Hoffe is this Not a checkmate?

I meint how

12 Bxg5

White's bishop on c1 attacks g5.
It is still a forced mate after 12. Bxg5 hxg5+ 13. Kxg5 Rh5# 0-1

I See thx

Bishop can take the pawn, i.e. BxG5

12.cxg5

yeah bishop takes pawn

Bxg5

Anybody else who didn't bother to read the rest of the thread?
