Since he is in check and has to drop your pawn, he can't take : your opponent is mated.

As far as the aim of the chess game is to make sure that your opponent can't play without leaving his king in check, even if it seems logic, you can't move. So you're mated...

OK But by definition, check is the state where the opponent has a next legal move to capture the King.
Well, if the only legal move is drop a piece somewhere, no King can be in check.

It's checkmate, know that... Moreover, you can check without capturing. So the king would be in check and you could "take" the king (which is an illegal move by the way) if your opponent does not block it.
Hello Chess-Lovers,
That's my first post on the Chess.com forums so please understand this could not be as good as your ones.
My friend Zeolb and I wondered what would happen if capturing pieces was not possible anymore... We imagined a system where it is actually impossible but it was not that attractive : if you capture a piece, you must drop it somewhere on the board on your next move. Note that dropping a piece is symbolised by a "@" in algebraic notation.
But we thought this only rule was not enough for this game to be enjoyable. So with the new game, kings are able to capture pieces as they do with chess rules. And we started to play it. We learned tactics and many beautiful mates...
In fact there is one thing you should understand before playing interesting games : your opponent and you must drop on their next move the piece they just captured. That way you could mate your opponent really easily if he just captured a piece, not giving you check : check his king and this game will be a win for you.
1. e4 e5 2. Cf3 Cc6 3. Fc4 Cf6 4. d4 Cxd4 5. Fxf7#
Here, black takes d4 which is a fatal error : white can check him in one move, giving checkmate since black needs to drop the white piece and to stave off the check. He cannot do these two actions at once so that's a checkmate.
1. d4 d5 2. c4 dxc4 3. Da4+
Take care, that's not a checkmate here, black can still drop the white piece staving off the check with 3... @c6 or 3... @b5.
Obviously "classical" mates are still working but make sure that's a mate or your piece could be captured by the king and this would be sad for you.
You now understand the rules and these basics... Please think about it and discuss the rules, discuss tactics and strategies in the comments. Try out this brand new variant of chess games and if you really enjoy SwitChess, keep us posted ^^
Hoping this post will have pleased you
