Besides Bragesjö's suggestion 18.-Rd7 Black has three other tries that are worth looking at:

**1.) 18.-Rfe8 19. Bd3 c5 20. Qa4 Rb8 21. b3 Red8 22. Qa6 Qc7 23. Rxe6 fxe6 24. Qxe6+ Kg7 25. h4 Re8 26. Qc4 Qe5 27. Kb1 (Becerra - Gallego, Linares 1997)**, and now Black could have got an equal game by

**27.-Rb4****2.) 18...Qd4 19. Bd3 c5 20. Re4 Qf2 21. Re2 Qd4 22. Qc3 Qxc3 23. bxc3 c4 24. Be4 Rd6 25. Rd1 Ra6 26. Kb1 Rb8+ 27. Ka1 Rb5 28. Rb1 Rba5 29. Rb2**

1/2-1/2 Broniek,M (2269)-Evans,G (2343)/Lechenicher SchachServer 2009 **3.) 18...Rd4 19. h4 h5** (this could be an improvement over Fedorowicz's 19.-Rd5)

**20. g4 Rfd8! 21. Be2** (21. gxh5 Qc7 22. Qe3 Qa5 23. a3 Qd5 with compensation)

**21... R4d5 22. Bc4 Ra5 23. Qc3 Bxc4 24. Qxc4 Rd4 25. Qc3** (25. Re8+ Kg7 26. Qc3 Qb4 27. Qxb4 Rxb4 28. a3 hxg4 =)

**25... Rxa2 26. b3 Qb4 27. Qxb4 **
