This opponent beats me 99% of the time! I felt like he broke though the London on this one. But then he missed the Pin!! Check out this #chess game: Davitow vs xR3B3Lx - https://www.chess.com/daily/game/696934129
You should know the ones that can arise from your opening choice but don't rely on them, maybe only in bullet and blitz. For example i play the Old Benoni against d4 and there is a trap but the opening is still sound if they play well.
