K+3P endgame tricks.

I've picked up quite a few tricks to work out endgames with 1 or 2 pawns. The following techniques save lots of thinking just by using the high level concept to chose the move

* Opposition
* Shouldering
* Occupy the corner

But now I have moved up to king and 3 pawns I find that I have no useful rules and consistently make mistakes. Can anyone suggest the right high level concepts?

I use this to test myself, so far my high score is 3/10.

Just so you know, K+3P usually means one side has three pawns, the other none.

The example you have shown is K&2P v K&P - so it is was a little confusing with the title.

a bunch of the endgames have a wrong computer evaluation:

i'll post if i find more

Well spotted @qkxwsm . I've added few more on your thread. How well did you score in spite of the broken ones?

me:

1p -> 9/10
2p -> 8/10
3p -> 3/10

a real cliff edge I'm trying to get around.

Lol I tried it once and got 6/10 in a round where there was one bad puzzle.

Ditto, I'm failing these pretty badly (6 / 10). But it's before sunrise so maybe that's OK...

I got 8/10 but the last one: lichess.org/6TLNgLj1#114 was incorrect, so basically I failed at one puzzle. It was a nice experience as I had to think hard at some points.

This one is buggy:

It is not a draw, white is winning 100%.

Same goes for this one:


Black is winning 100%.
