Pure checkmate ( English pure mate ) - a kind of chess checkmate , in which all the fields around the king are either attacked by the opposite side exactly once, or are occupied by pieces (or pawns ) of the same color as the attacked king. Pure Pat - A Pat that has the same properties.
The purity of the mat (pata) is not violated if the piece (or pawn) occupying the field next to his king is in a bundle , and this bundle is essential for creating a mat (pat).
A similar mat took place in the famous " unfading party " of Andersen and Dufren , held in 1852 .
If all pieces of the attacking side are involved in a clean mate at once, with the possible exception of only the king and pawns (that is, the mate is also economical ), then it is called correct .
