Abrahamyan was probably expecting 5.f3, the Samisch Variation, which Foisor normally plays against the King's Indian Defense.

Foisor varies first from an Abrahamyan game played at the Olympiad in Germany last year. 13. Ndb5 Nf6 14. Bf3 g5 15. Bg3 g4 16. e5 Nh5 17. Bxg4 Nxg3 18. hxg3 Qxe5 19. Bxc8 Raxc8 20. Re1 Qg5 21.

13... g5 14. Bg3 Ne5 15. Bxa6 bxa6 16. Nd5

White will win her pawn back but she's not necessarily in a rush to do so.

16... Rb8 17. Nxc7 Qa4

Black threatens moves like ...c4 and ...Qxe4.

18. Qd6

18. Nd5!? Re8 (18... Qxe4? 19. Re1) (18... c4 19. Nd2) 19. Nxc5 Qxd1 20. Rfxd1 Rxb2 and white probably has a slight advantage thanks to black's pawn structure.

18... Rb6 19. Qxc5 Rc6

19... Nd3!? is an interesting way for black to regain the sacrificed pawn 20. Qe3 Nb4 21. Qe2 Nxa2 22. Nc5 Qd4 23. Rxa2 Qxc5

20. Qxa7 Nd3

Black has the initiative and a lot of activity for the two sacrificed pawns.

21. Nd5 Kh8 22. e5

Now might be a good time to bring the queen back into play 22. Qe3!? Nxb2 23. Rac1 Rxc1 24. Rxc1 Be6 (24... Qxa2? 25. Ra1) 25. h3 and black may be struggling to prove compensation for the pawn.

22... Nxe5 23. Nc3 Qb4 24. Rae1

24. f4! A hard move to find but a good one. Any knight move, allowing 25.fxg5, or black capturing the pawn herself allows the white rook on f1 to join in the action.

24... Nd3 25. Re4 Qb6 26. Qxb6

The commentary room mentioned 26. Qe7 trying to keep queens on but it doesn't seem any better than the move played after 26... Re6 27. Rxe6 Qxe6 and the queens will either get traded or black gets in ...f5 with a lot of play.

26... Rxb6 27. h4 Nxb2 28. Be5 Bb7 29. Bxg7+ Kxg7 30. Re2 Nd3 31. hxg5 hxg5 32. Rd2 Nf4 33. f3 Rh8 34. Ne2 Nxe2+ 35. Rxe2 Bd5 36. Re5 Bxb3 37. axb3

With everything swapped off peace reigns.
