Patzer Variation or Refutation?

By Michael Goeller

I tend to think of the Urusov Gambit as a way of reaching the Two Knights Defense after 1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Nc6! since this is the most common approach for Black. Most other lines favor White and are probably reckless to enter as Black against a well-prepared opponent. But there is one move that continues to trouble me and which I have come to see as probably the most important to Urusov Gambit theory: 4...Bb4+!

My friend Max Burkett likes to call this the Patzer Variation (after the phrase "patzer sees a check, patzer plays a check"). But it may actually come the closest to being a "refutation" of the Urusov, in that it probably allows Black to equalize with the most precise play. Fortunately, the move continues to be favored by patzers, so you will not tend to see Black playing precisely after giving check. But when Black knows what he is doing, it can be a real struggle for White to find an advantage.

The following two recent games explore what I have come to regard as the main line of the Patzer: 1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Bb4+ 5.c3 dxc3 6.bxc3 Bc5 7.e5 d5 8.exf6 dxc4 9.Qe2+ Be6 10.fxg7 Rg8 11.Ng5 when both sides walk a fine line between equality and disadvantage. White's results in this line have been good, but it is a very close struggle with best play. Of course, there are alternatives for White and more speculative ways of playing earlier on (as I indicate), so the Urusov is alive and well. But anyone who plays it should be prepared for the occasional patzer who knows what he is doing....

1. e4 e5 2. Bc4 Nf6 3. d4 exd4 4. Nf3 Bb4+! 5. c3 dxc3










6. bxc3

For those who enjoy playing with Danish Dynamite, these alternatives are worth exploring:

a) 6. O-O!? cxb2 7. Bxb2 O-O 8. e5 Ne4!

 

b) 6. Nxc3!? O-O (6... Nxe4 7. O-O (7. Bxf7+ Kxf7 8. Qd5+ Kf8 9. Qxe4 Qe7 10. Qxe7+ Bxe7 11. Nd5 Na6) 7... Bxc3! (7... Nxc3?! 8. bxc3 Be7 9. Ng5 d5 10. Qxd5 Qxd5 11. Bxd5 O-O 12.

Ng5 Muller and Voigt) 10. Qc2 Nc6 11. Bf4 Nuenchert-Hobusch, Halle 1979) 8. Bd3 Bxc3+ 9. bxc3 Ne4 10. Qc2 Bf5 11. O-O Re8 12. Nd4 Bg6 13. f4 c5 14. f5 Bh5 15. Nf3 Nc6 16.

6... Bc5!

This is probably Black's best, though 6...d5!? is also important:

a) 6... Be7?! 7. e5 Ng4 8. h3 Nh6 9. Bxh6 gxh6 10. Qd5 Rf8 11. Qe4

 

b) 6... Ba5?! 7. Ba3! (7. e5 d5) 7... d6 8. e5! Ne4 (8... dxe5 9. Qb3) 9. Qa4+! c6 10. Bxf7+ Kxf7 11. Qxe4

 

c) 6... d5!? leads to an equally complex and interesting endgame after 7. cxb4! (White gets nothing from either 7. Qa4+!? Qd7! 8. Qxb4 dxc4 9. Qxc4 (9. Ba3?! b6!) 9... Qe6= or 7. exd5?! Be7!) 7... dxc4 8. Qxd8+ Kxd8 9. Bg5 (9. Nc3) 9... Ke8 (9... h6 10. Bxf6+ gxf6 11. Nc3 Rg8 12. O-O-O+) 10. Nc3 c6 11. Nd2

 

d) 6... Bf8? 7. e5 Ng8 8. O-O

7. e5










7. O-O d5! (7... Nxe4 8. Bxf7+ Kxf7 9. Qd5+ Kf8 10. Qxe4 d5 11. Qf4+) 8. exd5 O-O 9. Bg5=

 

7... d5

All other moves basically are bad:

a) 7... Ng4? 8. Bxf7+! Kxf7 9. Ng5+ (9. Qd5+) 9... Ke8 10. Qxg4

 

b) 7... Ne4? 8. Qd5! Bxf2+ 9. Kf1 O-O 10. Qxe4

 

c) 7... Qe7?! 8. O-O! Ne4 9. Bd5 Nxf2 10. Rxf2 Bxf2+ 11. Kxf2 O-O 12. Ba3 d6 13. exd6 cxd6 14. Bxd6 Qf6 15. Bxf8 Kxf8 16. Qd4 Qxd4+ 17. cxd4 Nd7 18. Nc3 Nf6 19. Bb3 Bf5 20. Ke3 Re8+ 21.

8. exf6

8. Bd3 Ne4?! (8... Ng4! 9. O-O Nc6 10. Qe2 Qe7 11. Bf4 f6) 9. Bxe4 dxe4 10. Qxd8+ Kxd8 11. Ng5 Be6 12. Nxe4 Be7 13. Be3 Nd7 14. f4 f6 15. exf6 Nxf6 16. Ng5 Bd5= 1-0 Souevamanien,P-Rudiano,N/Maisons Alfort 2001 (45).

 

8... dxc4










9. Qe2+

White obviously has a wide choice here, but only 9.Qxd8+ promises much-- though it is not very different from the main line:

a) 9. Qa4+?! Nc6 10. Qxc4 Bf8 11. Qe2+ Be6 12. fxg7 Bxg7

 

b) 9. fxg7?! Qxd1+ 10. Kxd1 Rg8 11. Bh6 f6! 12. Re1+ Kf7

9... Be6 10. fxg7 Rg8 11. Ng5

The chief developing moves in this position do not seem as promising:

a) 11. Bg5?! Qd5?! (11... Qd3!) 12. O-O Nd7 13. Rd1 Qf5 14. Nbd2 Rxg7 15. Ne4 Be7 16. Nh4 Qg4 17. f3 Qh5 18. Bxe7 Kxe7 19. Rxd7+ Kf8 20. Rxc7 Qxh4 21. Qd2 Rd8 22. Qe3 Rg6 23. Qc5+ Kg8 24.

b) 11. O-O!? This move will appeal to Urusov players looking for a tactical battle, but I think Black has a lot of good ideas himself. 11... Nc6? Black has three alternatives which seem to grant at least equal chances:

(a) 11... Qf6! 12. Ng5 Rxg7! 13. Nxe6 Qxe6

13. Bh6!? Be7 14. Qxe6 fxe6 is a nuance you will see in the next game, but it seems to encourage Black to play the good move ...Be7.

 

13... fxe6 14. Bh6










This is probably the critical position for the Urusov Gambit. I am very curious to see how this line works out, but I think White probably only has equality after Black manages the exchange of his doubled c-pawn for White's passed g-pawn on the 7th rank. There may still be play in the resulting endgame due to Black's potentially weak e-pawn, but that is not the sort of advantage you can convert.

This looks like a nice square for the Knight, but it probably helps White to move his King.
