A Win by Resignation

Earlier this afternoon my opponent playing Black in this standard correspondence chess game resigned after my Bishop captured his Rook at 23.Bxc7, giving me the win by default. This only made sense: his army of Queen and Rook at this point was much smaller then mine of Queen, Rook, and Bishop pair. Technically he could have played on, but my material advantage was suddenly so overwhelming that checkmating his King was only a matter of time.

The final position of pieces and our full move record are included with this post.
