A nice regroupment. It is time for Black to show some  strength and he should be better on the queenside. The backward c3-pawn is an obvious counter-attacking candidate.
1. e2e4  1... c7c6  2. d2d4  2... d7d5  3. e4e5 A solid choice in the final game. 3... c8f5  4. g1f3  4... e7e6  5. f1e2  5... g8e7  6. c2c3  6... h7h6  7. e1g1  7... b8d7  8. a2a4  8... a7a5  9. b1a3  9... f5h7  10. f3e1 A standard maneuver. The knight opens the  road for the f-pawn. 10... e7g6  11. e2d3 There were other moves that would have prepared the kingside  assault, like 11... f8e7  12. a3c2  12... e8g8 Murzin finished the development, but has a  problem with the lack of space. There are too many black pieces on board,  and they are obstructing each other. 13. g2g3 Restricting the mobility of  the knight. Iordachescu plans to ramp up the pressure against the enemy  position with his h-pawn. 13... c6c5  14. h2h4  14... c5c4 In return, Black removes the bishop from its  strongest diagonal. 15. d3e2  15... d7b8 This manuever, though, seems a bit slow.  16. e1g2  16... b8c6  17. h4h5  17... g6h8  18. c2e3  18... d8d7  19. f2f4 Finally this pawn makes a move. 19... f7f6  20. e5f6  20... e7f6  21. e2g4 Iordachescu continues with the obvious  and logical moves, and this allows his young opponent the precious time to bring his pieces back in the game. 21... h8f7  22. b2b3 This is still the best. White keeps some pressure,  however his young opponent defends very accurately. 22... c4b3  23. d1b3  23... c6e7  24. c1a3  24... h7e4  25. b3b5  25... d7c8 Correct! 26. a1c1
