Nothingness:
Preference would be for either Open Fast or Small Fast. Not too bothered about time limit, but probably 5 - 7 days good for most.

I am currently stuck in a tournament where my opponent has burned thru more than 80 vacation days and hasn't moved since March 3rd!! I absolutely, positively will not play in any tournament that doesn't use Fischer's clock.

Thad: maybe limited vacation in tourney? Anyway, I'm only in when it's small fast...

Chaos: There is no way to limit how much vacation a player can use. It's all or nothing. Too bad Fencer can't (or won't) program BK so that the game/tournament creator can limit how many vacation days a player can use in any one game/tournament. That's one of the things that keeps this site from being good.

Thad: If you use time per move, does the option 'No days off'' not prevent vacation days from being used?

If using Fischer (time per game), then a 5 day move limit without vacation can still be set up, as the bonus and limit options can also be set to 5 days!

SL-Mark: Yes it does, but if no one can use any vacation days at all then a lot of players won't play in those tournaments.

So to ask an open question...
How long should an Espionage game take to complete at the longest? A month? More?

Thad: Answering the question how long should an espionage game take:

Small Fast is generally done in under 60 moves. Usually well under (95% of the time at least one of the players knows who will win within 30 moves), though about 2% of my games go 100 moves. 113 moves was the longest of mine.

Open Fast is generally done in under 70 moves. I don't think I've ever had a game go 100 moves. Open Fast games often remain in doubt a bit longer but generally resolve very quickly because of the extra moves.

The games with obstacles can go much longer . . . I think I once heard of a 300+ move game.

I am generally a patient player, so my wins tend a bit to the long side.
