Moheschunder Bannerjee (Bengali: মহেশচন্দ্র বন্দ্যোপাধ্যায়, fl. 1850) or Mahesh Chandra Banerjee was a strong chess player from Bengal, many hundred of whose games survive through the writings of John Cochrane, who regularly played Bannerjee between 1848 and 1860, during Cochrane's tenure at the Calcutta bar. His first name is sometimes misspelled Mohishunder, though Mahescandra is a variant. Banerjee is a common Bengali Brahmin surname.
Moheshchunder, also known as "the Brahmin", was a player from the mofussil or suburbs of Calcutta. He played traditional Indian chess, which in Bengal at the time, pawns did not have the option of moving two squares from the starting row and pawns would promote to the piece of the square reached. Also Bengal chess rules did not have castling, but an unchecked king could execute a knight's move once during a game. However, there is little difference in the middlegame and many Indian chess players were very strong tacticians. Bannerjee is likely to have transitioned to western rules after contact with Cochrane and other Europeans.
What little is known of Moheschunder comes from articles that John Cochrane, stationed at Calcutta in the 1840s, wrote for the London chess magazines. It appears that Cochrane, who had defeated every player in England barring his protégé Howard Staunton, had been searching for some worthy opponents for some time. In the autumn of 1848, a member of the Calcutta Chess club heard of a Brahmin in a village (mofussil) who had never been beaten at chess. He found an opportunity of meeting him, played him, and lost. It was stated that the man, 'Moheschunder Bonnerjee, a Brahmin', of about 50, hardly knew the European rules of chess; yet his play was presumably under European rules.
This club member brought Bannerjee back to Calcutta with him. Cochrane played him and won, but was impressed. Banerjee was engaged as "a paid attaché" of the Chess Club, where he improved wonderfully. In the Chess Player's Chronicle for 1851 are published some games between Cochrane and Moheschunder; and "the Brahmin" figures as a player in various collections of games. The Indian Defences by P-KKt3 coupled with P-Q3, or P-QKt3 coupled with P-K3, were largely taught to European players by the example of Moheschunder and other Indians, to whom the fianchetto developments were a natural legacy from their own game. It is notable that many of Bannerjee's openings were based on single pawn moves, the "legacy" mentioned by Sergeant, as in the rules of Indian chess.
Cochrane is quoted in a letter written by a member of the Calcutta Chess Club, appearing in the Chess Player's Chronicle in 1850:
- The only player here who has any chance whatever with Mr Cochrane, upon even terms, is a Brahmin of the name of Moheschunder Bonnerjee. Of this worthy, Mr Cochrane has himself remarked that he possesses as great a natural talent for chess as any player he ever met with, without one single exception.

The origin of the name "Indian Defence"
Moheshchunder, like other Indian players of the time, favoured fianchettoed openings, trying to control the centre with long-distance pieces rather than occupying it with the pawns. Possibly these ideas germinated in an environment of chess rules that did not permit the initial two-square move for pawns. The theory behind these openings were developed in recorded chess history much later, but Cochrane introduced the term Indian defence for this class of openings, which has now come to cover the Nimzo-Indian and many other popular openings. Fianchettoes appear to have been a favourite style in Indian chess variants, and the Queen's Indian defence was also a frequent opening for Mir Sultan Khan, who visited England for five years and won the British Chess Championship in 1929, 1932 and 1933.
