I think I would've played at i8 - the most-open corner - rather than immediately responding to D9.]

C[Eric\: I believe that if White plays along the 11-edge, then Black still gets something like this variation.]

This peep is a reversal, so White should respond with it.

If White plays next in {E7,E8,F7}, then White gets all of those (since E8 will be dead).  If Black plays next in {E7,E8,F7}, then Black gets at most F6 connecting to E8, and Black already had the ability to make that connection before the E8-E7 exchange (by playing E8).]
