{ A classic exampe of the weakness of a doubled pawn } 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. Nc3 Bb4 6. Nd5 Be7 7. d3 d6 8. Nb4 Bd7 9. Nxc6 Bxc6 10. Bxc6+ bxc6 11. O-O O-O 12. Qe2 c5 13. c3 { Intending Pd4. This will admittedly
afford his opponent a chance to rid himself a chance to rid himself of the
doubled pawn, but against this White will retain a formidable advantage in
freedom of movement. In addition to this method - preferred by Tarrasch -
White has the option of a different system which is really more appropriate to
the pawn formation, and which originated with Stenitiz. His scheme Nd2-c4-e3 :
suprisingly modern looking play } 13... Nd7 14. d4 exd4 15. cxd4 Bf6 { A good move, reanimating the Bishop } 16. Be3 ( 16. d5 Rb8 { Suddenly his pieces are working together like parts of a well-oiled machine } ) 16... cxd4 17. Bxd4 Re8 18. Qc2 { The Black doubled pawn has vanished, it is
true, but its after-effects will be felt for a very long time. As a result of
the method employed by White, the c-pawn will be a constant target } 18... Bxd4 $2 ( 18... c5 19. Bxf6 Qxf6 20. Nd2 Rab8 { the mobility of the Black
pieces would compensate to some extent for White's positional advantage } ) 19. Nxd4 Nc5 20. f3 Qf6 21. Rfd1 Reb8 22. Rab1 a5 { preventing Pb4 for the time being } 23. Kh1 { A tactical intermezzo } 23... Rb6 { The rook is vulnerable here } ( 23... -- 24. e5 Qxe5 25. Nc6 { Black doesn't have Qe3+ } ) ( 23... Rb7 ) 24. Ne2 Ne6 25. Nc3 Rc6 $2 ( 25... Qd8 26. Nd5 Rb7 { (Tarrasch and Steinitz) } ) 26. Qa4 Rc5 27. Nd5 Qd8 { Any other Queen move allows Pb4 } 28. Rbc1 Rxc1 29. Rxc1 c5 { From doubled pawn, via weak pawn, to backward pawn  A radical cure for the
weakness of the c-pawn, which however, only transfers the weakness to the
d-pawn.  This is a back ward pawn of the worst kind. It is the logical result
of White's plan of playing all the time against the weakness which began with
the doubled pawn. The weakness of a backard pawn consists in the fact that it
is fixed and cannot possibly be protected by another pawn. The result in the
present case is that White has full control of the central support pointd5 } 30. Rd1 Nd4 { This screening of the d-pawn is only temporary, since the
Knight can be driven back by Nc3-e2 } 31. Qc4 Rb8 32. b3 Rc8 $2 ( 32... Qd7 { counterplay with ... Pa4 } ) 33. Rxd4 $1 cxd4 34. Ne7+ ( 34. Qxc8 $2 Qxc8 35. Ne7+ Kf8 36. Nxc8 d3 $19 ) 34... Qxe7 35. Qxc8+ Qf8 36. Qxf8+ Kxf8 { Suddenly a second pawn has made its appearance in the Black game -
this time an isolated doubled pawn, of whose weakness there can be no doubt } 37. Kg1 Ke7 38. Kf2 d5 39. e5 ( 39. exd5 Kd6 40. Ke2 Kxd5 41. Kd3 { Create an out
side passed pawn to divert the King ... principle of two weaknesses } ) 39... Ke6 40. Ke2 $1 { Essential } ( 40. f4 g5 41. g3 gxf4 42. gxf4 Kf5 { White weakness } 43. Kf3 d3 $19 ) 40... Kxe5 41. Kd3 h5 42. a3 h4 43. b4 axb4 44. axb4 Kd6 45. Kxd4 Kc6 46. b5+ $2 ( 46. f4 $1 Kd6 ( 46... g6 47. b5+ Kxb5 48. Kxd5 $18 ) 47. b5 { two weaknesses } ) 46... Kxb5 47. Kxd5 Kb4 $1 48. Kd4 Kb5 49.
