Ongoing Game 1 / Upper Left Yose

See Ongoing Game 1

Upper left yose. Starting position.  

This is an L+2 group, so it lives (but only just). Our task is to find the best yose for white.

BillSpight: This is a 1-point play (miai value).

White plays first.  

(Note: at also threatens Black's group with sente, but that does not help here, given the solid white wall on the right.)

Two is Bill's invention. It was proposed as an alternate defense on the page named after this corner shape. I want Five at Six! (Also, the standard defense is Two at A.)

Black plays first.
