Well if the shorter move has variations which does not require clicking another square, then that will not work. For example the shorter move could have promotion options ... Not the case for chu-shogi lion but still may happen in other cases.

We can use a click on the same square to signal the referee to send us a single move i.e the shorter one instead of a move list. But I still like the idea of popups since there is no other way to offer option for promotions pieces. So we need another signal if we reserve clicking on any square again to send a move. Plus the popup could be a faster way of making a move in some cases. So we can still have that I guess.

Btw I changed it to "moves 2 e2e3 e2e4" instead of using teh same command "move" to signal popups.

Edit
I don't think you can get away without using the referee in 'alien' mode. There are just too many exceptions to handle them all in a uniform manner. For example promotions. Shogi for instance has each piece promote to a different piece, that would be too much to handle for the GUI. I think whenever a 'human is about to play, the referee has to be there. Because of that I am going to add referee in FICS play too. Referee is not required in engine-engine or other cases because they will make moves by themselves.
