About the queen exchange ... was asking an IM about his opinion and his response
was simple -
"It is not a move I would expect a computer to play , but what a strong human
would play. You are reducing into a significantly superior endgame : computers
tend to keep the queen around , which might also give black some counterplay."

So , great move !
I will ofcourse be analyzing that position more - especially since I get rather
horrible b.f there ;)

Congrats.
