McDonnell fights back. In an era of all-out attack his game is built on resilience: solid setups, stubborn defence and counterattacks that arrive exactly when the opponent's initiative thins.
Against him, an attack that looks winning has to be carried through precisely. He keeps finding defensive resources, and half-finished assaults are turned around with interest.
Regular games against McDonnell teach the value of resistance. You learn to press without burning your position, to recognise when an attack has passed its peak and to switch from defence to counterattack in one move. The hero of 1834 rewards patience as much as courage.
A single game shows part of the personality. Repeated games reveal more: you begin to recognise familiar structures, recurring plans and the kinds of positions this opponent prefers. That is where the collection becomes interesting, because different personalities put different questions to your chess.
Alexander McDonnell was the strongest chess player in England and Ireland in the early 1830s, trading wins with the best players of his era. His fame rests almost entirely on the extraordinary 1834 match series against La Bourdonnais in London, six matches totalling 85 games, played over many months in the Westminster Chess Club. Despite losing the overall series, many of his games showed tremendous creativity and fighting spirit. He died just one year after the match in 1835, likely from diabetes, at only 37 years old.
Notable: Game 16 of the 1834 match, where McDonnell played the King's Gambit Accepted with stunning complications, is considered one of the masterpieces of Romantic chess.
