|Breton:||When a unit is captured, one other unit of the same type as the capturing unit (if any are present) is removed at the same time. If more than one such unit is present, the choice of which is to be removed is made by the capturer.|

(C+ by Popeye 4.87 & WinChloe)
Moves like e7*d8=B[-wBd8] are only accepted by Popeye, but not by WinChloe. At the time of the Breton removal, WinChloe considers the promoting pawn to still be a pawn; it can therefore not be a Breton victim as part of the capture of a bishop.
Since Christian Poisson invented Breton, WinChloe is the reference here. The French have coined the term "Breton Py" for the way Popeye does things.
