Q+R endgame for analysis Position for analysis:
White: Kg1, Qe5, Rb1, b4, c5, e3, g2, g5
Black (your sinful): Kg8, Qf7, Rf8, c6, d5, e4, g7, h7
---
The game went as
31. b5!? cxb5
---
And then my opponent allowed a blunder 32. Rxb5? and lost a Rook after 32. ... Qf1+
---
Instead of that, I see the white's sharp move
32. c6!?
---
I believe, Black has an edge, but ... is it enough to win?
Any ideas?
---
When I'll have more time, I'll give beginning of this game with short annotation.

Could somebody evaluate these lines? No many went into that position... (at least, public)...
So I'm continuing by providing one of possible lines:
--
31. b5!? сxb5 32. c6 Re8 33. Qd6 Qe6
and now:
a) 34. Qxe6 Bxe6 35. c7 Rc6 36. Rxb5 Rxc7 37. Rxd5
b) 34. Qc5 Rc8 35. Rxb5 Rxc6 36. Qxd5 Qxd5 37. Rxd5
--
Both of them looks like better for Black, or aren't they? :-)
Could somebody be able to found an inaccuracies in them? :-)

Auxiliary analysis I got the following private msg with analysis of (if the sender will allow his identity will be revealed).
It introduces into another line starting from 32. ... Qf2 ( to mine 32. Re8).

----------------------------------------
As to your message on GK regarding Q + R v Q + R:
31) b5! cxb5 32) c6! Qf2 33) Kh1 Qh4, threatening a repetitive check.
34) Qh2 Qxg5. The White rook cannot capture b5, due the mate from Rf1+, Qg1 Qh4#
35) c7 (Rc1 is countered by Qxe3, exd5 Rf1+ and mate follows. 35). . . Qxe3 36)Qe5 (not Qd6, since Qh6+ trades queens) Qh3+ 37)Kg1 Qc6 (guarding e6) 38)Rxb5 Qxb5?! 39)Qe6 Kh8 40)c8=Q Qb4!!

Just a different view on the problem.

Hello, loreta!
Yes, you may reveal my identity. I have been having difficulty posting messages on GK message board. The webmaster has not answered my queiry regarding this.
You may wish to contact him, so I can post messages, and discuss your excellent endgame positions directly on GK message board.

IMO I find it very difficult to believe that Black has an edge because White has dangerous threats on the queenside, which are not easily countered. However, from the position in question, Black has an easy draw with 32... Qf2+ 33. Kh1 Qh4+ 34. Qh2 Qxh2+ 35. Kxh2 Rc8. Black can try for more with 34... Qxg5, but White could just allow the perpetual check on move 34.

After 31. b5 cxb5 32. c6 Qf2+ 33. Kh1 Qh4+ 34. Qh2 Qxg5 35. c7 Qxe3 36. Qd6 Qh6+ 37. Qxh6 gxh6 an important position arises that every player should be aware of, where White wins easily after 38. Rxb5 because Black cannot prevent Rb8 and the two connected passers are not advanced enough to draw against the Rook. For example, 38... Rf1+ 39. Kh2 Rc1 40. Rb8+ Kf7 41. c8=Q Rxc8 42. Rxc8 d4 43. Rc4, or 42... Ke6 43. Kg3, etc.

I understand, a position isn't easy! Tnx friends, for your opinions,
But look at that Rokk's ending:
31. b5 cxb5 32. c6 Qf2+ 33. Kh1 Qh4+ 34. Qh2 Qxh2+ 35. Kxh2 Rc8
Doesn't Black have an edge in it?
As example, 35. Rxb5 Rxc6
And from there two lines start:
a) 36. Rxd5 Rc3
b) 36. Kg3
atrifix 24 ( +1 | -1 )
After 35... Rc8 we have arrived at a book draw, e.g. 36. Rxd5 Rc3 37. Rd4 Rxe3 38. Kg1 and Black cannot protect the pawn on e4. Even if you take away white's pawn on g5 and simply give White a pawn deficit the position is still a book draw.

Try again: So, it seems, a line with 32. ... Qf2+ leads to a draw...
So we have to go back to initially proposed line?
31. b5!? сxb5 32. c6 Re8 33. Qd6 Qe6
Isn't it even more complex?

{ I was seeking that position but just now noticed sadly that I can't gain much of it. Could someone to find an improvement for Black somewhere starting from move 18?}
