He mentions this position as equal, while the truth is that white is in deep trouble after 15...Rg8 (most probably losing by force). [...]
You are right. Same error in
Kaissiber #32 (2008), p. 36: "12. Nc7+ Kd8 13.Nxa8 Qe3+ ist sofort Remis." After your recommendation 15...Rg8, a modern engine like Stockfish DD has no trouble finding 16.c4 Rg3 17.Ke1 Bg4 18.d4 Qc6 19.Qd2 Qxe4+ 20.Kf2 Nd3+ 21.Kg1 Ne1! 22.Kh2 Bg7! -+ and the myriad of other complex tactical variations necessary to force a win for Black.
Kaissiber #32 appeared in 2008, the engine used for the analysis was
Rybka 2.3.2a, run on my old Pentium PC. Still, I think a human should indeed understand that Black is better in spite of the fact that he is a rook behind. So yes, mea culpa. Shaw has just quoted older analysis, without crediting.
A better excuse is that 12. Nxc7+ was "at least" a draw, so it was obviously worse than 12.Qf3 which I looked at in more detail. By the way: the recommended main line in Kais. 32 was Maurits Wind's idea 12. Kc3!?, a move ignored by Shaw. And, not to forget,
Kaissiber #32 advised against 9. Nd5. Our choice was 9.d4!. - On p. 114 of his work John Shaw writes:
Quote:This line [9.d4] could be dubbed the Bücker variation as the German analyst has published a lot of analysis about it. I believe the man himself called it the "Triumphlager" variation, but I can't see that catching on.
Shaw is wrong, I never proposed such a name for 9.d4. The article published in
Kais. 32 was titled "Am Triumphlager des Königsgambits", using a term coined by Tartakower: he joked that Spielmann's article "Am Krankenlager des Königsgambits" would have better been titled "Triumphlager", because Spielmann presented mainly his wins with the gambit.
