over the board underpromotion
Sort:
In online chess when you want to underpromote it is easy. But what if when playing over the board there is a very rare opportunity to win the game with an underpromotion to a knight but you still have your 2 knights on the board. Where would you get the third from?
Write Knight on a bit of paper and weigh it down with some loose change. The list is endless.

If you have a second chess set laying around, then use that knight. I like Mark Grubb's advice too!
Be creative! If you are into modeling clay, then make a clay knight!
Or use an upside down rook for the third knight. Put a piece of paper on the upside down rook and say the piece is a knight.
What do they do in professional tournaments? If this circumstance had ever happened

Arbiter would generally have spares to hand. In FIDE rated events you're allowed to temporarily stop the clock mid-move while the desired piece is found.
I pulled the Albin countergambit trap (for those of you who haven't seen it before, this link should suffice: https://en.wikipedia.org/wiki/Albin_Countergambit,_Lasker_Trap) in a USCF rated game a few months ago. For this tournament we used our own boards as the organizers didn't provide them. As a regular Albin countergambit player, I have a 3rd black knight prepared with my chess set for this eventuality. However, the game was on my opponent's board so I moved my pawn to the promotion square, stated my intention to promote to knight, and then got a knight out of my bag and replaced the pawn with it. Then, an important detail, I only hit my clock after all of this was completed. Unlike some pawn promotion situations to extra pieces, I didn't bother to stop the clock. This was a classical game and I felt that if I couldn't win with 30 seconds less with well over an hour on my clock after the Albin trap I deserved to quit chess.
