how to improve my endgame technique?

i'm really disgusted... i always manage to play a strong opening and a nice middlegame .... so i obtain a winning endgame which i am not able to convert! yesterday i had bishop and 2 pawns against a bishop with the same colour , i blundered and it was a draw...i had also another position with rook+knight+2pawns vs rook+3pawns, i made many mistakes and it was a draw....how can i do to improve my technique???0

I'll be frank. There is no endgame Bible which makes you perfect any position, each position is different and requires tons of technique and thought. There are many endgame books out there which are extremely good at saying general ideas in general positions, such as, Drovetsky's Endgame Manual (RIP).

I would be happy to analyze a couple positions a day with you through Lichess's study feature which is perfect for approaching endgame positions. Whichever you choose just try to take one position at a time. Endgames are a great part of chess to sit down and divulge :)

you might get some help in here , check the link below and get a general idea of how endgames work.
However ,u should keep practising and make it to endgame(by exchanging pieces asap) , you will learn from mistakes by analysing your own games .

@nourhene you must prepare the advance of your pawns better by taking control over the stop squares (the squares in front of the passer).



In the first game this means you move your bishop, supported by the king, on the diagonal on which the opponents bishop controls the stop square of the pawn, but not on the stop square itself, as you need that square for your pawn. The opp then must switch to the other diagonal controlling that square, this takes two moves and you have the time to advance the pawn over the stop square without him being able to take the pawn. This is a common method in bishop endgames.



In the second game you first had to place your bad pieces, knight and king better, before you advance your pawns, otherwise they will at best be exchanged and exchanging pawns is nothing the player with material advantage wants. He wants to exchange pieces, not pawns.

When i look at the second game again, what the heck has driven you when you moved king to f8 and then back to g7? Kf7-e6-e5, game over. How can that be not obvious? The king is a mighty piece, use it.

Chessable.com has an interactive version of Jesus De La Villa's '100 endgames you must know' which is around $15 and a whole lot of book (really). If you'd rather not spend money, there is another endgame repertoire called 'Basic Endgames' which is extremely in depth and completely free.

I own Hawkins' 'Amateur to IM' and Silman's 'Complete Endgame Course' and have found the Chessable repertoires to be the most beneficial thus far.. I find the reading and repetition both instructive and therapeutic (also: I'm not affiliated with the website at all, just a fan).
