I'm sure I can defend... B(4,-5) an infinite board opens up so many king walk possibilities!

@Vickalan, who do you think is up in material? I have taken his queen, but he has taken more overall pieces.
After 17.Qx(2,4) (diagram pending), and without comments about positional strength, it looks to me like the bishops and pawns cancel out. The guard also cancels knight. So the lost C+H might be a few pawns (4?) more than the lost Q? But this is just guestimating.
