.
Furthermore, he does not mind the exchange of Q5 for R5. With R5, white is over-concentrated. After R5, tewari analysis suggests that R6 is misplaced. It looks like this:
But if white were allowed to reposition his R6 stone, he would want it like this:
In summary, I think white's R6 was a minor mistake, and the peep was an attempt to exploit that mistake. It is a pity that it was done in pursuit of a dubious goal.
