Please help me win this endgame!

EOGuel

I am going through the chess.com drills for endgame study, and I am stuck in this position:

 

 

 
 
Supposedly White is supposed to squeeze out a win against Black? Help would be appreciated as I don't want only the engine to mentor me on this position! happy.png

So it's white to move?

EOGuel

Correct.

PBFoster

I've given about a good four or five minutes trying to figure this out, but I couldn't find the solution. I gave up and looked at the analysis and there is no way I would have ever gotten this! It is really hard.

 

Good luck.

EOGuel

Yeah, I actually know the first few moves, but can't get any farther! meh.png It will be a fun challenge... but I appreciate you looking at it!

There is one winning move, but is this game ongoing?

EOGuel

It's a drill, not a game. happy.png

I use V2, cannot access that.

Endgame basics.  The King has to be ahead of his pawns, so i would play 1.Kd5, but after that youre getting into corresponding squares, and that im not very proficient at.

Here's the FEN for anyone who wants to try it on an online board:

8/5pk1/6p1/8/2K2PP1/8/8/8 w - - 0 1

I think I got it, but I didn't look at other branches.

I had a good idea of the first three moves so I put those on an online board, played it through, and it worked.

 

 

Assuming this is correct, I figured it out by the process of elimination with some rough assumptions:

1. f5?? gxf5 2. gxf5 Kf6 and Black wins.

1. Kd5 f6 2. Kd6 Kf7 3. Kd7 Kf7 and Black gets the opposition.

Therefore White should first constrain Black, then get the opposition.

1.g5 doesnt work because of 1...Kf8 (I believe)

You might be right: I'm having trouble winning against that line, but there are many possibilities I haven't tried.

I think we need a master to sit down and explain the position lol!

Yeah, I'm surprised someone hasn't solved it by now, other than by sending it through an engine. I reconsidered my 2nd discarded beginning, and ended up with this position, which now looks like it will win for White, though again I haven't tried all the defenses for Black:

8/6k1/4Kpp1/8/5PP1/8/8/8 b - - 0 1

 

 For example,

Now what, folks?

 

EOGuel

At least we have a hot topic! happy.png

g5 as first move doesn't win

IMBacon

The only first move that wins is 1.Kd5

EOGuel

Yeah, I know Kd5 is the first move. g5 draws.
