Taking back a move
Sooner or later, while playing online, we all will have to deal with undos (i.e. taking back a move). It might be because the move was a misclick or because the move was a bad one. My understanding is that taking back a move would result in an immediate loss in a Go tournament.
I stick to three basic rules.
- It doesn't hurt to ask for an undo.
- My opponent is under no obligation to grant me an undo.
- If my opponent doesn't grant the undo, just play the game as it is.
This topic came up with a reader after an online opponent swore and cursed at him when he refused to grant an undo for a supposed "misclick". The correct move that the opponent wanted was five intersections away. In the end, the opponent escaped.
I've had a number of misclick incidents where my stone landed next to the intersection I was targeting; resulting in a hane, or kosumi, instead of a tetchu (and vice versa). Often, I just play the stone where it landed. A couple of times, I've asked for an undo and been granted it.
On KGS, I've since turned on the mouse anti-slip option. According to Sensei's Library, this works by requiring that your pointer be immobile by several milliseconds before the click is accepted.
I can think of a couple of reasons why one might want to grant an undo.
- It's only a game.
- The error would dramatically swing the game in your favor and make the match uninteresting or unchallenging.
I can also think of a couple of reasons why one might not want to grant an undo.
- Rated games should be taken seriously by both parties who should apply care and patience when placing their stones.
- "No Undos" was among the explicit conditions stated in the match.
Part of the reason behind "the great undo debate" is that Go servers calculate your rank based on rated games. In a certain sense, a rated game could be viewed as equivalent to a tournament match. Obviously, it's a lot easier to grant undos in unrated games, and most club games, where the outcome has no bearing on your rank.
