En passant

How can I apply en passant moves?

Does  it work automatically when I click on the figure to move, or do I have to do any other extra move on the display/computer keyboard, in order to enter that move?  

Works automatically.  Just move your pawn to the correct square and your opponent's pawn will dissappear.  All the usual rules apply.

I tried to do this, but it did not work in several games. Why?

your opponent pushed a pawn two squares at once, on the very next move you tried to take the pawn with another pawn as if it had moved only one square and the software wouldn't let you do it?

Let, I explained about it after your comments in the other thread about this topic.

Does anyone have the pronounciation glyphs for "En Passant"?

Is it pronounced "On Pasont"?

Could be. But nobody says "en passant", neither "j'adoube" here. There are Spanish equivalents.

I'm pretty sure the t in passant is silent .

maybe you could not have done En Passant because it is automatic
