Opening trap #2

Scholar's mate. This mate won me a lot of games untill I started playing with people who are above 1100 rating. They knew how to get out of it and it did not work anymore..this is a well known motive..that could win you a ll ot of games

White tries to deliver checkmate with Q and B on f7. Back tries to prevent it by playing  Nf6 but it does not matter because Q can still deliver checkmate.
