okay so really enjoyable app i had fun but i have a problem with the concept that it doesn't let me. figure out a strategy of my own in a way, whenever my king is being threatened and there's a piece nearby that could do something about it it doesn't let me. play it. I am being forced to either play another piece which i don't want to use at the moment or play the king in a position that may or may not help.. It sucks cause sometimes i lost games just like that. I would have preferred to have more free will on my choices
