lol how did you guess? well where does the King go? J' adube, J' adube I didn't see the check!

What about Nf4 ch? opening the file for the h-rook and making the diagonal h3 -> c8
of the Dowager more effective?

I'd play ...Kf7, but then I've been retired for so long I've probably got it wrong.

Correct. Its not hard to see if its given as a ''puzzle'' but in a practical game would be tricky

Sadly this is another example where the startling combination isn't the best move; it's all very well if white goes queen-grabbing, but what if he does not? Still very well worth knowing such things are even possible.

here is one that is even more difficult (and hopefully more accurate!) white to play
2738

Ok, Michael. Some un-PC software assisted analysis.
(a)Try 1 Na5 Qxh1+ 2 Kd2 Qd5! and Black wins. (Na5 can only work if b7 is undefended. So point taken)

(b) Try 1 Nd6 Qxh1+ 2 Kd2 Qd5 3 N (say d) x f7+ Bxf7 4 Nxf7+ Kc8 and I think the best white has is a draw by perpetual check. If 5 Rc1 than one of the N's goes to c6 and Black wins.

(c) Try 1 Rc1 Qxh1+ 2 Kd2 Qd5 and again no killer.

So for now I am stumped. Looks like a different first move, or I am missing something in the Nd6 line. Need to look at it in daytime....(This is why Baron is an FM and Adamski is a patzer.)

The puzzle is reminiscent of one of Paul Morphy's games (maybe v Duke of Brunswick) where he sac'ed 2 R's. James P. was Morphy white here?

Sorry for the Nd6 answer, I should have said Nb6 as this leads to a quickish win if black decides to be a ravenous glutton and pick off the two rooks.

1.nb6 qxh1+ 2.kd2 qxa1 3.nxf7+ bxf7 4.bc7+ kxc7 5. qe5+ kxb6 6.qc5+ ka5 7.b4# And its all good in da hood !!

Its Cohn vs Chiszar 1944 which oddly I can't find in any sources other than How to Become A Deadly Chess Tactician

This is a famous position that occured between not so famous players in Spain in the 1930's.

There's quite a lot of discussion of the history of it on Tim Krabbe's site. Caruana won a vaguely similar position not long ago.
