how i can see that? well i don't study that how a theme of book, was more of see ends of the players, of see how the adventage transform in a end the whites win, sometimes say the whites win the end, then i played the end until win always, but take a consideration need tactics and a lot practice, above all in the end don't have time for think or is a bit.
is need take in consideration always the rule of cube if the king enter in cube the pawn don't promote alone ( if whites move the king in d4 don't can stop the promotion). this is important sometimes we can sacrifice pawns promote alone come back your game
My only endgame where I remain totally clueless is these king-pawn endgames with pawns on both sides. They are very difficult. I tried looking for chess books and videos but all of them only tells theoretical ones which I have already studied but not the practical ones with pawns on both sides.
How can I improve them. This is a game which I almost won but have to take only a draw due to blundering in final king and pawn endgame
