Why no engines find that 22....Rc7 looses  to 23.g6!! completely

r5k1/1qrnbppp/3p4/3Pp1PP/pp2N1R1/3QBP2/PPP5/1K1R4 w - - 0 23
Parent - - By Permanent Brain (*****) Date 2011-02-06 07:52
Do you have a convincing variation after 23.g6? I was not able to verify with engine analysis that Black must lose after it.
Parent - - By Master Om (Bronze) [in] Date 2011-02-06 08:23
Yes. There is Slaughtering of black in all variations.

My guess is: If computers do not find a wind here, there is none! This is a typical position where computers are very strong.

Just a quick manual analysis assisted by Rybka:

23. g6 fxg6 24. hxg6 h6 25. Bxh6 gxh6 26. Qe3 b3 27. cxb3 axb3 28. a3 Bf6 29.
g7
Parent - - By Master Om (Bronze) [in] Date 2011-02-06 16:53

>23. g6 fxg6 24. hxg6 h6 25. Bxh6 gxh6 26. Qe3 b3 27. cxb3 axb3 28. a3 Bf6 29.g7


23. g6!! fxg6 24. hxg6 h6?? 25. Bxh6!! gxh6?? 26. Qe3 b3 27. cxb3 axb3 28. a3 Bf6 29.g7
Parent - - By Felix Kling (Gold) [de] Date 2011-02-06 17:04
24. ... h6 and 25 ... gxh6 don't deserve two question marks, everything else is losing, too. Although 24. ... h5 may be a better try (but loses to Nxd6).
Parent - - By Master Om (Bronze) [in] Date 2011-02-06 17:17
h5 is the best worse move  than h6 . So it deserves question mark. but looses to Ng3!! and not Nxd6
Parent - - By Felix Kling (Gold) [de] Date 2011-02-06 17:33 Edited 2011-02-06 17:36
ok, Ng3 is better than Nxd6. But in any case, you can't give a ?? to a move that may deserve only a ?!. And you shouldn't give a ?? to a move that has no better alternatives :)

or do you give your moves always a !! and your opponent's moves a ?? :) Btw., I found g6 and Bxh6 with Rybka in less than a minute. You should give it a ! only. Be modest :)
Parent - - By Master Om (Bronze) [in] Date 2011-02-06 17:45
Did you run Rybka 4 unattended ?  Its impossible for Rybka to find unattended and that too in a minute. I ran it for 2 hours in mpv 5 and best move was f4.
Parent - By Felix Kling (Gold) [de] Date 2011-02-06 18:48
sorry, it's a misunderstanding. What I mean is that the move is not "that" brilliant, since a human analysing with an engine finds it rather quickly.
Parent - - By SchachProfi (****) [de] Date 2011-02-06 17:53
Of course you find it in a minute when its already in the hash :roll:
Parent - By Felix Kling (Gold) [de] Date 2011-02-06 18:47
that's not what I wanted to say, what I mean is that it's not hard to spot with engine help. I don't want to say Rybka finds it that quickly.

Yes. After running Idea overnight the best move was Rc7 and i was expecting Ng3 then Rc6!!. I saw g6!! but found that after fg6 hg6 h6 I can play b3 :cry::cry::cry: missing that Bh6 not coming. I and my "IDeA" missed. :confused::confused::confused:

Parent - - By Felix Kling (Gold) [de] Date 2011-02-06 16:51
it looks like a tricky pruning example, there is a good, maybe also winning in the long term, move (f4) and many alternatives, so g6 simply doesn't get enough time, especially since Bxh6 isn't that easy to find either.
Parent - - By Master Om (Bronze) [in] Date 2011-02-06 17:02
Its tricky . None engines find it and not even in mpv in 5 pv lines. The only engine that considers that is Zappa Mexico II on special settings and Rybka 3 human 3 with the former finding Bxh6 in its mpv.

I can understand you wanting to bring this position up. As it is a special position, it would have better to do it after the game was over.

Why do you need to wait 5 hours? If you know you are beat then why not resign? If I can't get a good answer to this. Than I can move this to the mods arena and when I know the game is over I will bring it back.

Conclusion:
So, you now see answer to your question.
Research nodes dramatically expand, depends of good mainlines from both sides in each move.
Engine/(s) found solution in long time (not on correspondence chess game),
because suggested mainlines is semiforced until "heavyweight" pieces endgame.
B90 is very deep (for example: second sacrifice after Bxh6, blacks sacrifice back),
helps only home analysis of opening book, not IDeA.

Joke:
I am confident that with this "stone" your opponent have already walked in pocket.
You simple hit towards him ....

My (human) point of view about position:

Both sides contrattacking kings by a1-h8 diagonale.
White control a1-h8-h1-a1 triangle, black - a1-h8-a8-a1.
White "heavyweight" pieces is closer on center d4-d5-e5-e4 and
have more functions than black "heavyweight" pieces.
They are better protect their king and the attacking opponent king.
Primary attacking pieces by white - pawns g5/h5.
Primary attacking pieces by black - pawns a4/b4.
Very similar.
Except of one ......
This element is too very important in contract bridge game.
FIRST TEMPO (move in chess, bidding/lead in bridge).
It allows you to control the situation with the same material resources.

Your analyze result look's correct.

Now we get winning string:
g5-g6 f7xg6 h5xg6 h7-h5 Ne4-g3 b4-b3 c2xb3 a4xb3 a2-a3 Nd7-f6 Rg4-b4 Qb7-c8 Ng3-f5 Rc7-b7 Rb4xb7 Qc8xb7 Be3-g5 Ra8-d8 Rd1-c1 Kg8-f8 Rc1-c6 Qb7-d7

My 23/81 is wider as your's 23/65, sorry.:razz:
