I should note that my thread title is misleading: sometimes I do not lose in endgames, sometimes I just lose my winning advantage and escape with a draw.
always losing in endgames
There is nothing wrong with your moves 27 thru 35. You have covered your weak pawn h6, and your rooks are active on the f-file and even have options on the third rank. The position is completely equal.
35.-R3f5 is not yet a mistake, but it takes your active rook back without necessity. Instead, you can further increase the activity of this rook with 35.-Rc3 or (this would be my preference) 35.-a5 with the plan of advancing this pawn to a4 and cracking up White's queenside pawn formation.
After 35.-Rf5 36.Reh4 you could still return to the active outpost with 36.-Rf3 and an equal position. Only after the blunder 36.-Kg6?? your position became hopeless immediately.
Hi,
I'm very bad at endgames. Let's take this game for example, starting from move 27 when we got into a R+R vs R+R, 6 pawns each endgame. The time control was 5 1. It is by no means a good game.
Of course I made quite a few obvious blunders but the main problem I had was that I didn't know what the correct course of action was. In a longer game with more thinking time I would have avoided giving away so many pawns for free, but I would not have been able to form a good plan. My a6 pawn was obviously weak and he was obviously going to try to exploit that. As a countermeasure perhaps I could have pressed on c2 or b3 (assuming he'd played c2-c4 or something like that)? My king was close to my weakness, which is good, but I remember my coach (back when I had one) would always say, in an endgame always attack, attack and never look back. I wonder how that could be implemented here?
