There were too many variations for me.
I couldn't find anything very good for W --
I probably missed something, but
seems to be quite effective.
So let's try this and see what happens.

First feeling is cross cut; before
I had already read some of the variations of the cross cut,
but I'll study some more to make sure. Judging from Loons' response time, perhaps he also had anticipated
as a possibility before he played
