Rules

Hi everyone, I wondering, does my king can capture an ennemy piece if that piece is backed up by a knight, but this knight is nail ( can't move or he's king will be check.) thanks to all, excuse my approximative english and hope that it's understandable.

The king cannot take a guarded piece, because then the king would move into 'check', which is against the rules.

Yep, but the piece is guarded by a knight who's nail by one of my bishop...

Doesn't matter. Check is check. Pinned or not.

In such a scenario, your king would be captured before his would, so you would lose, and thus not allowed.

The piece that is "pinned", or "nailed" still controls the square that your other piece is on. Look at it this way; if you take the piece, then the knight takes your king and the game has ended before you are able to take your opponent's king;)

Ok thanks everyone
