The Process of Decision Making in Chess Volume 2: Practice positions and solutions. Position 8.9

Solve for black:

Diagram 8.9- in this position black is the only one who can ever create a passed pawn by advancing his queenside pawn chain, even though material is equal. (White’s kingside pawn majority can never create a passed pawn due to this specific doubled-pawn structure -- in the given configuration, 4 vs. 3 is not enough.)
Challenge: what is the move order black should choose for advancing his queenside pawns in order to secure a sustainable passed pawn?

Would it be d3.

Roger

I apologize if I do not know the rules of the game.  d3 would not work they could exchange and our pawn would be overextended

D3 seems fine, except for his king will be able to get over in time and you have a locked position that some one will zugzwang.  I would start with a5.

Kd3, f4, a5?

the king can reach the pawn so after d3 cxd and cxd the black king can reach the passed pawn in time.

I would start with bringing my King into play with Kd6, Kc5, then I would advance my a pawn followed by my b pawn, c pawn and finally my d pawn

I take back the c pawn move it may not be needed to advance right away.

Is this obligatory to bring the black king? does white have time to bring his king over as well? is there a solution that doesn't allow white enough time to bring his king to the queenside?

a5

? that's it? and white immediately resigns? what is the plan, including the most challangeing resistance for white?

The King is going to need to get in play as just one past pawn can be stopped by the opposing King. So our King is going to have to get in play eventually. Might as will be now, as we have a space advantage with our King and whites King is kind of cramped.

 I would bring the king up near the d pawn so that the king could not get it. Then, if the king tried to threaten the d pawn, then I will use another pawn to try to get to the end while the king is still near the d column. 

I know it starts with a4 but im not sure of the continuation after that

er a5 i mean

1...a5 2.Kf1 b4 3.a4 c3. ( b3?)  4.bxc3 d3 5.Ke1 dxc2 6.Kd2 b3 7.Kc1 Ke6 8.f4 Kd5 9.f3 Kc4 10.Kd2 f5 

This is the line from another member. I put instead of bxc3 to b3.. I don't have a search engine to help run

through the list. Can anyone run that variation?

I would go 1...d3 if 2.cxd3 cxd3 black gets his king to d4, white gets his king to d2, black king c4 then b3, gives up his d file pawn but gains white's 2 pawns and will have 2 passed pawns on the a b files. or if 2.c3 Kd6 3.Kf1 Kc5 4.Ke1 a5 5.Kd2 b4 6.cxb4 axb4 7. axb4 Kxb4 8.Kc1 Kb3 9. h4 d2 check 10.Kxd2 Kxb2 and the c file pawn is free to queen or if 6.h4 bxa3 Kb5 and will eventually win whites a file pawn and will have both a & d file passed pawns

Please notice that the point of the exercises in our group is to understand ideas in chess based on identifying goals and finding solutions, definitely not using engines for calculations. Such depth of calculation is not required in any of the exercises, and in addition you will not learn from such a method of solving them. 

Pawn to a5 with b4 next. If white's a3 pawn moves to a4 then black's b5 pawn just moves forward. If black waits until black's b5 pawn moves to b4 and takes then the a5 pawn can recapture. The whole idea is that there will be 3 pawns to white's 2 and the pawn will queen.

There is no need to advance black's king because white's king can't get there quick enough to stop the advance.
