Scandinavian defense madness

Hi! I just browsed the chess explorer for Scandinavian defense versions, and saw that there was a move chosen by few to NOT move the queen after e5 d6 exd6 Qxd6 Nc3... But c6?! And after that, there were hundreds of moves people had done (how is that possible?) NONE of which was to grab the queen work Nxd6.... If this a bug?

I do not understood what are you asking check you move order and moves and share them on board and then I would see

It's because chess.com's database is silly and counts transpositions. In the position after 1.e4 d5 2.exd5 Qxd5 3.Nc3 c6 obviously everyone would play 4.Nxd5, but 4.d4 transposes to a position that could have been reached either through

1.e4 d5 2.exd5 Qxd5 3.d4 c6 4.Nc3

Or

1.e4 c6 2.d4 d5 3.exd5 Qxd5 4.Nc3

 

This is the exact same position, and obviously these reasonable moves have been played more often than the queen blunder move-order, so chess.com shows 4.d4 (and other moves) as more common.

If you use the lichess database instead (which does NOT take transpositions into account), you will see that indeed 4.Nxd5 is by far the most common move.

 

 

Another example is after 1.Nf3 e5, obviously white can win a pawn with 2.Nxe5, but since 2.e4 transposes into 1.e4 e5 2.Nf3, the database falsly shows 2.e4 as the overwhelmingly most common move.

 

Just one of the many reasons I hate chess.com's opening explorer.

Ok ya that's  true anyway lichess database is better than chess. Com

Oh that's interesting. If that's the case then I think it's similar to how the Chessbase database works.

Lichess' opening database only shows moves that have been tried in that exact position.
