Paper on connection games

A paper on connectio ngames was just posted on arxiv. It shows havannah and twixt to be pspace complete just as hex.

The result is very interesting in my opinion and the authors are players here. Congratulations on the good work guys. I apologise if it has already been posted.

Sorry, I just saw the paper was from 13, (only just posted on arxiv), so it was likely already posted.

Nevermind, an old paper just me being stupid and distrought :)

And at least 2 of the 3 authors' names are familiar ;)

Well it was new to me, thanks!
