Plz make more than 1 moves because i want to play with the computer longer
You can put your Castle at c8
That's impossible.
Rf1 is just mate in 1
move your rook that's closest to the king somewhere else so the king can move so it won't result in a stalemate, then just move the pawn near the rook up until it becomes queen
checkmate
Rh2,Kxh2.
Ng2,Kxg2.
Rf2,Kxf2..... Etc you get the idea.
