5... Be7 6. e3 Ne4
good move , 6...Ne4! threats wining a piece , and activing the knight to active position when just earlier it was pinned .

 
7. Bxe7 Qxe7 8. Nxe4 Bxe4 9. Nd2 Bb7 10. Be2
good move , idial position for the white LSB , another idea of this move is prepering 0-0 and Bf3 exchange the strong blacks LSB on b7 .

10... Qg5
capturing immideatly on g2 is not a good idea because of 10...Bxg2?!.11.Rg1!-Bb7.12.Rxg7 and white have good game .

11. Bf3 Bxf3 12. Qxf3 Nc6 13. Qg3 Qxg3 14. hxg3 Ke7
when the are no Queens on the board , there is no threat of dangerous attacks on the black king , therefor Capablanca choose to enter the rooks to the game and activing the king as prepering to an better endgame .

 
15. g4 h6 16. a3 a6 17. Ke2 Rhb8
good move , the idea is to advanced b5 and open B file for the black rooks , if 17... b5?! was sooner played so 18.d5-exd5.19.cxd5-Ne5.20.f3 and probably drawn game .

 
18. Ne4 b5 19. c5 d5
good move , black wishes to break whites chain of pawns on the center , the idea is , after the knight retreats to g3 or d2 , or c3 , black will play e5!.

20. cxd6 e.p.+ cxd6 21. f4 Rbc8 22. f5
maybe?, it was better to play .22. Rac1-Na5.23.Nc3-Nc4 and blacks chances are in favor to win .

 
22... Na5 23. Kd3 Nc4 24. Rab1
whites rook on b1 is in very unpleasente position however , even after 24.b3-Na5 , whites position wasnt get better at all.

 
24... d5 25. Nc3
not 25.Nc5?-Ne5+.26.dxe5-Rxc5 and black with big advantage.

 
25... Rc6 26. fxe6 fxe6 27. g5
white wishes to get reed from its double pawns on G file and, makes black Double pawns instead. however this free pawn is going to be very usefull for black .(see in blacks 31move).

the strong position of the black knight on c4 avoiding any active game frome the other rook getting active game because of the weak pawns on the whites queenside . therefore , black's totaly dominates the game and with the free pawn advantage makes first signs to ''the begining of the end'' for white .

29... Rac8 30. Na2 a5
good move , black large his space advantage on the queenside and even more cuts off the white pieces from the game .

 
31. Rf3+ Kg6 32. g4 Nd6
the black knight done his job on the queen side , and after the damage has been done to white , black prepares kind of a choke ring around the whits king neck .
