Newest member, Andreas Diller, comes from a family of chess-players. He showed me a German web-site, schach.de, on which he has a membership and a long history of tournament play ... alongside other Dillers: his aunt and his father! He has also played in conventional tournaments in Germany, gaining "podium-places" in regional championships.
He shares with me two favourite openings, French Defense (1.e4 e6 2.d4 d5) and King's Gambit (1.e4 e5 2.f4), and plays the first alarmingly well as white and as black. He uses his rooks very well, I thought, as in three games of our four so far, I have been confronted with doubled rooks. In two of those games, the doubled rooks were on not-so-likely files, "a" & "c", and they had great immediate or latent power.
