Amarande: 26 Qf5 loses immediately ... however, what else is there? I am pretty sure Ed brought the Queen out to h5 in order to try to keep the Black Queen out. How important this is is seen in the variations if White had moved the Queen to a safer square:a) 26 Qe2 f3 and White loses a piece (27 Qd1 Qh3 28 Nxf3 Nfg4 is fatal, so he must play 27 Nxf3, but there follows 27 ... Nxf3 28 Qxf3 Qxd2, etc.)
b) 26 Qd1 Qh3! and really White has had it. Black threatens f3, Nfg4, Neg4, all fatal. What can White do?
b1) 27 f3 fxg3 28 hxg3 (28 Qe2 Nxf3+ etc.) Nfg4!! and it's over.
b2) 27 Bxf4 Nfg4 etc.
b3) 27 Nf3 Nfg4 28 Re1 (hoping for 28 ... Nxf3+ 29 Qxf3 and White can hold out a little longer) fxg3! 29 hxg3 Rxf3! and mates.
Ed thus had to keep the Queen out of h3; however, the only other move to do this, namely 26 Qh4, loses a Rook (26 ... Ng6 and the only way to save the Queen is 27 Rxc7 Qxc7 28 Qh3 etc.)
Ed himself considers the losing mistake to have been 13 exd5? and it does seem that the game bears this out (White looks completely lacking in positive play after giving up the center) ...
