1..e5
<On this, and even more on the third move, I an say that I mainly played it because I hadn't played it for a long time.>

5.d4
<5.c3 can, after 5..a6 6.Ba4 d6 7.d4 Bd7 lead to a recognized line, where however early castling is not seen as White's most energetic choice (after 3..a6 4.Ba4 d6 5.c3 Ne7 6.d4 Bd7)>

8..0-0
<Here White can lose incredibly fast: 8..Nxd4 9.Qxd4 Qg5 10.Nc3?? Nh4! But good is 10.e5!>

10.Bxc6(?)
<Now Black gets good "opposite-coloured" attacking chances. The Yugoslavian Encyclopedia has 10.Be3 Kh8 11.Qd2 f5 and a claim for initiative for White. In a simul game (!) in Dallas 1974 I played the more energetic 10..f5, but how would the theorists know that? Medina-Sanz, Las Palmas 1978, saw 10.Re1 f5 11.exf5 exf5 12.Be3 Nce5 13.Be2 Qd7 14.Qd2 Kh8 with somewhat equal play - but after 15.f4(?) Ng4 16.Bxg4 Bxg4 17.h3?? Bxh3 decisive advantage for Black. The black setup is probably one that most people do not know and therefore underestimates.>

13..Bb7
<A lovely diagonal. After 14.exf5 Rxf5 it is difficult for White to put a cork into it (Nd5), and Black will get good attacking chances. (But 14..Nh4 15.Nd5 Nxf5 is somewhat equal).>

14.Rae1(?)

17.Qf2?
<An oversight in a bad position. Natural would be the attack 17.f6. I had considered 17..gxf6 18.Bxf6 Rxf6 19.Rxf6 Qg7, but this falls upon 20.Nxe4! (20..Bxe4? 21.Rxe4 Qxf6 22.Qd5+). Very strong is 17.f6 d5! 18.fxg7 Rxf1+ 19.Rxf4 d4, e.g. 20.Nd1 e3 21.Qe2 Qxg7 22.Bf6 Qg4. Or 20.Rf8+? Rxf8 21.gxf8/Q+ Kxf8 22.Qf4+ Nf7 23.Bh6+ Ke8 24.Nxe4 Qc6 25.Nf6+ Ke8 winning.>
