//then the check algorithm

//then the checkmate algorithm

// for en passant check if current piece is pawn, if last moved piece was pawn and that pawn is adjacent now.
//On the other code I should've had the the endangers king called based on turn as a method of king only an used self.


//add a way to store piece just clicked on so if clicked again it's no worries
//some methods could've been subroutines

//make attribute variables private, so variable usage can be accurately traced


//I've added game over and castling(fingers crossed) and restart button. make sure to remove excess hashtags or slashes and print
//statements
//the castling gets a bit messy in terms of eval and accessing attributes without using a function.
//around line 697 and of course... 854!
//there were a couple of functions that had to be copied, so further forward thinking could've been used to avoid
//the problems. I could also have made code simpler and used less if statements.
//line 1312 look at comment
