@AbigaiII It's my own idea, I tested it in some blitz game with a friend. It seems to be similar to normal chess, but there a few new possibilities, it's intersting. I like it...

Hi, I developed a New Chess Variant, I want to suggest (I call it "Capture-Chess"): There are the same pieces and the same board like in normal chess, but additionaly it is allowed to capture own pieces. If someone captures his own king, he cannot be checkmated. But then he has to checkmate the other in a maximum of 50 moves (this is of course variable, but I took 50 in analogy to the draw-rule of 50 moves), otherwise he is lost. If someone has already captured his own king, the opponent may not capture his own king.
