|LIFE Master AJ: GM L. Portisch (2640) -
GM E. Torre (2520); [E80]
Rio de Janeiro; Brazil;
(Round #1) / 1979.
An interesting game ...
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 c5!?;
This is a well-known gambit, Fischer used it against Spassky, (their second match); and Piket used it to defeat Karpov in 1992 in a rapid game. (In a similar line, dozens of GM's have used this gambit.)
Apparently, Torre is a specialist in this line ...
[The cousin of this gambit is:
5...0-0 6.Be3 c5 7.dxc5 dxc5
8.Bxc5 Nc6 9.Qxd8 Rxd8; <"comp">

GM H. Nakamura (2704); [E81]
Cap d'Agde CCAS Trophee KO
(R# 2.3), 31,10,2008.
(Black won a nice game, 0-1 in just
under 40 moves here.) ]
6.dxc5 dxc5 7.Qxd8+ Kxd8 8.Be3,

This is one line, it seems to be acceptable for White.
[The "Power-Book" gives the line: 8.Bg5 Nc6 9.0-0-0+ Nd7 10.Nd5 b6 11.Ne2, and White has the better game.]
With this odd-looking move, Black threatens to wreck White's Q-side with a capture on c3.
White stops Black's main threat.
[The move, 9.Rd1, is also good for White.]
Both sides continue to develop from here ...
9...Nc6 10.0-0-0 b6 11.f4,
This gains space and perhaps threatens e4-e5, to shut out Black's DSB.
[The (main) book line is: 11.b3 Bb7 12.g3 h6 13.f4 e6!? 14.Nb5 Ke7 15.Nd6, when White is clearly on top.]
11...Bb7 12.g3 Na5 13.b3 e6 14.Bh3,
This looks OK, but is perhaps imprecise.
[Probably better was: 14.Bg2 Ke7 15.Rhg1,
when White remains a pawn ahead, although Black has good play.]
This advance was hasty and wrong, better was the "Power-Book's" suggestion of 15.Rhf1! (White would still be better.)
15...Be5 16.fxe6 fxe6 17.Bf4 Nc6;

Suddenly, Fritz 12 (and other engines) show that White's edge has virtually disappeared. (His pieces rest on odd squares.)
18.Nb5 Nf6 19.Rd6?!, ('?')
This is a deep exchange sack - but it ultimately proves to be unsound. (19.Nd6 looks to be better.)
19...Bxd6 20.Bxd6+ Kf7 21.Rf1 e5 22.Bd7?,
A fun move, but the engines show this to be the losing move here. (All the boxes agree, after this move, Black is winning.)
[Probably better was: 22.Nec3 a6 23.Nd5 axb5 24.Rxf6+ Kg7 25.Be6, "<=>" with incredible counterplay for White.]
22...Nb4 23.Nc7 Rad8 24.Be6+ Kg7 25.Be7 Nxe4 26.Bd5?!,
Another move that is clearly inferior ... or less than best.
[White had to play: 26.Bxd8 Rxd8 27.Rf7+ Kh6 28.Nd5, although Black should still win.]
26...Bxd5 27.cxd5 Rxd5 28.g4?, ('??')
White missed a cool resource here.
[Better was: 28.Ne6+! Kh6 29.Nc3!! Nxc3!? 30.g4!]
The rest is a mop-up operation for Black.
28...Rc8 29.Nxd5 Nxd5 30.Bh4 c4 31.Kb2 c3+ 32.Ka3 Ne3 33.Rg1 Nc2+ 34.Ka4 Nd4 0-1
