Game IV of the even-terms Morphy–Paulsen match (First American Chess Congress, New York 1857) — a Sicilian Opening, Morphy (White), drawn. Notes from the 'Book of the First American Chess Congress,' with the Editor's additions.
5.Nb3The move of 5. Q. B. to K's 3rd, adopted by White in subsequent games, is the best at this point.
7.Bf4This move compels Black to weaken his position by advancing 7. P. to K's 4th.
17…Nd4Well played.
19.Qf5White evidently could not capture the Q's P. with Q. or Kt., as Black would have replied with B. to K's 4th, and so forth.
24…Rfd8The correct move. From this to the end, Black plays capitally to effect a draw.
35…Kg835. K. to R's 3rd would have lost the game.
36…Bxa1And the game was drawn. The position is a curious one. Although White has two Pawns more than his adversary, he can do no more than draw.
