bishop from c1 to h6

if he takes the pawn at e5 from the pawn at g6
{ use the rook at h5 take the knight at h5
rook from h5 to f5 and take pawn
rook to f4
rook to e4
rook to e8
*note, even if we were to suppose he moved his pawns forward from f6&f7 as to allow his king an escape, you should be able to at least capture his rook. At such point, it is fairly simple to keep plucking out pawns.
}
else if he moves his knight from h5 to g7, {
rook to e4
rook to e7
rook to c7 taking pawn
rook to c8
}
else
{rook from h4 to e4 then
