Any guidelines for this endgame?

I played g5, Stockfish is saying Kf4 instead. Why? Here is the position and the game. If I should have done something else earlier in the game, feel free to comment on that as well. Thanks.

Aside from the fact that the white king can't move to f4, you can't ask Stockfish for endgame advice, even if you let it run all night.  The number of possibilities in a 12 piece endgame is too large for it to manage.

It looks like you did well.

Umm, I was black and the board is flipped to indicate this. Please look at it again. Also, I am posting here to ask a human for endgame advice, not Stockfish.

Aha! That makes all the difference.

Well, this certainly looks better for black than what happened.

It looks pretty straight forward.

Well in general terms it’s going to be a race and you clearly won’t be able to do without ...Kf4, so it makes sense to play that immediately rather than committing to a pawn move you may not need.

 

More specifically- given that you’re going to take on f3 and f2, it’s probably going to be the passed f-pawn that will run, rather than the g-pawn which is not going to be a passed pawn.

This is a king a pawn race. White needs 8 moves to promote, so Black has to be fast.

32...g5 wastes a move, as the fastest pawn of the three is the f- one, and an aditional bonus is that it promotes with check.

"given that you’re going to take on f3 and f2"


I just thought that white's f pawns would be bumping heads to get anywhere so a passed h pawn is what I was shooting for. I thought outside passed pawns were the way to go. The reason for g5 is what you see in the game. However, I didn't calculate that the black king could plow through the f pawns, get out of the way, and have time for the f pawn to promote before white could cause problems.

 

So, the decision (albeit wrong one), was to get the f pawns with my queen.

Certainly 25. ... or 26. ... taking with the pawn would have been better.

Promotion square of pawns

Promote with check

Remember to look for this possibility

Guidelines are all very fine, but any time you substitute vague guidelines for calculation, you are asking for trouble! And nowhere is this more true than in king and pawn endings. As pfren and others have pointed out, this is a race. You can't figure out a race using "guidelines." you have to count it out. Ask any strong player for help in this position, and the first thing he would say is: "Let's count."

As an aside, while outside passed pawns are very nice things to have, how did you actually intend to get one? And how many moves will it take you? You know Black is queening in 8 moves, right? You were extremely fortunate to come out of this with a draw. 37.fxg4 was killing
