What Lurks in My Database?

    
There are millions of games in my database and who knows what’s lurking in it? The other day I started poking around and playing through games at random. One of the first ones I came across was between La Bourdonnais and McDonnell. This game ends with a comedy of errors, but the mate with two Knighss is pretty nifty.
    Louis Charles Mahe de La Bourdonnais (1795-1840) was a French master who was possibly the strongest player in the early 19th century. La Bourdonnais was born on an island in the Indian Ocean and learned chess in 1814 and began to take the game seriously in 1818, regularly playing at the Cafe de la Regence. He took lessons from Jacques François Mouret (1780-1837), his first teacher and within two years he became one of the best players in the Cafe. Mouret was a French master of the early 19th century and the chess tutor of the future King Louis Philippe I. 
    La Bourdonnais was forced to earn his living as a professional chess player after squandering his fortune on bad land deals. He played before a World Championship was established, but was considered the strongest player in the world from 1821 until his death in 1840. 
    The most famous match series (totalling 85 games) in that time was the series against Alexander McDonnell (1798-1834) in 1834. McDonnell was an Irish master who eventually settled in London, where he became the secretary of the Committee of West Indian Merchants. It was a lucrative position and he became wealthy ny advocated strongly on behalf of slave owning sugar plantation owners. 
    In 1825, he became a pupil of William Lewis, who was then the leading player in Britain. But soon, McDonnell had become so good that Lewis, fearing for his reputation, simply refused to play him anymore. McDonnell was suffering from Bright's disease, the old name for acute or chronic nephritis. In the summer of 1835, his condition worsened and he died in London on September 16, 1835. 
  A game that I liked (Fritz 17)
