Sep-15-04		Sergey Sorokhtin: NEW KASPAROV'S COMMENT!!! 34...a5? Here there were many decisive continuations: 34...Qe6 and …h7-h6 (Chistyakov), 34...Kg6 (Ragozin) 35.Be5 Qxe7 36.Qf3 Nd7! 37.Qxd5 Nxe5 38.dxe5 Qc5+ or, finally, 34...Qa4! with the threat of …Qd1+ (Kmoch, Euwe) – I tried to find a defence after 35.Qf3!, but without success: 35...Qa1+ 36.Kh2 Qb2+ 37.Kg1 (37.Kg3 Qxc3!) 37...Qc1+ 38.Kg2 Qd2+ 39.Kg1 Qe1+ 40.Kh2 Qe6 41.Ba3 Qe4 and Black wins. Denker’s inaccuracy apparently throws away the win – anyway, it gives White practical chances, which Euwe exploits simply splendidly! 35.Ba3! Qa4 36.Qd6 Qd1+ 37.Kg2 Qe2+ 38.Kg1 Qe3+ 39.Kg2 Qe4+ 40.Kg1 b5 41.Qd8 b4. For the moment Denker is equal to the occasion: it was worse to play 41...Ne8?! 42.Qxa5 or, of course, 41...Qb1+ 42.Kg2 Qa2+ 43.Kg1 Qxa3?? 44.Qf8+ Ke6 45.e8Q+ Nxe8 46.Qxa3 and wins. 42.Qf8+ Kg6 43.cxb4 Qxd4+ 44.Kg2 Qe4+ 45.Kg1 axb4 46.Bxb4 d4 47.Ba5! Euwå finds the only way to resist: the manoeuvre of his bishop to d8 with the threat of Qxf6+ and å8Q+. 47…c3. The most obvious move. According to Denker, ‘47...Qe6 was better’, but after 48.Bd8! (with the threat of Qõf6+) 48…Qf7 49.Bb6! White would have gained a draw, for example: 49…d3 50.h4! gxh4 51.Be3 Qe6 52.Qh6+ Kf7 53.Qf8+ with perpetual check. Also unclear is 47...Qe5 48.Kg2! (but not 48.Bd8? Qg3+ 49.Kf1 Qxh3+ 50.Ke1 Qh1+ 51.Ke2 Qg2+ 52.Ke1 Qg1+). Ànd 47...Qb1+ 48.Kg2 Qa2+ 49.Kf1! is right. (Sorokhtin) 49…Qxa5 (after 49….Qa4 50.Bd8! Qd1+ 51.Kg2 the terrifying threat Qxf6+!! forces Black to perpetual check) 50.e8Q+ Nxe8 51.Qxe8+ Kf6 52.Qf8+! Ke6 53.Qh6+ Kd7 54.Qxh7+ Kc6 55.Qg6+ with a simple draw. <…> 48.Bd8 c2?? Denker attaches as many as three question marks to this move and writes: '48...Qb1+! 49.Kh2 Qa2+ and …Qf7 would have won’. Let us check: 50.Kg1 (not 50.Kg3? Qf7 51.Bb6 c2 52.Qc8 Ne4+ or 51.Qxf7+ Kxf7 52.e8Q+ Nxe8 53.Bxg5 Ke6 and wins) 50...Qf7 51.Bb6! c2! (the only move) 52.Qc8! (also the only move) 52…d3 53.Qf5+ Kg7 54.Be3! Qxe7 (54…h6!?) 55.Qxd3 h6! (55...Qe5 56.Bxg5! Qxg5 57.Qxc2 is less clear) 56.Kf1 (56.Kf2?! Qc7 57.Bc1 Qh2+ 58.Ke1 Qg1+ 59.Qf1 Qd4 60.Qe2 Qc3+) 56...Qc7 57.Bc1 Qc6 58.Ke1, and the win for Black is not simple. If, say, 58...Qh1+ 59.Qf1 Qxf1+?! 60.Kxf1 Nd5 61.Ke2 Nf4+ 62.Kd2 Nxh3 there is the pretty 63.Bb2+ (but not 63.Kxc2? Nf2 and wins) 63...Kf7 64.Bd4! with a draw. Euwe and Kmoch also gave 48...Qe3+ 49.Kg2 c2 50.Qxf6+ Kxf6 51.e8Q+ Kg7 52.Qd7+ Kf8 53.Be7+?! Qxe7 54.Qc8+ Kg7 55.Qxc2, and White has a difficult position, but the computer finds a draw immediately: 53.Qf5+! Ke8 54.Bxg5=. 49.Qxf6+! Kxf6 50.e8Q+. <… www.chesschamps.com

Jan-07-05		aw1988: This is definitely not a draw. The result is 1-0.

