if the king is In front of the pawn,win,if not,draw.
Not quite (e.g. 1...Kg5 in @Zyryab's would draw). See my post #28 for a summary.
1...Kg5 was played in the game. That’s why I started with the position before this move.
As others have noted, there was no reason to sacrifice the knight, which could have captured both White pawns.

I wasn't criticising anything in your post (as you say OP blew it twice) - just using it to show @crycat's comment was inaccurate.

I know.
Your post #28 is excellent.

I just so happened to put out an article on King Pawn vs King endgames that features the square of the pawn, maintaining the opposition, and zugzwang.
If you don't know what one, two, or even all three of those are, I wrote it for you 
You can read it in a few minutes and it has diagrams and puzzles so you can practice without risking your rating.

I have two games that ended up with a draw, due to inaccurate calculation.
The 1st one was against 1800s rated player. It looks easy. But if your 1st move is incorrect, you will miss the win, like happened to me.
White to move
The 2nd one was against 1900s rated player. It is harder, because it still needs effort to execute accurate moves even after the correct 1st move. But if the 1st move is incorrect, you will miss the win, like happened to me.
White to move
I have posted these games in this forum. If you are interested in seeing the complete games, I will give the link after you try to solve the problems in these two games.
In the first, I would play Ke3 in a heartbeat. I know it wins. The second gives me pause, but I would play Ke5 on impulse. With enough time on the clock, I would want to calculate. Could end up in a race with both sides pushing passed pawns.
One of my games here on chess.com ALMOST ended with a very nice King-and-Pawn zugzwang.

Thanks for reply.
In the 1st case, why did you play Ke3 instead of Kd3 which has the shorter path to reach the left side ? But, unlike me who played Kd3, you played the correct move.
In the 2nd case, again you played the correct move, unlike me who rushed in to play Kg5, only to get stunned by black's response : g6 !
Therefore, I give the links for those games if you are interested to see the complete games :

What a vision to play 5. g5+ ! Yeah... zugzwang, I like the theme of zugzwang.

My instincts have been honed by much study and teaching of basic pawn endings. That's why. You must lengthen the distance Black's king must travel.
After Kd3 Kf3, both sides lose their pawns.
I looked at Kg5, saw g6 and it seems that Black's king centralizes as White's returns to where it came from. a single tempo can be the difference in such a pawn ending.

Thanks again for reply. Looking at your rating, there is no question about your knowledge and skill in endgame. I myself still need to know more.

Me too, my friend. Knights still give me difficulty, for example. And rook endings are difficult. I have an excellent grasp of most pawn endings, but still fail from time to time. But the quest to improve never ends.

In the actual game, my opponent played 46. ... g6 (losing quickly) instead of 46. ... Kf6.
The Zugzwang is what I had intended against the better Kf6 move.

The power of zz (zugzwang) becomes clear when you imagine both sides are allowed to "pass". Almost none of the earlier endgames wins if one side simply places his king on a critical access square and refuses to move it. Every "pass" constitutes a zz event and the repeated "pass" illustrates the true dependency on zz to win pawn endings. Not just once but in several phases of those endings.

You are right. Knights endgame, Rooks endgame, Rooks + Knights are difficult. Because these pieces have a lot of possibilities in their move that are hard to predict or determine.
I have several posts of my Rooks endgame, one ended up with a loss, one gave me a questionable win. If you are interested, I will share the link here.
Links are capital.
I will appreciate if you would kindly share your thoughts in those threads. Because it's quite likely I will encounter 2000s rated opponents again in next games, that I need to have solid knowledge and skill in this kind of Rooks endgame as well as Knights endgame.
In those games, I used my 2nd (alternate) account which has been approved by chess.com staff.
Thanks in advance.
