You just kept missing win after win. For instance 31. R1e6+ is easy to spot and wins very easily but you swapped pieces off for some reason. Just practice more. Your opponnt played badly and was lucky. You played quite well but missed important moves.
yeah R1e6 isn't a natural looking move to me, I was worried about time because I lose often on time and worried about getting caught in some weird back rank mate or something. Sometimes I do checks only to find no follow up and lose a piece too so sometimes I am careful to give a check sometimes too esp if I am several minutes behind on time, I can see it would have been a difference maker, I'm sure in a classical game or a puzzle I could find it
I'm sure you are right optimissed, I miss a lot and really no clue how to fix it, it is definitely not intentional. I recently bought a guide that has you do lots of tactics and slow down, but I'm slowing down too much and still missing everything, then feeling insane afterwards. I've played for over a year at this point, I am in my 40s so maybe too old and dumb. I was a good athlete as a kid and did jiu jitsu for a long time as an adult until injuries caught up with me. Chess gives me the mental stimulation those things did but none of the physical outlet at all which kills me because I want something to take it out on so bad. All 4 of those loses 2 days ago I was up material down on time and they pull a rabbit out of their hat, seems impossible everytime
