All pieces are back to the right way the shouldm except the king. I know have some super clean funktions, that should make position calculation extreamly fast. I also heard about some optimizations with shifting bit array, to make the movecalculation for a sigle piece even faster. Not really shure how that works jet, but I am planing on implementing that to in the futer. The faster my legal moves calculator is now, the better the engin is gona get later on.
