The opponents can accept or refuse an undo request

The software allows considerable flexibility, that is true. That does not prevent a TD from imposing additional restrictions by regulation. A possible suggestion mentioned earlier is that the opponent shall only accept or reject an undo request in accordance with instructions issued by the TD. Obviously this is in a tournament environment which has a TD.

Incidently,I find the 'undo' option unique...it would never be allowed in a 'real life' tournament(!)

That is not true. Law 25A1 is a case in point. Indeed I suspect that the undo button in online play is made available largely in order that the online game can simulate as close as possible the provisions of law 25A1.

Arguably, there is less scope for UI in the online game. A genuine misclick conveys no information about the clicker's hand. (Oof Arted has yet to respond to my challenge in post #29 on this thread - presumably because there is no possible response). By contrast in a real life tournament it is harder to imagine that the initial call contains no information.

I think that one of the earlier posters suggested that it would be for the TD to sanction or deny an undo request, not the other players at the table (unless they generously are content to allow it). TD will (alone) have sight of all 4 hands and can form an opinion on the misclick v change-of-mind conflict.

There's no TD at ordinary tables, only tournaments.

Agreed. The thread appears to be predicated on a tournament environment. And it is posted in the Tournament Discussion forum

Good point, I forgot the contexxt.

In the case of speedballs, I think stopping everything to wait for a TD to approve an undo might be onerous.

I don't know how often you expect it to arise. And I doubt that anyone would ever really know without trialling it.

Would you expect it to arise more frequently in a speedball event than in another? I suppose that misclicks will inevitably be more frequent in an environment where the players are under time pressure. That need not lead to a higher incidence of undo requests, although it is not unreasonable to expect that to be the case.

If there is something unique about speedballs, then by all means have bespoke regulations for those events, which regs might include a ban on undos as "the lesser evil". That need not require those regs to be extended generally.

I don't expect it to be more frequent in speedballs, they're just tournaments where you don't want to have excessive delays by needing a TD for things. So it's just simpler and more time-efficient to prohibit undoes.

It's also not clear that the idea of looking at the player's hand to see if it's "obviously" a misclick is appropriate. In a f2f game, if a player claimed he pulled the wrong card from the bidding box by accident, we wouldn't expect the director to look at his hand to judge it. He either believes the player or not, often based on how close the pulled and intended cards are in the box (you won't get away with saying you meant to pass when you pulled a bid).