Jan-08-05		sneaky pete: It is 1-0 and black resigned immediately after 49.Qxf6+ .. was played. The sequel 49... Kxf6 and moves 50, 51 and 52 given here are an invention, as is the result. For what purpose and by whom was this game falsified?

Feb-21-05		LIFE Master AJ: <aw1988> Was this the game that you said you liked?

Feb-21-05		aw1988: Yes. Euwe-Denker Groningen 1946, with a similar opening.

Mar-18-05		aw1988: Thar she blows! Euwe-Denker 1-0. Thanks.

Mar-19-05		sneaky pete: Yes, that's better, but the last 7 half moves (after 49.Qxf6+ .. 1-0) were not actually played.

Mar-23-05		LIFE Master AJ: <aw1988> I wish I could find this game in a book, several people have e-mailed me to tell me that the score given here is NOT correct! (See the post by sneaky pete.)

Mar-23-05		aw1988: I am not sure of the last moves, I only know it is 1-0. The game may be found in My Great Predecessors volume 2 page 91.

Mar-23-05		LIFE Master AJ: I have all four of the MGP volumes. If that is true, (I did not bother to look); send the correct score of this game, (in PGN format); and tell these folks to corrct their game score. I have helped them correct many games, usually if you list the source, they are pretty good about correcting any mistakes.

Mar-23-05		aw1988: Kasparov shows the game finishing at 52...Qd2+.

Mar-23-05		LIFE Master AJ: <sneaky, aw1988> Now I am just thoroughly confused. Are you saying that Kasparov got it wrong?

Mar-23-05		aw1988: I have no idea what the correct notation is.

Mar-24-05		LIFE Master AJ: <aw1988> Me neither ... I'm stuck.

Jun-23-06		Pawn and Two: <LIFE Master AJ & aw1988> In his book, "The Bobby Fischer I Knew, Denker also shows this game ending with 52...Qd2+.

Jun-24-06		nescio: <Pawn and Two: <LIFE Master AJ & aw1988> In his book, "The Bobby Fischer I Knew, Denker also shows this game ending with 52...Qd2+.> The same score ending with 52...Qd2+ in the tournament book of Groningen 1946 with Euwe's comment: "Hier werd de partij afgebroken en later niet meer hervat. Zwart geeft het op" (At this point the game was adjourned and not resumed later. Black resigned).

Aug-15-07		wolfmaster: 52...Qd2+ 1-0 is probably the correct score, but I have no books to verify this.

Aug-15-07		laskereshevsky: i have the tournament book, (in german language) basing on that i can confirm the game finished with 52...♕d2+ 0-1.!!!!!!!!!!! ...............HE!HE!HE!....im joking.......... the final result was 1-0......

Sep-30-08		micartouse: These two should be commended for their deeply original play in this encounter.

Jul-28-14		plang: 10 a4 ts rarely played (10 0-0 is standard) but had been used by Botvinnik two months earlier against Alexander in the 1946 USSR-Great Britain Radio Match (White won). Taimanov after 19 Qb2: "In this critical position, where both sides have carried out their strategic plans (White - to break through in the centre, Black - to win a pawn), the chances are with White. He has a concrete plan of attacking with his e- and f-pawns. wher-as Black's counter-offensive on the queenside is usually too late." Alexander had played 19..a5; 19..g6 was Denker's improvement. 23 f5? followed a similar maneuver as in the famous game Botvinnik-Capablanca AVRO 1936 but was not as effective here; better was 23 Be7!..Qc6 24 f5..Nc5! 25 dxc..Rxe7 26 Rxe7..Qc5+ 27 Qf2..Qxe7 28 fxg..Rf8 29 Nf5..Qc5 30 gxh..Nxh7 31 Qxc5..bxc 32 Ne7+..Kg7 33 Nxd5 with a better endgame.
