I was wondering if it was possible to somehow automatically set up the conditional move feature for multiple games at once, particularly the opening. I play the same opening every time and follow most opening lines to the more popular openings, and I just thought if it were possible it would save a lot of time. My first thought was that it might lead more people to cheat by setting all their lines to the popular openings, but people could do that now anyway so I don't think setting conditional moves changes the odds that much anyway. I think this feature should be looked into more if it is not already.

Yes. 

   Problematic if your opponent moves quickly.

I mean set the moves before the game even starts for all future games. If so, how?

Create a "seek" that starts the game from whatever postion you wish to play.

Since opening books and databases are allowed in turn based, I can see the value in being able to have a library of conditional move trees starting in the opening position that you can simply apply to a game (or games) as desired.

That being said, I think you'd be robbing yourself of the practice that comes with playing through the key lines of the opening by hand if you used it to simply copy out the best lines from opening books and databases without bothering to understand the key ideas behind them or to actually learn the openings.

Now, how you are finding, and why you would want, people that play the same moves each time around is beyond my understanding, but that would be a way to make it happen.

Books are allowed?

No wonder I see so many inflated ratings among the partners I play against.

1. I play random games against random people.
2. I play different openings with the same lines, eg. for e4 e5 I play the Italian, for e4 c5 I play the Alapin, etc.
3. Bobby Fischer made it a point to not play d4, he did so like only once or twice. Playing similar openings means understanding the position deeper. Althought I understand the two trains of thought.

Also theGrobe, I'm pretty sure books and other thrid party advice aren't allowed on turn based, lol.

Third party advice, no -- that includes engines and endgame tablebases.  Books and opening databases are allowed in turn based, but not live.

Bobby Fischer had mental problems.  Undiagnosed Aspereger's and some other untreated issues.

Not a good road map for chess or life, actually.  To accomplish one's goals and yet be so profoundly unhappy and hurtful is not anything I would wish upon a people who are decent folk.
