the end of the database tree should contain the fruit
I don't understand why after twenty moves the database abruptly stops. I understand that it stops, but it should list all available games of that branch. This would make deep analysis of a position more interesting! I have certain positions where I still have twenty games at the end which I played. To find those games back in my past game history is not that easy! could GK do something about this 'flaw'?

Agreed with wuzzie!

This might already be somewhere down the to-do list, actually... I'm guessing they're too busy preparing new features & ironing their kinks out, while leaving the old the old.

wuzzie's motion to extend the depth in the GameKnot DB
I second the second

The max depth of the GameKnot DB has already been extended to 30 moves (from 20 before). I think there are only about a dozen or two cases where it actually hits the limit (out of 1,184,881 total games in the DB at the moment).

Isn't it 40 actually?

There are loops in the DB that keep some lines going without any apparent end. I'm assuming these are games that should have ended from the position repeat rule. I quit search one line at about move 100.

This is no joke. It's real and in the database. The problem should be fixed.

Yes, heinzkat, you are correct, it's 40 moves. I should've confirmed the number in the actual script before, instead of relying on my memory.  

lighttotheright, it's not something that we can "fix" in the DB. The "problem" isn't with the database -- the DB simply contains positions (i.e. FENs) and all available moves that were made in/from that position. If you keep clicking on the same sequence of moves that lead back to the same position, you'll just keep going in circles (the DB will happily keep reporting the same position and the same set of moves available each time, since they did indeed happen). You simply need to pick a different move at some point that leads out of the infinite cycle. Or if there isn't one available, that means all the games involved ended either in a draw (threefold rep.) or one of the players resigned during the repeated moves. It's just like a bicycle -- if you keep making a left turn all the time, you'll be going in circles too, but it doesn't mean the bike is broken.

By the way
I just checked... and the "World" database still doesn't give output after the 20th move. Are there similar updates planned for that part of the database too?
