I have a question about the rules, I am not sure about the en passant rule.
The following rule is described:
'On squares passed over, the pawn can be taken en passant.'
Does this mean, if the pawn makes an initial double step en passant is
like in orthodox chess?
In case of an inital triple step, for example b2-b5, does it mean black
pawns a5, c5 could move to b4 taking away b5 OR black pawns a4, c4 move to
b3 taking away b5?
It could also mean a5,c5,a4,c4 all must move to b4, though I don't think
so.
Thanks in advance for a clarification.
