1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 {To play such a move in correspondence
chess is not a great idea. This line could work in a tournament game, due to
the constraint of available time. However, in correspondence chess it is a
completely different world.} d5 5. exd5 b5 $5 6. Bf1 $1 {This paradoxical move
is the best in the position. The idea is to keep g2 pawn defended so that Qxd5
can be met with Nc3, developing with a tempo.} (6. Bxb5 Qxd5 {is completely
fine for Black.}) 6... Nd4 7. c3 Nxd5 8. Ne4 (8. cxd4 Qxg5 9. Bxb5+ Kd8 10. O-O
Bb7 {The position remains unbalanced and complicated.}) 8... Qh4 9. Ng3 {
This move not only saves the knight but also blocks the h4-e1 diagonal. Now
Bg4 can be met with f3.} (9. d3 Bg4 {is not so easy to meet.}) 9... Bg4 10. f3
{The bishop on g4 is attacked and so is the knight on d4. What must Black play?
} e4 $3 {You put the third one under attack as well! How many pieces can White
take in one move!} 11. cxd4 (11. fxg4 Bd6 {already gives Black excellent play.}
) 11... Bd6 {It's not about how many pieces you have on the board. It's all
about how many pieces are actively taking part in the game.} 12. Bxb5+ (12. Qe2
$5 O-O (12... Bxg3+ 13. hxg3 Qxh1 14. Qxb5+ (14. Qxe4+ Be6 $17) 14... Bd7 15.
Qxd5 $18) 13. fxg4 Bxg3+ (13... Nb4 14. Qxb5 Nc2+ 15. Kd1 Nxa1 16. Nxe4 $18)
14. Kd1 $5 {The computer thinks that this position is winning for White. I
have my doubts. You can try to analyze this deeper. Remember, you can start a
chess engine in our Javascript player and try alternate lines.}) 12... Kd8 13.
O-O exf3 14. Rxf3 (14. gxf3 Bxg3 $19) 14... Rb8 $1 {The way Berliner gets all
his pieces into the game is quite inspiring. It doesn't matter if you are a
piece down, as long as the number of forces playing in the game is to your
favour.} 15. Be2 $2 (15. Bf1 Bxf3 16. Qxf3 Qxd4+ 17. Kh1 $16) 15... Bxf3 16.
Bxf3 Qxd4+ 17. Kh1 Bxg3 18. hxg3 {Black is better now because he brings in the
rook into the attack.} Rb6 $1 {A strong move threatening Rh6#} 19. d3 Ne3 20.
Bxe3 Qxe3 {Once again Rh6 is a big threat and there is only one way to stop it.
} 21. Bg4 h5 22. Bh3 g5 23. Nd2 (23. Bf5 h4 24. g4 h3 $19) 23... g4 24. Nc4
Qxg3 25. Nxb6 gxh3 26. Qf3 hxg2+ 27. Qxg2 Qxg2+ 28. Kxg2 {After all the
complications, material sanity has been restored. However, it is Black who now
has an extra pawn. How would you recapture the knight on b6?} cxb6 $1 {
Capturing away from the center, but now White has no way to create a passer on
the queenside.} (28... axb6 {looks logical, but in endgames it is better to
not allow the opponent to get an outside passed pawn, which White can do with
a4, b4 and a5.} 29. a4 Kd7 30. b4 Kc6 31. Rh1 $17) 29. Rf1 (29. Kh3 $5 $17)
29... Ke7 30. Re1+ Kd6 31. Rf1 Rc8 $1 {I like this decision very much. You
give up a pawn and get all your pieces co-ordinated.} 32. Rxf7 Rc7 33. Rf2 Ke5
{The h5 pawn ensures that all pawn endings are winning. Now Black uses his
king to inflict the damage.} 34. a4 Kd4 35. a5 Kxd3 36. Rf3+ Kc2 37. b4 b5 38.
a6 Rc4 39. Rf7 Rxb4 40. Rb7 Rg4+ 41. Kf3 b4 42. Rxa7 b3 {A great game by Hans
Berliner. The way he brought all his pieces into the attack is something to
learn from.} 0-1
