But thank you for the answer!:)

I think you misunderstood me. What I meant is if we can get a puzzle mode, so that other players can play a puzzle without seeing the answer. Like the tactics trainer.

Can we add a REAL puzzle mode in study? Not the hide all moves thing?

Is it possible to add the bughouse variant? Or, another kind of funky variant, like kung-fu chess, where there are no turns and you can just do anything? :)
