Black to play .
Here i am getting mixed results. Rybka says white wins , Shredder 12 says dead draw, Naum 4.2 Eval fluctuates  and i am in confusion . Any Ideas  how to analyse ?. My intuition says that its draw but rybka.....

> Any Ideas  how to analyse ?


Play shootouts, then analyze the resulting games, it should be more obvious then who was right.

Is that the only way to find out ?
Parent - - By Uly (Gold) [mx] Date 2010-04-03 12:07
No, it was just an idea.

Shoot out Does not yeild good results AFAIK. All engine will play as the think. That's the problem.
Parent - - By Uly (Gold) [mx] Date 2010-04-04 00:03
But if Rybka says it's winning, and Shredder says it's draw, and you let them play a game, what happens? If Rybka wins, you can try to find the critical variation and see if the game could have been savaged, similarly, if Shredder draws against Rybka then you can try the same idea and find if a win was lost somewhere, but in any case it'd be a signal that Shredder is probably right.

ya correct may be. But I myself found the plan. I have to sacrifice all my pawns for that single pawn and defend the position.

I cannot be sure, but I think that black can give up the bishop for the a-pawn when the blockade doesn't work and still be able to get a draw after playing ...f5, ...Ng3, and ...Kf4 (and ...Ne4 when necessary), and if white's king goes to far, start picking off pawns.  It should be a draw.

nice Idea!!!!

After Executing my plan i have this position.

I think this Draw. But None of the engines find it.
Parent - - By turbojuice1122 (Gold) [us] Date 2010-04-12 18:55
Oh, i was counting on you keeping those pawns.  My feeling is that this is now won for white.
Parent - - By Master Om (Bronze) [in] Date 2010-04-13 03:13
I have Got this position with a precise Analysis. This is draw AFAIK. i have not got a single variation that wins here for white becoz the king cant come out. At some point i threat to sac one piece for two pawns then K+R vs K+N or K+B is draw. You can check. Again interesting thing is none of the engines find it draw!! except a Oldie Zap!Chess Paderborn and in few lines by shredder. I heard that it is very strong in finding Draws.Rybka gives +/- 0.89 always but leads to repeatation of moves. Just see.

MCA (Rybka 3 1 cpu, broad tree, depth=7) ended  up with the following..

+884 =2410 -0 (63.4%)

So it's clearly a draw, unless black blunders..

FWIW, Rf8 was the most successful move (13.4%), followed by  Kh2 (12.3%), and  Rb8 / Rb8 (11.5% each).

> So it's clearly a draw, unless black blunders..


Or it's a win for white, unless white blunders, and it's very easy to blunder, causing more draws than wins.

The point is plan for black is easy to find now. Bishop remains in d1 h5 Diagonal and Knight in e4 . King moves from e3 to f4 and if Rf5 then Nd6 the again to e4 leading to perpetual moves. To get the feel for the position i made a 3 mins match. here are the games.

Nice work. I still marvel over how you correspondence players can save a position or push for a win.

>Nice work. I still marvel over how you correspondence players can save a position or push for a win.


I am still Learning. I think it has to do with Chess Knowledge a bit. In this correspondence games (Thanks to Vytron who pulled me into this where i am having fun) . In endgames no engine or computer analysis will help you but Dvoretsky endgame Manual  and Endgame basics by Rueben Fine still helps me. This game is still on and it will add new lines to chess theory. Here is the game.
