Hello Tania. Here comes my more or less ill-informed thoughts about the game.

First of all  27 ... Nc8 surprised me since it looses a piece. The alternative
27 ... Qh6 , pinning the queen, which Nimzo perhaps had planned, looses to the
beautiful attack 28 Rxd6 cxd6  29 Qxh6 Rxh6 30 Re7   and the mate at a7 is
unstoppable.

From this one can conclude that Hiarcs 27 Qe3 is a very strong move, but is it
hard to find? How long does it take Hiarcs to find it? My Crafty 16.10 needs
more than 5 minutes to fail high on it (PII 400MHz).

I tried to find improvements earlier for black. 23 ... Bd7  (to stop the
shattering of the black pawns) looked interesting. The following line is
reasonable (?):

23 ... Bd7 24 g3 Nxb5 25 Nxb5 Bg4 26 Qf4 Rf6  27 Qxc7+ Ka8

with a promising pin? Behold the very beautiful
attack that can be launched now:

28  Ne5 Bxd1 29 Nd7 (threatens Qd8 and Nc7 mate) Rc8
30 Re7 (threatens Nb6+ and Qxb7 mate) Rb8 31 Qxb8 Qxb8 32 Re8!

and again the mate threat of the two knights wins the game for white.
None of this was of course considered by the machines (?),
but it is a really nice line :)

I guess the real mistake by Nimzo was 21 ... g5. It doesn't have time
to capture the white g-pawn and double the rooks on whites 2nd rank.
Whites attack with a Bxc6 (destroys the protection
of the black king) will kick in faster. The best lines I could
find for black after 21 ... g5 was 1 pawn down and worse
positional play. But then again, I'm just a semi-patzer...

						Thanks, Ralf
