[what is this?]

Chess exotica Strange and bizarre games. 2 games, 1839-1998 Early examples of back-rank redeployment Steinitz usually gets credit for introducing the concept of retiring his pieces to the back rank for strategic purposes. I have tried to look for earlier examples, often involving Paulsen. 6 games, 1862-1869 Early positional exchange sacrifices Here I try to collect some examples of early, positionally (not tactically) motivated exchange sacrifices. 2 games, 1749-1843 Mind over matter Games where one of the players sacrificed material (preferably lots of it) for unclear or long-term compensation. 6 games, 1981-2004
