Improving calcualtion in endgames
Hey, I (1800 OTB) was wondering if someone here has resources how to specifically improve good calculation in playing endgames. I always considered calculations (in middlegames) to be one of my strength and I always have very good results when I have to calculate in very sharp positions. I do train this a lot by solving lots of puzzles. But a game I played a few days ago really made me realise that I somehow am disgustingly poor in calculating endgames: I few that with puzzles from sites or even from books you never really train this but still it feels like an important skill to have for me.
In this game I (1800) drew a 1400 in 80+10:

Of course there are lots of opening and middlegame mistakes, but I specifically was disgusted by how many calculations mistakes I made in the endgame ensuing from move 29. WIth still some time on the clock (for context I had around 20 minutes when the endgame began, 15 minutes on move 31, 9 minutes on move 34 and someone else started notated for me after move 41 so around then I got under 5 minutes, but if I look at some 1100 elo calculation mistakes I made it feels like I was playing on increment the entire game) I made the following huge calculations errors:
- rejected 31. Bxe4 because I felt like after Rxe4 I had to play cxd6 where after Rxc4 my pawns felt weak, but I completely missed c6 instead of cxd6 winning completely)
- while even thinking that I didn’t need to hurry with taking the pawn with 32. Rf1 I somehow tought why not do it immediately: didn’t even consider any other move and c5 just wins instantly, also I missed that I have some problems getting out of the pin after Rf1 Re3;
- completely miss 37. Rh4 with still some time on the clock and immediately go for this check and go back trick, where I also missed by now 39. b4 would attack my c-pawn (just tought by then it was not possible as it hung a pawn); at this point (move 37) I was feeling very confident and it did look quite good
- after 39. b4 (I was now a bit low on time, but still now in huge time pressure) I panic and completely tunnel visions on a ton of lines where we both trade all the pawns, but I am seeing a lot of lines where I might have to go in 2 vs 3 on kingside bc my f-pawn feels weak and was feeling like I was completely throwing this while I was completely winning; this was all because I completely missed this 41. c7 move
- and at move 41 I not only miss trivial c7 winning instantly I don’t even consider Rxf7 and think I am losing if I don’t trade and then it just becomes a dead draw after trading
So to conclusion: does someone know any ways how to improve calculations in such endgames (like I said currently most of my calculations is just solving middle game tactics but I don’t feel like this gives me enough to be able to calculate in such endgames as it just feels very different).
