Everett: A classic battle between "The Walking ECO" and the man who had no need for it.
8..Nxd5!? is a TN, though those who wish to try something similar but different are welcome to see if <8..Nxe4!?> creates problems for his opponent.
<12..0-0> is also a viable alternative, to see where White puts his Q and K. The e7 square may not be the best for Black's Q.
15.0-0-0?, fighting fire with fire, could have gotten Furman burned if Bronstein found <17..Rac8 18.Kb1 Rfd8>, tactically covering his d-pawn while centralizing his heavy pieces. Black seems to have a strong advantage here, with heavy pressure on White's K.
After 17..Qc5+?, White is able to force the Q-exchange, and poof goes much of the play, and then 25..Rd6?! instead of <25..c5> does not create any opportunities.
<34..Ke7> seems to be the last chance to hold, but things were grim by then.
