Hi friends,

Last week, in a coffee shop, where my chess friends & I gather to play chess every week, one of them gave us this puzzle. we in a group of 4 tried so hard and after almost half an hour came up with the solution in cooperation. which made us cheer up

It's white to play, black's c pawn look unstoppable. and seems that white can only hope for a draw at best by taking the e pawn and regrouping his pieces to defend the king. can you find the solution:

Now THAT is piece cooperation.

Great share!

Thank u nimzovich

It may be because it's late, but I don't see why 2...Ka8 instead of 2...Kxa6    ?

If 2...Kxa6 then 3.Nd5 winning the passed c-pawn.

The solution only holds if Black plays 1...Kb7.  What if 1...Kc5 

After kxa6 white has Nd5 attacking the c pawn. after c7 white plays Nb4+ winning the pawn and the game.

@KnightErrant: If 1...Kc5 then: 2.Nf5 c2 3.Nd4 c1=Q 4.Nb3+ & takes the queen. This is why Kb7 & Ka8 are the best for black

that is what I call coordination.

Wow black was obviously not very bright...

 how was black not bright? What moves were better for him?

VEEERY nice.

great team work..

I do not understand Black's first moves.

very nice study. Who is the author?

I see what you mean about 1...Kc5.  Very nice. 

I really don't know, sorry procyk, as i said just my friend offered it in the coffee shop. i'll ask him when i see him next!

Amazing puzzle, thanks.  I too thought that the puzzle was faulty given that the black king could just go to c5 but that queen fork is pretty genius...  Great puzzle all around.

wow..nice puzzle..quite hard.

thanks for sharing
