en passant étiquette when opponent doesn't know about the rule

Quetion: When playing an opponent OTB who does't know about en passant, and you use it, then he/she protests, should you...

1. Let them take the move back?

2. Let them keep the move but agree to refrain from using en passant (just this once)?

3. Insist your move should stand since it is a legitimate rule?

4. Get into a shouting match i.e. "That's not a real rule!"

"Yes it is!"  "No it isn't!" "Yes it is!" etc. ect.?

5. Get up, take two steps backward and one to the right, and burp loudly in a northeasterly direction?

 6. Start commenting on Tactics Trainer that every problem is "en passant"?

#1 and let them know that you will use en passant again plus #5 as a follow up.

in tournament I call TD and he takes care of it. I don't take it back. on friendly game, I explain that is an actual move on the kind of chess I play, then I take it back and play something else.

Thank you for you comments, 2714kkw and hthtdavid.

This situation came up in a recent casual game, and we agreed on option #1.

#6 definitely

This thread will reopen in seven days.

If you don't know the rules, read them... Its kinda of important when playing a game.  Did he get pissed off when you Castled?  No... So why would using the en passant be any different?

Sorry, folks, this thread is temporarily under construction.

It will reopen in seven days.

I will, however, soon create a thread about why en passant is the last rule most players learn.  Please refer to that, or any of the other many lively threads about en passant elsewhere on this site.

Sorry for the inconvienience.

Think you have to be a little sensitive with complete beginners - I occasionally have just a silly game with friends/family who don't really know how to play properly but at least know the basic moves. But there are some things you can't expect them to know, and en passant is one of them. Other things include e.g. that you can't castle out of check, or castled over a square that is under attack by an enemy piece. I usually let them take the move back, and explain the fact that there is actually a rule which covers it, and just let them move again. The castling out of check issue is a funny one though, because if someone has allowed themselves to be checked in the expectation that they can always castle out of it, that might ruin their whole plan. I've occasionally let people get away with that one, but only if it's someone who clearly has no intention of ever trying to play chess seriously. If they are starting out at the game and want to get better, obviously you have to explain the rules to them!

I avoid such situations by not using en passant, which is very much possible. If someone doesn't know the en passant rule, then chances are he's a very basic beginner, and I can easily beat him anyway without taking advantage of the rule.

Look at that...no one bothers to comment for days, after over a hundred views.  Now the thread is getting hits.  Mabye the best way for a thread to survive is to try to kill it.

For those of you who don't know what I'm talking about, please refer to macer75's "thread killer game".

Move along, folks, there's nothing to see here. 

#3 definitely.

Learn the rules.

If I'm playing a friend maybe I let them off.

# 3 obviously, ignorance is no excuse.

In fact it happened to me in a club game when I was playing chess for a few month. After some arguing and many people telling me "yes, it's a rule!" I hastely accepted since his taking e.p. was in fact a bad move, lol.

(#5 , you mean northwesterly direction I suppose)

General-Mayhem started it 57 minutes ago, blame him.

Exactly. 

Excuse me for not checking when the thread was started, only the latest comment...

Well, since this thread has been apparently resurected by an attempt to kill it, I guess I'll say why I think en passant is the last rule most players learn about.

I think that when being taught in a friendly setting, a very beginner finds it quite daunting to even learn how the pieces move and interact.  Throwing in  yet another rule that rarely comes up in beginner games might actually dissuade people from continuing the pursuit.  If the teacher has only been a casual player, and his/her teacher was also, several "generations" of casual players may play all of thier games and never even learn of or encounter en passant.  Even if one of the plyers knows about the rule, it is obviously not always the best move, so it would still not come up.

So, generally it's not the fault of the friendly player.  He believes he has been taught all the rules.  And as macer75 pointed out, one can play quite competently without it.

Also, just to clarify what john4000 was saying, one can castle over a square under enemy attack, as long as the king does not move through check while doing so.

With that said, I hereby officially KILL..THIS ...THREAD!!!!

Bye.

P.S. @General Mayhem you are the only one who commented here today before the thread killer game began on this thread, so you are off the hook. 

3. Insist your move should stand since it is a legitimate rule

If you play any game, you should know the rules beforehand.  Chess isn't like Monopoly where there can be any number of "house rules," except maybe for agreeing to play touch move, timed vs. not timed, etc.  But the basic move rules are the same around the world.  Not knowing en passent means they need to bone up or else need to learn it ASAP.  I think anyone I've ever played OTB was advanced enough to know the EP rule.  If someone were a complete beginner that might be a different story, but like I said it would be time to learn the rule.

And in this day and age where we have the internet accessible virtually everywhere and at our fingertips, it wouldn't take long to google it to find out it's an actual rule.
