, wherein each human player uses a computer chess program to help him explore the possible results of candidate moves. The human players, despite this computer assistance, are still fully in control of what moves their "team" (of one human and one computer) make.

Many Advanced Chess proponents have stressed that Advanced Chess has merits in:
  • increasing the level of play to heights never before seen in chess;
  • producing blunder

A variation or superset of Advanced Chess is freestyle chess, where consultation teams are also allowed. It is common for "regular" Advanced Chess single man/machine teams (also called "centaur play", to differentiate between pure-man or pure-machine play) to take part in freestyle tournaments. Freestyle tournaments are frequently more informal than regular chess tournaments, even though the level of play can be significantly higher.

History

The concept was already common in the 1970s: "An interesting possibility which arises from the 'brute force' capabilities of contemporary chess programs is the introduction of a new brand of 'consultation chess' where the partnership is between man and machine."http://books.google.com/books?id=c-Pp2pmz328C&lpg=PA330&dq=new%20scientist%20chess&hl=es&pg=PA332#v=onepage&q&f=false

In such a short match, against a very solid and hard to beat opponent, this turned out to be too much but I don’t really feel like that the computer alone can change the objective true to the position."
