Subject: Art of Shogi: question

My sincere apologies if you have already seen this.

I posted this twice before, with a .gif image attached. The lack of
response leads me to conclude that no one else got it but myself.
So, I won't post .gif attachments to this mailing list any more.
Here it is with a text-graphics board diagram. You need a monospace
font, such as Courier New, to view it.

In Hosking's "The Art of Shogi," pages 252-253, Sato-Habu, Ryu-O game 1,
Paris 1994 is shown. 1.P2f P8d 2.P2e P8e 3.G7h G3b 4.P2d Px2d 5.Rx2d P'2c

Sato here played 34.S76e, and Hosking says "again not 34.Sx7e B'6g."
The "again" refers to an earlier variation where the 6th file was not
blocked. But here there is a pawn on 6d, and I don't see the problem with
34.Sx7e B'6g 35.Sx6g Px6g+ 36.Gx6g. What am I missing, please? What's
white's follow-up?

Thanks very much for your time!
