I would've settled the k11 corner first, see next variation.];

I might've played f2, but if I had it would've been a mistake.  ^_^

Although B5 makes Black's A11-corner group strong-enough to escape a height-3 ladder, White would be able to foil with D9.]

White should probably get d9, so that Black no longer has an escape here for height-3 ladders.]

I would've settled this corner first, to gain strength towards the K1 corner.]
