Whenever a new tournament starts, I have to look at a bunch of games to figure out whether swap is in effect. Monthly cups don't have it, infinity doesn't have it, and championships do. But I'll forget that again before too long, so would it be possible to add something to the screen indicating it?
Even better, we could just always have swap. Certainly it makes sense.
I've just checked, and I guess championships don't have it? (I always wait for one of my opponents to move first, so I can check whether I have the option to swap).
As for me, I think playing on a size-10 board without swap is much harder if you are the second player. Thus, I would also like to have the swap option for all sizes.
Still, it would be very interesting, if someone could find out what the balance of win-loose was for the starting player up till now for havannah size 10 without swap.
