during endgame, no extra queen?

What would you do? During the endgame, your king is beside your pawn on top of the board during the endgame. Your pawn is about to reproduce a queen, but you don't have any extra ones on you.

I always used an upside-down rook.

how

By turning a rook upside-down.

I usually stick a bogger on the board. If I want to move the bogger(queen) I clean it and use a fresh one. If I'm out of mucus I politely ask some from the audience/opponent.

Right. Ordering upside-down rooks is a waste of time and money.

I put on my Martha Stewart apron and make my own upside-down rooks!

Inverted R is common. Otherwise, a bottle cap, pebble, coin or whatever is at hand suffices rather well.

You kind of lost me here.

Why not just pull back the pawn to prevent promotion until another queen is available?

Get a salt or pepper shaker. Be creative.

Your logic is impeccable, but maybe chess isn't your game.

are you joking like the woman that got fired at the mm factory for throwing out all mm that said ww.

Or the carpenter who ran out of west-facing nails, because he only had east-facing nails.

Well, there was a time when chess sets didn't come with an extra Q. So, you improvise. An inverted R is probably the best choice (if avaiailable). Otherwise...bottle cap, pebble, button, or whatever (as I've said before).

What part of this don't you comprehend?

This is the same guy who said he wants to sue a grandmaster for not giving him lessons, because it violates his "rights."  He's either a troll or mentally... disadvantaged.

Seriously, do you really believe he doesn't understand the concept of turning a rook upside-down?  Don't waste too much time or effort on it.  

XD

"This is the same guy who said he wants to sue a grandmaster for not giving him lessons,"

Yeah, now I get it. The OP is really just a cockatoo.

Wow, seems we all have alot ot learn here.

Mostly just one of us, by the looks of things.
