Well done, Baldomero. I hope 'we' still have some options for a draw. it will be
very difficult to win from the current position. Here are my analysis:
Programmes used: Hiarcs 7.32, Fritz 5.32, Shredder 3, Junior 5.0, Crafty 16.6,
Genius 6, Wchess 2000 and Zarkov 5 in four Pentium computers, with an analysis
of about 16 hours.
Three basic options for Garry K. :
A) 21 h3 (The most likely one)
B) 21 Rae1
C) 21 Rad1
A) 21 h3
A1) 21 ... Ra4 (recommended by Fritz, Hiarcs, Shredder and Crafty)
A11) 22 Rab1 Qc4
23 Qh7 Qe6
A111) 24 Bd2 Re4
25 Bc3 Nd4 (Shredder +1.01)
A112) 24 Rfe1 Re4
25 Re4 fe4 (Alternative also suggested by
Shredder +1.01)
A12) 22 Rae1 Qb2
23 Qh7 Ra2
24 Qg6 Nd4
25 Kh1 (This is the main line. Hiarcs and Fritz are
totally co-incident)
A121) 25 ... Qb3
26 Qh7 (Hiarcs + 0.23)
A122) 25 ... Qc2 (Fritz -0.03)
A13) 22 Rad1 Bf4
23 Bf4 Qf4
24 Qh7 Ne5
25 Qh8 Rd4 (Crafty +0.22)
A2) 21... Rh8
A21) 22 Rad1 Qb2
23 Rb1 Qe2
24 Rfe1 Qh5 ( Genius +0.33)
A22) 22 Ra2 f4
23 Bh6 Qd2
24 Ra1 Qb2
25 Bd4 Qa1
26 Ra1 Ra1 (Zarkov +0.29)
A23) 22 f4 Bd4 +
23 Kh1 b5
24 ab5 Qb5
25 Rae1 Kc7
26 Be7 Qb2 (Junior +0.50)
B) 21 Rae1
B1) 21 ... Qa4
22 h3 Rh8
23 b3 Qd4
24 Rd1 Qc5
25 Rfe1 Re8 (Hiarcs + 0.16)
B2) 21 ... Qg4
22 Be3 Ra4
23 h3 Qh4
24 Bb6 Rb4
25 Be3 Rb2 (Crafty + 0.33)
B3) 21 ... Qb2
22 Rb1 Qd4
23 Qh7 Rh8
24 Qg6 Bh2+
25 Rh1 (Zarkov + 0.26)
C) 21 Rad1
C1) 21 .... Qa4
22 h3
C11) 22 .... Qa2
23 Qh7 Rg8
24 Bh6 Bd4 (Genius + 0.51)
C12) 22 .... Bf4
23 Bf4 Qf4
24 Rfe1 Ne5
25 Qd5 Nc6
26 g3 Qg5 (Crafty +0.26)
C2) 21 .... Ra4
22 h3 Qc4
23 Qh7 Qe6
24 Rfe1 Re4
25 Re4 fe4
26 Be3 Bb2 (Hiarcs + 0,10)
C3) 21 .... Qb2
22 h3 Qc2
23 Rb1 Bd4
24 Rbe1 Ra4
25 Be7 Ne5 (Shredder + 1.03)
Summary.
21 h3 seems the best option for G.K. , but there is no clear danger for black
after 21 .... Ra4. Special attention deserves the line A12), where Hiarcs 7.32
and Fritz 5.32 agree. Only one of the programmes –Shredder 3- evaluates the
current position as being better for white. All other programmes evaluate the
position from a slight advantage for white to equality. No advantage for black
is sought, either.
