"IF" Players can put pawns on the board randomly. but it can't ensure that every pawns is on the legalMove() of previous pawn.

I'll fix these problem in one week!

• Sorry! I pay more attentions to detail!
• x,y refer the COORDINATE of the chess, 0 &lt =x,y &lt 4
• direction:"UP" "DOWN" "LEFT" ""RIGHT" , string
• legalPos(): generator
• Board.putChess is useless! but it does exist, so I put into description(maybe I should cut it off?)
• I'm busy these days! I have to prepare final examination.Sorry :(
  

Sorry, maybe I didn't narrate clearly :P
