Ah, well, of COURSE 26...Bg7 is stronger. Especially when it is followed up by a
move that gives you a forced Mate in 8! :-)

27.a4 is a terrible blunder. After forcing 26...Bg7, Chessmaster 9000 cannot see
an easy win for Black after 27.Ng1! (this is on a P4-2.4):

I still think that 26...c5+ is the "stronger" move.
