Tests with the new xboard showed no problems.

Thank you for repairing!

I think, an unneeded popup on an invalid move doesn't hurt at all, while a missing popup (when you are expecting one) can cost the game.
Underpromotions are not common, but "virtually never" is not my experience - I wouldn't use an interface that generally autoqueens.

I also have thinking about alternative ways to enter under-promotions. One idea I came up with was to move the Pawn off-board in stead of on the last rank. The X-coordinate could still be used to indicate where you want to promote.

Yet another method would be to use the right mouse button for this. The current use is for the piece drop menu, but this is really deprecated now that we have the holdings displayed, so we could remove it. Right-clicking on the to-square could summon up the promotion popup, while left-clicking would promote to the default piece (usually Queen). Actually this would even be compatible with the piece-drop menu, when the latter would only appear on right-clicking a square when no from-square is selected yet.

The advantage of the second method over the first would be that it is also usable in Shogi, where there are three promotion ranks and the move can only be entered unambiguously when you indicate both coordinates of the to-square (e.g. for a Lance).

Premove will remain a problem in variants where you can only promote to captured pieces, (-variant super and great) as the opponent move might capture something that is not available now. So the premove popup would have to choices that might not be available by the time the move has to be played, making it illegal. (Which is an inherent problem with premoves anyway.) So the choice offered by the promotion popup should depend on if it is fr a premove or a regular move.

Just a thought: Some interfaces permanently show icons for promotion pieces. Whenever a pawn goes in, the actual selected piece is taken. No popup window required.

But probably a lot of work to implement.

Good to know. A premoved stalemate would make me very sad :-)

I have given this some thought, and there seems to be a deep logical conflict between not wanting the promotion dialog to pop up on invalid moves, and have it pop up on a premove. Without a major re-design it does not seem possible to have both.

Weighing all aspects it seems that having premoves autoqueen is the lesser evil. Although perhaps -variant losers could be a problem; from what I understand of that variant it would be more logical to have it autoking, rather than autoqueen.

But in normal games underpromotion virtually never occur, and in the rare case you need one, simply delaying it until it is your turn does not seem too demanding.

So I am inclined to leave things as they are now.

A premoved pawn promotion does now autoqueen, even when "Always queen" is off. Is this new behaviour intended?
