Hi to all CCC members!!

I was just analizing a very fine chess game.

This impressive game was played and won by Grandmaster Miguel Najdorf 69 years
ago. The game was really impressive. The great vision by Nadjorf and his
impressive atacking style in this game was absolutely deep and so beautiful.

I recommend to all the people that look this game and confirm why is the game of
chess so beautiful.

The are very spectacular moves made by Najdorf, that many programs today cant
find.  Look carefully :

After the mistake by White 9. Ng5?? Najdorf find some great atacking moves to
win the game. 10.Bxh2 and Ng4 are not so difficult to find for a program, there
are very natural atacking moves... But look after White played g3.  After the 13
move of White (g3), there are a great atack, that almost all the chess programs
cant see!!!!

After g3, Najdorf played the brilliant Qh5!!, not only taking to their queen to
the atack, but demonstrating that after the natural defence Kg2 ( and preparing
to the rook to go to h1 square defending the position) the black pieces still
can continue with his attack.

There are not many programs that can play Qh5, because  programs think that
after Qh5 and the natural one moved of White pieces Kg2, the attack has left,
the attack of the Black pieces has disapeared.

What program?  What program can find that after Qh5!! and the natural move by
White Kg2, there is an spectacular sacrifice move Bg1!! that it assures the
victory to the black pieces.

Ok... After the incredible Bg1, White plays Nxg1, Qh2+ and the King go to the f3
square but.... How to continue with the atack???  Is there still atack???

Indeed, very very deep for a chess program.........

But clear!,  Black pieces come again with a wonderfull move.  Najdorf sees the
decisive e5!! and go for an unstoppable atack

Great Najdorf !!!!!!!!  Great game!!!

Look all the game please, and show me which program is able to find Qh5, but
finding the sequence of moves that Najdorf found later to continue with the
great offensive.   (I think that Hiarcs is the only program to find this great
sequence after a long time !!!)




Here is the beautiful game :  (with 4 impressive sacrifices!

to win the game!)
