My first problem. I liked studying this in the review and even in the review I nearly missed what I think is correct direction of play. Please comment on this if you can find ways to improve the problem!

(;B[ln]B[ln]C[RIGHT];W[kl]W[kl]C[I think this is best because: It makes a huge moyo for black, an invasion will be difficult, and makes white's floating group very weak and It's sente? white will run?]
(;B[fc]C[This approach is simplest I thinkRIGHT])
(;B[cf]B[cf];W[ch]W[ch]C[an approach on this side? But then white gets an enclosure and pincer in one move])
(;B[jc]B[jc]C[I don't think this is good: 1. Not sente. 2. Black's shimari face is in the wrong direction, so the framework is flat.])
