Draw by repetition

Just wanted to know what the draw by repetition is all about and how it works? What is considered a repetition? Thanks

if the exact same position occurs 3 times with the same color on the move the game is a draw. should be in chessopedia, but it's not.

 Not exactly... the draw is not automatic, but the player whose move it is can claim a draw at this point.

One more complication: The same opportunities have to be available to both sides for all three times the position is repeated, including en passant, castling, promotion, etc.

in tournaments it's not automatic but online & computer chess program(most) it's automatic.

Could you please show an example or just notate one, to see exactly what the 3 moves are!

(Crunch crackle) Early on, my instructor placed a cone in front of me and asked me to duplicate it on paper with a pencil. My first attempt looked more like a triangle than a cone. He said, “Now do it again.” My second attempt was better but still had the sharp edges of a pyramid. He said, “Better. Now do it again.” This process repeated for a month until I was adept at drawing cones.

These days, I am trying to master drawing butterflies. To most casual observers, my butterfly art would look quite professional. However, I know that I can do better depictions of monarchs. Practice makes perfect so I keep repeating the process until I have mastered the subject matter. Amazing that decades after taking a single art class, I am still a fan of drawing by repetition.

It's unclear to me which player this refers to. Does it mean the player whose turn it is after the move that makes the final repetition, or the player whose turn it is as they make the final repetition?
 
Also, regardless of which player gets to choose, here onChess.com I have been in both positions often enough to know that neither is offered a choice before the draw is declared.

I assume you're talking about three fold repetition.  When the same position appears on the board three times, a draw MUST occur. It's a pretty easy way to force a draw when you're losing and your opponent denies offered draw.

Note that, in order for a draw to occur, it doesn't have to be the same position three moves in a row. There can be intervening moves. But as long as the same position is reached three times, the player who has the move can claim the draw.
