I think at move 19 black should have regrouped via Ba6-c4-e6, Rf8-e8-e2, Ra8-e8, and kept up his material advantage. Transposing to an endgame, however, may or may not be the best option for black, because of white's two queen-pawns. Black needs to utilize the central advantage, then and hope to develop a queenside attack (in which case doubling the rooks would have been more efficient on the b-file than the e-file).

It's an instrumental piece, but it does include some whispered 'lyrics' and other vocal noises as discussed here: http://en.wikipedia.org/wiki/Carefu...

But it was Röntgen who found the X-rays, also in the mid-1890s. In 1895 he made a photographic X-ray of his wife's hand, showing the bone structure and her wedding ring. The ability of these 'X' rays to penetrate human flesh was a sensation at the time. (As if nothing or nobody had ever penetrated flesh before...) Röntgen got the first Nobel prize for physics in 1901. And two years after that they turned up on the chessboard ...

When this game was played in 1903, just about the only solid scientific fact known about X-rays was that they could pass through materials which were opaque to most known forms of radiation. Can you have an X-ray attack without a quantum-level explanation for X-rays themselves?

Of course you can. X-rays were part of pop science folklore by 1903 -- although "See through walls ... clothing ... astound people with your X-ray specs ... impress girls ..." -- as seen in small ads in comicbooks -- took another couple of decades.

Those here that advocate Black should of gone for the Q exchange on c5 may have been right perhaps.

On White's part, 22.Qc5 may have been bit of a brow-beating, but I do not condemn Borovsky for thinking ...28. Qg6 to be a good move. It puts him on to mate on c2. Little inkling would he have had of impending Tsunami, the x-ray mate on f8 brewing in Chigorin's scheming mind.
