He could have captured Gina’s piece that put him in check and that would have put her in checkmate, but that usually happens late in the game when there aren’t many pieces left and usually it doesn’t happen because the person checking them will know that it is a terrible move.
I have lots of experience in chess and I know that it’s really rare for something like this to happen, mainly because the person (in this case Gina) would be smart enough to know not to do a move like that.
It is possible to checkmate your opponent like that, but it is fairly easy for many people to not make that mistake. If Gina really is good at chess, she would have been able to avoid a mistake like that. Still a funny comic strip. She had it coming!
I think that counts as child abuse.
