A few comments, not necessarily correct:

- I think you should capture the laddered stone right away. Leaving it around leaves you unequipped to fight in the lower left corner, which you proceed to do with your pincer.

- Locally, I think jumping to C8 is advisable. I can't help but feel your

is neither here nor there - it doesn't enclose the corner, and after you exchange

and

, your

stone loses a lot of its value by being completely undercut.

- I still think capturing the ladder stone is important. You can't start a running fight in this area and not have black be able to pull off a ladder breaker.

- I think black should pincer before jumping.

- Needless. Strengthens white.

- Too slow. You have no need to protect those two stones too strongly; they can be sacrificed. This is another opportunity to capture the ladder stone.

- IMO, sealing in is better for black. Make you flail for life in an enclosed area while loosely connecting all of his groups and gaining massive influence.
Ultimately, I felt white was behind by the time he played

, so I feel the problem must have come either from the joseki choice in the top right (it's not what I would have played but I can't say its wrong),

, or

(inclusive-or).
