A Bristol-like line clearance in which one of the thematic pieces is a pawn or king, rather than a line-piece. Two cases can be distinguished:
1. A non-line-piece (pawn or king) clears the line for a line-piece in two or more steps;
2. A line-piece clears the line for a non-line-piece (pawn or king).
The idea was suggested by Aleksey Oganesyan in the RU-Chess-Art blog (as pawn-Bristol). The term Pseudo Bristol was coined by Viktoras Paliulionis for more general case.
