Have you tried in Chessgames?
Searching a Nezmetdinov game
The closest I could find to what you describe is this game played in 1966. It was a Philidor, Qxb2 was played, it was a mistake, and black lost shortly thereafter.
That said, Nezhmetdinov played inaccurately afterwards, and if black had played accurately, would have made a game of it.
Maybe this is the game ( Neishtadt , Win in the Opening, Edition Olms AG 2000, Zürich)
Thanks a lot, this is the game!
And thanks for everyone who searched, especially BobbyPhisher960 who revived this topic.
I don't know why, this game doesnt appear in my megadatabase 2017, strange...
Hello,
I was impressed some times ago by a short game played by Nezhmetdinov (not surprising lol).
Rashid was white, and I remember his opponent playing Qxb2 in the opening and being punished.
I thought it was on a Caro Kann, but i am unable to find it.
Sorry for so few informations about this game.
Maybe u could find it?
