former World Champion who is noted for his attacking style and
his extensive knowledge of e4 openings was a challenge. I was
not going to be foolish and play the two Knights defence, a
defence on which he has written extensively. Besides, I had a
feeling he would play the Evan's Gambit against me.} Bc5 4.b4

8.dxe5 Bb6 {My knowledge of the Evan's being somewhat limited,
I head for the simpler lines that return the pawn and offer
equality.} 9.Nbd2 {Keres' suggestion, but as the game shows,
it leads to a slightly better game for Black.} Na5 10.Qc2 Nxc4

psychological move. Exchanging Queens give Black a very
comfortable ending where he might even stand better. So I was
not very surprised that Estrin plays for the attack.} 15.Qe3
Ne7 16.Nd4 O-O 17.h3 Qg6 18.f4 {The only hope for the attack
is the advance of the Kingside pawn majority. But, this
doesn't turn out well because I will have a firm control of
the square f5. The objective of the next few moves is to
exchange White's best piece, the Knight, and then capiture
control of the Q-file.} c5 {!} 19.Nb5 Rd8 20.Nd6 Nf5 21.Nxc8

invasion on d3. Now 21. ...Nxe3 losses to 22.Ne7+} Raxc8
22.Qf3 h5 {! At the minor expense of a pawn, I eliminate any
possibility of g4, which makes the development of White's
Bishop problematic. If White contests the d-file with 23.Rd1,
23. ...Nh4 leads to a winning position.} 23.Qxb7 Rc6 24.Qa6 c4
{Keeping the Queen out of play and further dominating d3.}

26.Kh2 Rxh3+! 27.gxh3 Qg3+ 28.Kh1 leads to mate.} 26...Rxh3

White resigned.} 0-1
