pawn didn take

Why can't pawn take on c2 20 move ?

Because that's not how en passant works. https://lichess.org/learn#/15/3

Yeah, this isn't en passant. See https://lichess.org/learn#/15

Basically, you can take it while the pawn is passing f6 on the way to f5. You cannot do the same on f7, it's not passing this square.

Look, I don't wanna point out the obvious, but that's a 'you' problem.
If you're frustrated, take a step back and do something else instead of whining about it publicly and ridiculing yourself.
Please take this as life advice, because this doesn't reflect well on you.
All the best to you.

Well, must have been fools, obviously.

But judging by your (and four other) reactions to my post, some chess players sadly lack sense of humour ;-)

Chess players have a lot of opinions about themselves
