19. cxd4
Equalizing.

 
19... Qb6
! That's four hits on d4! Korchnoi now threatens to win a pawn!

 
20. Qc3
I don't know what else could be played, as the threat of 20...Nxd4 with an ugly fork could not be tolerated.

20... Nxd4
Black claims his prize!

 
21. Re2e7
Here is where it gets interesting. White has been pushed around for far too long, and delivers a threat of his own at f7. Black must eliminate this threat.

 
21... Rxe7 22. Rxe7 Nf5
! And now for the REAL fight. White has a ton of ammo directed at black's king, and at f7 in particular. Black plays 22...Nf5 to attack the white Re7, but more importantly to clear the d file for his rook.

23. Rxf7
!! This move is so subtle, yet extroidinarily strong. White threatens 24. Rxb7 winning the black queen. This move ends up being white's saving grace at the end of the game.

23... Rd1+
Of course, black sees the danger regarding his own monarch, but CONTINUES TO ATTACK! In this position, the board appears to be total offense by both sides. Defense? What is defense?

 
24. Kh2
White has been a step behind the whole game. If he can just hang on and weather the storm he will have a very explosive powerful counter punch. But can he hang on?????????

 
24... Qd6+
?!?!?!?! This move just looks and feels so right, but according to Fritz loses the game for black! I won't bore you with a thousand lines of Fritz variations, just watch as it plays out:)

 
25. g3 Ng4+
! White can't take because 26. hxN is followed by 26...Qh6 27. Kg2 Qh1#.

 
26. Kg2 Nh4+
! Korchnoi continues to go all out by sacking a knight to strip away white's defenses.

 
27. gxh4 Qh2+ 28. Kf3
Forced.

 
28... Qxf2+ 29. Ke4
A very ugly move, but it had to be made. If 29. KxN, then forced mate in 3....(29...Rg1 30. Kh5 g6 31. Kh6 Qxh#).

 
29... Qe2+
Man, black MUST have a mate in here somewhere! This is the 7th check in a row!

 
30. Kf4
White is DYING for just ONE TEMPO!!!!!!!!!!!!!

 
30... Rf1+
BRUTAL! Black is just hammering the white king! That's eight consecutive checks!

 
31. Kg5
Run, Forrest.....RUN!!!!!!!!!!!!!!!!!!!!!!!!!!!

31... h6+
Check number NINE!

 
32. Kg6
White is now hanging on by his fingernails! He has FOUR hits on the dismal g7 square but he just can't catch his breath to do anything about it.
