  Ron: Some comments: 1. Ineresting mode of development by White against the Scandinavian.

2. Note White's sacrifice 26 Rxf6! and his subsequent play.

  Ron: <bright1: How does White win if Black plays 43. ... Rc8 ?>

Indeed, I do not see how White can win after that move.

Oct-06-07  hovik2003: How about
43...Rc8 44.Bd6 Rxc6 45.Qe7+ Kg8 (If Kh8 46.Be5+ Kg8 47.Qg7mate) 46.Be5 and black have to give up his rook to prevent mate on g7.

and if black doesn't take the c pawn by 44...Rxc6, on any black move white plays 45.c7 with total domination of black squars and potential extra queen.

  Ron: Thanks for the reply <hovik2002> but the thing is this: after 43. ... Rc8 44. Bd6 Re8!; if White then plays 45. c7 then White will be in hot water: 45. ... Re2 threatening mate, which White can avoid but then Black would have the advantageous position. After 44. ... Re8 it seems that White would have nothing better than to repeat position. This seems to be a premature resignation by Black.

Oct-06-07  Gilmoy: 43.c6 was to let the Bishop out!

43..Rc8

[A] 44.Bf8 Rc7 (Qg8 45.Qe7+) (Rxf8 loses the a-pawn) 45.Qf4 Qxc6 (Rxc6 => 47.Qg7#) 46.Qxh6+ Kg8 47.Ba3 and Black would like to simultaneously defend g6, g7, f8, and b2.

[B] 44.Ba3

[B1] 44..Rxc6 45.Qe7+ Kg8 46.Qf8+ Kh7 47.Bb2 (mate fork g7/h8) Qg8 48.Qe7+ and 49.#

[B2] 44..Qxc6 45.Qf7+ Kh8 46.Bb2+ 1-0

[B3] 44..Rc7 45.Bb2 g5 (so that Qh8 isn't #) 46.Be5 Qxc6 47.Qf5+ (defends a5 and c2) Kg8 47.Bxc7 Qxc7+ 48.g3 Black has weak a- and h-pawns, a weak 6th rank, and its K is exposed. White has a clear plan of a6-Qb7, and Black's K is trapped outside the box.

Oct-07-07  hovik2003: hovik2003: <Gilmoy> Interesting analyzes but still I think 43...Rc8 44.Bd6! is winning move. for [B1] 44.Ba3 Rxc6 45.Qe7+ Kg8 46.Qf8+ kh7 47.Bb2 Black simply exchange queens by 47...Qd6+ and wins. White have to guard e file evenso 46.Qe8+ Kh7 47.Bb2 g5! draws for [B2] 44.Ba3 Qxc6?? is obviously bad, Black have to guard f7 for [B3] 44.Ba3 Rc7? 48.Bb2 g5 we get an echo-variation of [B1] with c6 pawn intact so Rxc6! is the move not Rc7?

<Ron>
there have to be a winning move after 43...Rc8 44.Bd6 Re8! 45.c7 Re2 white draws easily by 46.Qh1+! Kxh1 47.c8Q+ but I don't see how he wins. I am gonna ask Petrosian himself about this when he gets back from Antalya.

One more thing maybe black lost on time after checking the scoresheets by arbitor.

Dec-26-07  Treadhead57: <hovik2003> <I am gonna ask Petrosian himself about this when he gets back from Antalya.>

What did he say about this? I'm curious.

I was in Armenia in Oct. and Nov. but I was being so busy in countryside I only was in Yerevan once or twice and I couldn't go to Chess Federation House where you meet most of Armenian GMs there. But I promise I will follow this when I get back to Armenia in February.
