I haven't looked at this position for awhile, but it looks very interesting!
My original intention was to play a moyo game. A moyo is more difficult to achieve with white (that is, without giving up the advantage to the other player), so the moyo has to appear "naturally." This can take several forms. For instance, I can keep offering exchanges (in particular, corner or side josekis) where I always seek to take the outside. The other player may wish to resist this by insisting on taking the outside himself, but the idea is that this would be an unfavorable exchange for him. In other words, if he were to try taking the outside, he would put me in the lead, even though I wouldn't be able to get a moyo.
Another way to get a moyo "naturally" is by attacking (and, hopefully, chasing) a weak group. This is the approach I hope to utilize in the present game position. I will attack the group on the left and also, hopefully, the cutting stone
. A great outcome for me would be if I could force black to live small on the left side or to force black to run with that group into the center while I build influence around it on both sides.
For my
move, I also had the choice to play the following.

I rejected this choice because, although I could attack Black on the left side more severely, the cutting group
would become significantly stronger than at present (which would also significantly reduce the aji from my two stones at the top) and so would make the cutting group almost impervious to attack.
Given that I did not play at G13, Black needs to decide if he can afford to play there himself or if he has to defend on the left side, first. Stated differently, if Black plays G13 next, will I be forced to connect at F13 or will I be able to hane at E11 with profit?
