The Loewenthal Variation appears to be experiencing a bit of a revival, thanks mostly to its use by GM Vallejo Pons. All of the lines with a Black ...e5 in the Sicilian -- including the Sveshnikov, Loewenthal, and Haberditz -- are looking quite solid as Stefan Bücker suggests in a piece at ChessCafe titled "The Comeback of the ...e5 Sicilians."

White can also play simple chess with slightly better chances by 11. exd5 Nexd5 (11... 
Soltis)
12. Nxd5 Nxd5 13. Qa5 Be6! ( in an earlier game against the same opponent, Ledger had tried 13... Qc6?! 14. c4 Ne7 15. Qxe5 Qxg2 16. Be4 Qg4 17. Be3 f6 18. Qf4! Qxf4 19. Bxf4 Nc6 (despite the early complications, White still achieves the superiortwo-Bishops ending) 20. 
)

Black's plan appears to be to delay the exchange at d3 until he can gain a tempo when White plays a3 to clarify the position. White quickly achieved a much superior position in another Stephen C. Ledger game by closing off the kingside and attacking on the queenside after 15... Nxd3 16. cxd3 Be6 (16... a5 is suggested by Palliser and Emms as the way to prevent White's queenside play, but I'm not convinced)
17. f4 f6 (maybe here 17...f5!? is an even more significant improvement than the one I suggest below) 18. b4 Rd8 19. f5 Bd7 20. a4! Na7!? 21. Rfc1 Bc6 22. Rc5
16. f4 f6 17. a3 Nxd3 18. cxd3
The question has to be whether Black can do anything with the tempo he has gained from White playing 17.a3. This move ends up giving back that tempo as Black eventually decides upon the failed strategy of bringing his King over to the queenside. There has to be some way of improving here:
a) 18... Kd8?! 19. a4 a5?! 20. Rfc1 Kc7? 21. Bxa5
b) 18... f5! must be the right idea, preventing White from locking the Kingside where Black might be able to seek counterplay, e.g.: 19. fxe5
O-O! 20. Nd5 fxe4
19. b4! Kd6 20. a4 Kc7 21. a5 Rbd8 22. Rab1 Rhe8
Probably the best try, but Black is already worse. In another game that reached this same position, Black played 22... Kb8?! which left his King too exposed during the coming attack on the queenside: 23. b5 axb5 24. Rxb5 Ka7 25. Rfb1 Rhe8 26. f5 Bd7 27. Nc4 Bc8 28. Bc1 g6 29. fxg6 hxg6 30. Ba3 Re6 31. Bc5+ Ka8 32. a6 bxa6 33. Rb6 Rd7 34. Na5 Rc7 35. Nxc6 Bb7 36. Rxa6+ 1-0 Palac,M-Vokac,M/Montecatini Terme ITA 1997 (36).
24... f5!?
25. Rfb1 Rb8 26. f5! Ba2 27. R1b2 Bf7 28. Na4 Rec8 29. Nc5 Nd8
Within just a few moves, White has blocked off the kingside and positioned himself beautifully for the winning queenside attack. Black's forces, meanwhile, are completely tied down.
30. a6! b6 31. Na4 Be8 32. Rc2+ Nc6 33. Nxb6 Kd8
33... Rxb6 34. Ba5
beautifully demonstrates how effectively White has tied Black down.
34. Rd5+ Kc7 35. Nxc8 Kxc8 36. Ba5
(Threatening mate by Rd8.)
36... Rb1+ 37. Kf2 Kb8 38. Rdc5 Ra1 39. Bb4 Rxa6
40. Rb5+ Ka8 41. Bf8! Ra7 42. Rbc5 Kb7
Now all of Black's pawns fall like sitting ducks, but there was really no better option. If 42... Rf7 43. Bd6! and Black will end up down a piece no matter what he does, e.g.: 43... Na7 44. Rc8+ Nxc8 45. Rxc8+ Kb7 46. Rxe8
43. Bxg7 Ra3 44. Bxf6 Rxd3 45. Bxe5 Rb3 46. Rd2 d3 47. Rc3 Rb4 48. Bd6 Rxe4 49. Rcxd3 Na5 50. Re2 Rxe2+ 51. Kxe2 Bb5 52. f6 Bxd3+ 53. Kxd3 1-0
