Agree, he'll be back.
But it does sound like RedHotpawn.com (correspondence online chess) would be a much better match for what he's interested in. I usually keep one long game going - sometimes I get some good endgame practice with it that you never get to deeply analyze in blitz.
There's nothing wrong with this site. The correspondence here would be fine for him. It meets the demands of everything he's moaning about namely time and that he wants to use an actual chess board.
The only problem with CC is, you get into a habit of taking on A LOT of games. It becomes unproductive. I'll be deleting this account and starting a fresh and restricting my CC games to a total of 3 because I have 3 chess sets. The only thing that's stopping me is transferring my membership to a new account.
good luck bye
