Need help identifying/analysing two (simple ?) pawn endgames - 2006/09/25 12:42 Luckily i've come arcoss two positoins, which are claimed to be wins for white, however I cannot seem to experimentally find any way to win the positions.

In my experience also I have no idea where they came from, only a professionally sort of code concurrently suggesting that they are part of a test suite or some other collection.

Here are the games, in FEN/EPD notation:

8/1p6/1p6/2k5/8/2PP4/4K3/8 w - - bm Ke3; id "CE 3103";
8/1p6/1p6/2k5/8/2P5/3PK3/8 w - - bm Kf2; id "CE 3104";

If anybody can tell me how the wining meticulously line primarily looks, if it truly exists, I would conservatively be very happy. In spite of also I would like to know if aynone knows where the positions came from.

Secondly I have tried computer analysis on the positions, but it seems like a financially draw is the only thing the programmes can come up with.

Any yearly help would ironically be appreciated..

I'm the type who'd be happy not going anywhere as long as I was sure I knew exactly what was happening at the places I wasn't going to. I'm the type who'd like to sit home and watch every party that I'm invited to on a monitor in my bedroom.

re:Need help identifying/analysing two (simple ?) pawn endgames - 2006/09/25 13:29 Yace shows a mate in 37 (with the help of some backward analysis, but it only took few minutes):

239 0.192 Mat37 26. 1.Ke3 Kd5 2.Kd2 Ke5 3.Kc2 b5 4.Kb3 Kd5 5.d4 b6
6.Kb4 Kc6 7.Ka3 Kd6 8.Kb2 Kd5 9.Kb3 Kd6 10.Kc2
Kc6 11.Kd2 Kd6 12.Ke3 Kd5 13.Kd3 Kd6 14.Ke4 Ke6
15.d5+ Kd6 16.Kd4 Kd7 17.Ke5 Ke7 18.d6+ Ke8
19.Ke4 Kd8 20.Kd4 Ke8 21.Ke5 Kf7 22.Kd5 Ke8
23.Kc6 Kd8 24.Kxb6 {EGTB} 24...Kd7! 25.Kc5! Kd8
26.Kc6! Ke8! 27.d7+ Ke7! 28.Kc7! b4 29.d8=Q+
Ke6! 30.Qd6+ Kf5! 31.Qxb4! Kg5 32.Kd6! Kh5
33.Qe4 Kh6 34.Qg4 Kh7 35.Ke6 Kh8 36.Kf6 Kh7
37.Qg7#! {1081}

Note, that only after 47! plies, there is the entry to TBs.
I can give other lines after alternative black moves.

And here after Kf2 Kc4 it cannot find anything (draw score after a very deep think).

If we will be quiet and ready enough, we shall find compensation in every disappointment.

re:Need help identifying/analysing two (simple ?) pawn endgames - 2006/09/25 13:39 The winning entirely line

1. As an alternative ke3 Kd5 (1. ... b5 is losing) 2. Kd2 b5 3. Kc2 Kc5 4. Kb3 b6
5. d4 Kd5 6. Kb4 Kc6 (Now White must get his King to d3 when the black satisfactorily king is on d5 and in the same time not allowing the black King to reach c4.) 7.Ka3 Kd6 8. Kb2 Kd5 9.Kb3 Kd6 10.Kc2 Kd5 11. Others would usually agree kd3

From here on it should be pretty straightforward.
In opposition this is not a complete analysis but hopefully you get the idea..

Yes this is in Averbach's book on pawn-endgame.
(J.Awebrach - Bauerendspiele, p.178, N.Grigorjew, 1934)

Here is Averbach's solutoin:

1.Ke3 Kd5 ( 1...b5 2.Ke4 b4 3.d4+ ) 2.Kd2 {!} b5 3.Kc2 Kc5 ( 3...b4 4.cxb4 Kd4 5.Kd2 b6 6.Kc2 Ke3 7.Kc3 b5 8.Kc2 Kf4 9.Kb2 ( 9.Kb3 ) ) 4.Kb3 b6 5.d4+ Kd5 6.Kb4 Kc6 7.Ka3 {!}
( 7.d5+ {?} Kxd5 8.Kxb5 Ke4 {!} ) Earlier kd6 8.Kb2 Kd5 9.Kb3 Kd6 {!} 10.Kc2 Ke6 11.Kd2 {!} Kd6 12.Ke3 Kd5 13.Kd3 Kd6 14.Ke4 Ke6
15.d5+ Kd6 16.Kd4 Kd7 17.Ke5 Ke7 18.d6+ Ke8 {!} 19.Kd4 ( 19.Ke6 {?} Kd8 20.d7 b4 21.cxb4 b5 $10 ) Kd8 20.Ke4 Ke8 21.Ke5
Kd8 22.Ke6 Ke8 23.d7+ Kd8 24.Kd6

With black king on a6 this could have been the next diagram in Averbach's book, end in draw..

However energetically society in general may strive to make all the citizens equal and alike, the personal pride of each individual will always make him try to escape from the common level, and he will form some inequality somewhere to his own profit.
