I am trying to understand this game, but some of the moves are confusing. For example, black makes seemingly pointless bishop moves in which he gets challenged by a pawn and immediately has to move his bishop again. Also he has an opportunity to take what looks like a free knight. I would assume they are mistakes, but I know one of the players is FM Oleg Zaikov (23xx), and the other is Marcus Robinson (17xx). Marcus Robinson entered the match with a team lead of 4.0 to 3.5. So by drawing this game, he won the match.

Any guesses on which player is which? Also, are any of the moves (blacks especially), mistakes?

My guess is that the score is not accurate.  The bishop moves I can understand (attempting to soften up White's pawns on the kingside and get the d4 square for his knight), but Nxe6 just appears to be a hang.  It's probably not the right position/move.

He doesn't waste moves moving the bishop, because if black is wasting moves you wil have to consider white chasing around the bishop with his/her pawns wasted moves so it evens out right? Idk, making room around the king like that doesn't seem logical if you ask me. Like when i pin a knight to the queen (like black did on move 10) i welcome my opponent to chase my bishop away since it opens room around the king and in theory weakens my opponents positon.

Idk why black didn't take the knight, maybe because he/she was playing a 2300 and didn't think someone that high blundered? Maybe im missing something but it seems the psychological aspect played a bit part in black not taking.
