Just started watching the first game. Why did you retreat your g4 bishop to keep the pin? This allowed him to play Jobava London style pawn storm. Remember that’s your bad bishop, and you should exchange it with the pinned knight, as that also removes one of the defenders of his d4 pawn. Time to refresh the exchange variation theory 😀. Watch Alex Banzea’s video where he has the rule of thumb of when to take the knight (if opponent already played Nc3 or Bb5).
