Mongredien against Morphy — the first game of their 1859 Paris match, a sharp “Double Gambit” (the Evans and the King's Bishop's Gambit combined). It was given up as drawn by mutual consent, the only half-point Mr. Mongredien secured in the contest.
3.b4A bold move, but one certain to lead to positions of high interest.
10.Ba3Well played, getting rid of the adverse K's B., and enabling White to Castle on the King's side.
12.O-OThe wisest course of play Mr. Mongredien could have chosen, for had he deferred Castling, he would have been subjected to an immediate and embarrassing attack by Black's moving Rook to K's sq.
14.Qf3Again a very well played move.
15…Qe7If the Queen had been played to her Rook's 4th instead, White could first of all have taken the Knight with his Bishop, and then posted his Rook at Q. Kt's 3rd.
25.Rxa7The exchange of Rooks would have been an unwise step, and White would subsequently have lost a Pawn if he had ventured on it.
