Wouldn't it be nice to be able to analyze that move if the en passant rule was available on the analyze board feature. Like a big red flag would pop up or something to remind you. But then again that might be almost as bad as discussing a game that is still ongoing.😕

I think we need other information it should tell you which of your pieces are hanging or en prise.

yeah that en passant will get you every time

Is this not a player asking for (and getting) advice on a game in progress?

Have I missed an announcement that this is acceptable now?

NO! I'm not asking for advice on my next move, I'm asking why I haven't been awarded the game..!!!!!!!!!!!!! Mikey Boy! 😀 🙄

I still don't understand why that isn't mate.
Could somebody explain better pleaze..?
What is the en passant rule?

EDIT:
Don't worry! Found it!

EDIT:
But isn't the en passant rule only for pawns?

There are pawn involved, aren't there?

Maybe I don't understand the rule quite clearly...

This is turning into a comedy 😵
