EmperorAtahualpa: Spectacular game!!!
Here are the notes about this game in the Dutch tournament book of the Wijk aan Zee 1977 tournament, loosely translated into English:
"The jury that determines the game to win the Leo van Kuyk prize for the most spectacular match was of the opinion that none of the games of the Grand Master group were eligible for the prize and instead gave the prize to this game, which is indeed very spectacular.
<1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nxd5 6.exd5 Nb4 7.Nxd4 Nxd5 8.Nf5 Ne7 9.Bg5 f6 10.Bxf6 gxf6 11.Qh5+ Ng6 12.O-O-O d6>
The attacking player has made his first piece sacrifice and he certainly gets compensation for it. Still, the Black position also has its resources. For instance, 13.Re1+ Kf7 14.Bc4+ d5 15.Bxd5 Qxd5 16.Nh6+ does not win the queen because Black can respond with Bxh6+ with check.
A nice continuation to consider would have been 13.Bc4 Bxf5 14.Rhe1+ Be7 15.Qxf5, but White has other plans.
<13.Nh4 Bg7 14.Bc4 Qd7 15.Rhe1+ Kd8>
....and not 15...Kf8, because then 16.Qxg6 would pose a painful surprise.
<16.Nxg6 hxg6 17.Qxg6 Bh6+ 18.Kb1 Qg7 19.Qe4>
Black has repelled the first wave of attacks, but his queenside his still poorly developed. The next modest move with his rook is a move of restrained force, as shall appear later on.
<19...Rb8 20.Rd3 f5 21.Qd5 Qf6 22.Qa5!>
This threatens 23.Re6 (or 23.Be6) Bxe6 24.Rxd6+ which would break up Black's position. The prosaic move 23.Qxa7 should also be considered here.
<22...b5! 23.Re6>
The first 23 moves were all for White, but now Black makes up for his deficit in one spectacular blow and thereby claims his share of the prize.
And now White even has to watch out not to lose the game, but he secures the draw by forcing a perpetual check.
