A80. 1.d4 f5 2.Nf3 Nf6 3.Nc3 Dr. Baumbach, as most top postal players, is well known for his deep knowledge of the openings. I am now out of my "book" on move 3! e6 An unusual idea to support e4. I decided to play to interfere with White's smooth development by exchanging light-squared Bishops. 4.Qd3 b6!? 5.e4 Ba6 6.Qe3 Bxf1 7.Rxf1 fxe4 8.Nxe4 Be7 Black is OK here. White will soon castle long and Black will soon castle short. This will lead to an attacking game where White's Rook on f1 is misplaced. 9.Bd2 If White now plays

[9.Nxf6+ Bxf6 10.d5 O-O! 11.dxe6 Re8 is good for Black.]

9...O-O 10.O-O-O Nc6 11.Ne5 White is planning to use the Rook on f1 to support f4-f5, but this plan lacks punch as Black already has a f Rook. Black begins his own attack against White's King. Nd5 12.Qd3 Ndb4 13.Bxb4 Nxb4 14.Qb3 a5! # The key to the attack:Black will gain time for his infantry to advance. 15.a3 White cannot advance in the center by

[15.d5?! as Black wins after a4! 16.Qc4 b5! 17.Qxb5 exd5 18.Rxd5 c6]

15...a4 Black gains space on the Queenside and paralyzes the target, a3, and with tempo. 16.Qh3 Nd5 17.c4?! White is hamstrung by the Nd5; f4 isn't on, and White must forever watch out for threats of ...Ne3 or ...Nf4 and, meanwhile, Black threatens ...b5 to secure the Nd5 and later open the King shield with ...b4. So the Knight is driven out, but the King is further exposed. Nf4 18.Qg4 d5! By this stab, Black drives the White Knights from the center and further opens the White King's position. 19.Nc3 dxc4 20.Nxc4 b5! This pawn thrust breaks White's defensive lineup. 21.Ne5 The Knights must scatter as the b pawn is taboo: if

[21.Nxb5 Qd5! wins.]

21...h5! # This thrust drives the Queen to a more dangerous location for White. 22.Qf3 Forbidden is

[22.Qg3 b4 23.Nc6? bxc3 24.Nxd8 Ne2+ with a win for Black.]

22...b4 The last seven pawn moves have done their damage: White's attack is ended, and he must now tend to the safety of his own King. 23.axb4 Bxb4 24.Na2 Bd6 25.g3 Bxe5! White's most agressive piece is eliminated and Black sinks a Knight solidly in the center. The resulting position leaves White with an extra pawn and Black with all the chances. 26.dxe5 Nd5 27.Qxh5 # a3! The fatal pawn thrust. 28.b3 White has to either open lines by

[28.bxa3 Rxa3 when the King has no cover, or allow the a pawn to bite deep into b2.]

28...Qd7 Black has only to gang up on the White King with his heavy pieces. 29.Qg6 Rf5 30.Qg4 Rb8 31.Qc4 Rb6 32.Kb1 Rf3 33.Rd3 Qf7! Black doesn't mind the exchange of White's active Rook. His remaining pieces will be all the stronger. 34.Rxf3 Qxf3 35.Nc1 Rc6! 36.Qd4 The Rook was immune as after

[36.Qxc6 Nc3+ Black wins.]

36...Rc3 37.Ka2 c5! One last pawn thrust: Black protects b4 for his Knight. 38.Qd1 # Qe4!? Black also wins here by

[38...Rc2+ 39.Kxa3 but White can fight for awhile by

(39.Qxc2 Nb4+ 40.Kb1 Nxc2 41.Kxc2)

39...Qc3! I was angling for a different win.]

39.Re1 Rc2+ 40.Ka1 Rxc1+! This is what I had planned on 37. .... c5! - Black has a decisive final attack. 41.Qxc1 Qd4+ 42.Ka2 Qxf2+ 43.Kxa3 Nb4 44.Ka4 Qa2+ White resigns as

[44...Qa2+ 45.Kb5 Qa6+ 46.Kxc5 Nd3+ ends all resistance. The Pennswoodpusher, May 1994]
