It looks very well played. Did you use computer assistance? Just asking because you said its a practice match, and I don't really see blunders. Long game and I didnt look that close but still, if you didn't use computers in any way, looks like a very nice effort.
13. b3 & 19. f3 felt a bit off.
Hello! this is a practice match I played OTB. My opponent choose an unusual Benoni variation to play. I think I was able to get a good advantage throughout, which accumulated to a significant material advantage but it seemed pointless as my opponent was able to set up a fortress (is it a tablebase draw?). I offered a draw as I was close to flagging in the end. Could I have done anything better leading to the endgame? I was thinking that I may have oversimplified, but I would appreciate your analysis
