I don't know if there is a "Winning" move for White if Black defends and
counterattacks all at the same time? Tough position! I think Spassky was
betting on that!:)
How deep do you think Spassky went? Bronstein just fell apart in "Shock" when he
saw 15.Nd6!? and blundered with 15..Nf8??
Good Work Roy!
Terry
P.S. Do you or anyone else have the 1960 postmortem on this game?
I'd like to see it posted:)
I read it somewhere years ago and don't have here. I _do_ remember that 15.Nd6!?
was a "Trap" laid by Spassky. I don't remember what Bronstein should have
played? Not 15..Nf8??;~)
