MadBishop: Amazing game by Korchnoi! Totally dominating with his unique flare for brilliance!<13.a4!?> is an interesting deviation from the usual 13.Rc1 or even 13.b4!? Practically it gives white a larger space advantage, but its brilliance is that it later allows white an extra file of attack!
<13. ...a5> Basically forced to prevent White from steamrolling all over Black's queenside!
<16. ...Rxa5> 16. ...bxa5? allows 17.c5!
<17.Nb5!> The start of an ingenious queenside attack!
<19.a5!> The whole point behind 13.a4!
<20. ...cxb6> 20. ...Rxb6 just hands White the open file.
<23.g3?> Pure desperation for an attack
<26.Bxd6> Black had most probably overlooked this obvious reply.
<26. ...Nxb5> Forced.
<29. ...Qxd3?> Removing the Queen from it's necessary defence of the King, though all other continuations seem equally as hopeless!
<35.h4+> There was never really any hope for Black. The continuation is obvious: 35. ...Kg5 36.Qf6#
A truly entertaining game! A gem to the chess-world!
