(c3,c3) I didn't move because you are still in check. Put this move (d1,e2) in the quick reply box and make another move. You can only move your King or bishop. You only have one of four moves. (d1,d2) (e1,e2) (c1,d2) or (e1,f2) to get out of check
I see what happened - Cant put combinations in this box because they are carried out. I made a bunch of moves in my last comment and messed up the game....
You can re-add pieces by using the same command that you do to promote a piece (making the pawn a queen or rook or whatever when it reaches the end). See http://foru.ms/faq.php?faq=chess_main
