What has lichess done to me?

I just thought white losing their queen was just another typical lichess player blunder :(

Bc4 is a blunder, just not losing a queen. Qa5+ wins the knight.

Well, it was a typical blunder actually, but you took the wrong piece! ...Qa5+! at move 6 or 7

At move 6 it doesn't win the knight. Qc3 is another mate-in-one threat which doesn't work with the bishop at c4.

@irishsultan it works on move 7.
