I think we need some clarification of this -
ie we either accept that they happen , and allow a take-back.Mouse-slips
It occasionally happens, especially if you are new to playing chess on the Internet, that you accidentally let go of the mouse as you move a piece and it drops on a square you did not intend it to go. If it is obvious that that is what has occurred, you can ask your opponent to takeback the last move eg takeback 1 or perhaps even takeback 2 if your opponent has snaffled a queen or something the instant it plopped on the wrong square. Generally, your opponent should allow the takeback if it is obviously wrong and then you make the correct move. If you or your opponent feel that the takeback should not be allowed, you should check with one of our admins who are online – to do so however, is not so easy since as a default we have created these accounts with quietplay set to 1; this ICC option means that you cannot tell to anyone during a game or receive messages – as soon as the game is finished or adjourned, you will then be able to see messages in Channel 1 and channel 369 etc. To enable you to ask for advice from say the admin ausnetchess while playing the game, type on the main console quietplay 0 – this will turn quietplay off – you can then tell ausnetchess – I think I need help about whatever is the problem.
Or everyone gets told "tough bikkies" and live with it.
Because ACT players have "allowed" take backs, and are not being afforded the same courtesy. And it places unfair pressure on any child to make a "judgement call" on whether to allow a "takeback" when they have an obviously winning position as it stands.
