What if 1... Qb8? I can't see a winning line.

1. ... Qb8 2.Nc6 wins the queen via Qxd6 Be7 Qxe7 (otherwise mate) or if Qa8 Bc2+ and mate. Very nice.

Oh 2.Nc6! very clever. thanks :)

Up to date off-topic:
Italian and Greek Championships are no longer “current".
London is not "next" as chess or is not "next" as classic. Surely it is NOT a classic chess tournament. A fraud, in that regard.

6...Ne1 is not a forced move as Ne3, Nf4 and Nh4 is also available and 10...Kxd1 is also not force as Kd3 is also available.

John,
A study composer doesn't have to give lines that are covered by tablebases. Check www.k4it.de (choose Nalimov EGTB). De endgame KnKnB against Kn is normally won for the stronger side, provided you can prevent the exchange of the bishop.
In this study white can't prevent exchange or loss of the bishop (so trying to do or prevent this gives the essential lines), but wins anyway.
By the way, if white plays 8.Kb2? black shouldn't play Nxc2 9. Kxc2 and because of his extra pawn black will lose in the end. But after 8... Nd3+! 9.Bxd3 cxd3 the pawn is too far advanced and black draws.

The short answer is that, inversely of a problem, a study merely requires an obvious, forced win, not a mate demonstration. Sometimes some variation is carried out to mate, but that is an exception.

What is nice about last endgame study is there occurs the Reti's famaous study.

You may recognize it if you start with 1.Kxh3 like me also. That's what i discovered after a long try. :) I wont give any spoiler.

Very nice study, a masterpiece, which reminds us chess is, like science, developing with its long-established tradition.

Thank you Afek,
