White to move. Can White win this or will Black hold?
i think black might manage to hold if he plays correctly. sorry i cant analyze it now, we have visitors.
if white plays anything other than c4 black will push the b pawn to clean up his own pawn structure.
so c4 is the necessary first move to save the small advantage white holds (the doubled black c pawn).
what will black reply?
… b5 doesn’t fix black’s pawns because White doesn’t have to take. In fact, taking would give black and outside passed pawn and potentially winning chances.
Also I don’t think 1. c4 even prevents 1… b5.
This is more about king position than anything else. I am still looking, but my intuition is either king up, or d4.
1. d4 prevents 1…c5, but I am just not sure than c5 needs to be prevented. But once it is prevented, and black’s c pawns fixed, then the white king can manuever forward and put black into zug when she needs to.
I’m just not convinced by 1. Ke5 c5 2. Kd5 c6+ 3. Kd6 b5 with the idea of 4…d4. So d4 first, and walk the king to c7.
1.ke5 is the winning move. u dont play 1…c5 2.kd5 u just continue to penetrate to the 8th rank eventually you will outflank black because you have c3 and any pawn moves by black weaken his structure. ill give some analysis if nobody else gets it
i think its pretty cool how nobody can get the ones that cannot be solved by a computer though 🙂
@jimmd – ^^ am i nobody? 🙂

PS: BTW – the principled solution of the somewhat similar endgame puzzle given a few blogs above can also be found herein… 🙂
yes exactly you found the main idea to get the superior king position and then push for d5..d6 and take on b6 this is the winning method.
