I believe I invented this system, with which I had success in three or four county games while this system was in fashion. Now 4. c4 is the most common move. — BWRH
Caro-Kann, Exchange Variation
1. e4 c6 2. d4 d5 3. exd5 cxd5 4. Bd3 Nc6 5. c3 e6 6. Bf4 Bd6 7. Bxd6 Qxd6 8. Nf3 Nge7 9. O-O f6
The Hewson patent.
10. Re1 O-O 11. Qe2 Ng6 12. Bxg6 hxg6 13. Nh4? Kf7 14. Qg4?
Premature attack by White. Normally Black aims for ...e5 but now with the King's-side commitments a change of plan is both possible and desirable.
14...Ne7 15. Qg3 Qb6 16. b3 g5 17. Nf3 Rh8 18. h4?
Overlooking...
18...Nf5 19. Qg4 gxh4 20. Nbd2 Bd7 21. c4 Qd6 22. Nf1 g5
23. c5?!
Too passive, relieving tension.
23...Qf4! 24. N1h2?! [24. N3h2 is better. ] 24...Rag8 25. Rad1 Ke7 26. b4 a6 27. a3 Be8 28. Kf1 Bh5 29. Qxf4 gxf4 30. a4 Ng3+! 31. fxg3 hxg3 32. Ng4!
Keeps White in the game.
32...Bxg4 33. Rd3 Bxf3 34. Rxf3 Rh1+ 35. Ke2 Rxe1+ 36. Kxe1 e5 37. b5 axb5 38. axb5 Ra8 39. Rb3 e4 40. Rb2 f3 0-1
