Well, I have spent some time analysing the game proper and have found some improvement, I think. Here's the analysis.

I think Black should have tried 17... Qxa2!? with the possible lines:
18. c4 Bxe4 19. fxg7 Bxg7 20. Qxe4 h6 21. cxb5 (21.Ne5!? Bxe5 22. Qxe5 O-O 23. Rb2 Qa3 24. Rf3 Qa1+ 25. Bf1 Rfd8 26. Rg3+ Kf8 27.
Qg7+ Ke7 28. Rf3 Rf8 29. cxb5 axb5 30. Rf6 Rd1 31. Rbf2 Qd4+=) 21... O-O 22. Bd3 f5!? (22... Rxd3?! 23. Qxd3 axb5 24. Qxb5 Qa7+ 25. Kh1 Nd7 26. Qc6 Nc5 27. Rfd1 Qa3+/=) 23. Qc4 Qxc4 24. Bxc4 Rd6 25. Rfd1 Rxd1+ 26. Rxd1 axb5 27.Bxe6+ Kh7 28. Rd5 b4 29. Bxf5+ Kg8 30. Rb5 Na6 31. Bd3 Rc8 32. Be4 Bf8= 

I didn't find any decisive advantage for White, but, on the other hand, Black has to defend thoroughly all the way. May be, that is why it's not so much playable on the pro-level. Who would like to make 20 good moves just to save the game after hard defence?! So the Poisonous Pawn Variation must be much safer to play instead.

Right, the words should be coupled with weighty arguments, aren't they? All right, the variations will come on Monday. I'm off for my weekend now. Well, have nice weekend too!

12...Ra7! (put to practice by Lev Polugaevsky) is much better.

Ok - for this move I recommend looking at Negi-Hermannson (18...g6 is bad and should be replaced by 18...Qc7 - but after 19.a4 Black still has too much problems) and Leko-Ghaem (if 19...b4 in Negi game after 18...Qc7 19.a4 it transposes). If Black doesnt take on b2, but plays Qc7 immediately I see not so much difference, all White's ideas (pawnbreaks on the queenside and various sacs against the Black king) seem to work.

Perhaps you can rescue the Polu? I would hope so, cause it is a fascinating variation and I tried it myself various times (rapid, blitz) - but at the moment I just have the feeling the whole variation is dead  Sad

The key move is 13.Kh1

Evidently, the text move 12...Qe5? may be poor. The idea 13 Kh1! was first played in Efimenko,Z-Miroshnichenko/Alushta 2002 1-0 
12...Ra7! (put to practice by Lev Polugaevsky) is much better. See Erenburg's comment to Mamedov,R-Mazi,L/EU ch Warsaw, 2005

Take a look at Ginsburg-Bromberger 2006, 1-0

perhaps you rethink your evaluation of the Polu then  Smiley

Why, no! Lol! The text proper has a very bad error (14...Qf6?). It has been long maintained that Qxf6 is too bad for that kind of warfare. In fact, in this variation the Black is (temporarily) behind in development, so it's high time to overtake arrears one way or the other. Thus, Ra7 (Polugaevsky's patent: look up his 'Birth of Variation') works towards it best.

I am not satisfied with the way how Palliser interprets  the Polugaevsky in his Naidorf book here on site. He has just given some ten lines to it and rates the variation in White's favour. However, even in the 8.e5! line (to be the most dangerous for Black) the Black is okay after 8...dxe5 9 fxe5 Qc7 10 exf6 Qe5+ 11 Be2 Qxg5 12 0-0 Ra7 13 Qd3 Rd7 14 Ne4! Qe5 15 Nf3! and here both 15... Qc7! and 15...Qxb2!? are all right for Black. See the games Pegorado, Nicola-Gouliev, Namig/2005 0-1 and Luther,Thomas-Bromberger, Stefan/2006 1/2 Strangely enough, those games are unavailable here on site. I've a vague suspision that Richard hasn't had much experience in the Polugaevsky and rates it rather low. Still, it's high playable as Black, to my mind.
