[J] To enslave the Rook.
[K] An excellent move. In this and the succeeding moves, White played very well. His efforts were directed to saving his R., but, as the result showed, without success.
[L] Apparently hazardous, but justified by the gain of time.
[M] We believe his best move.
[N] White was obliged to lose the exchange, although he fought manfully against it.
[O] Another very good move in White.
[P] Black's advantage in the exchange begins now to tell on the game.
[Q] Threatening mate if R. takes Q.
Game IV.—Played by Correspondence between New York and Philadelphia, in 1857.
