Question: In Blitz (5-min Chess) your opponent puts you in check. You then make a move that places your opponent in check. Can your opponent still take your King and claim victory (even though he's in check)?

  • This question has been answered several times. Yes, the opponent can claim an illegal move (not necessarily a win though) and no, the opponent cannot take the king. – IA Petr Harasimovic Mar 27 '18 at 9:50
