How to navigate Arena

Heres a link.
specifically, how do i organize engine tournements/matchs.
I figured out how to load a new engine already.

Click on ENGINES/TOURNAMENTS/
A window will pop up
Click NEW, it will prompt you for a name for the tournament.
Add all the engines you wnt to participte to the left hand window.
Select your time control. (LEVEL)
Select number of rounds, for some strange reason mine defaults to 10, change it to 2 for a RR where each engine plays both Black and White .
Clck Start, and off you go...

Thanks. I tried that and the computer never moved. It just kept thinking forever. i'll try agian; maybe i missed something.

OK, I think the problem is you engines are not using the opening book.
Click Engines, and on the details tab tick the box for use Arena Mainbook for each of the engines.

Thanks. I don't know why, but when I tried it again, it worked. thanks. Do you know what ponder and gauntelet and carousel are?

Gauntlet: The top engine plays against all other enges only. the lower dont play against each other.
Carousel is just a way of determining the draw.
I think ponder allows the engine to think during the opponent move. I'm not sure if this is available in engine vs engine, I think the the active engine gets all the resources.

Thanks. I'm going to organize another engine tournement.
do you know of a free version of fritz I could download? maybe an old one that has run out of copyright time?

I think Fritz 5.something is now free.
But I would rather use SCID, I think it has more bells and whistles.

SCID is a free interface. (a bit like Arena)
SCID (For me) is better for database functions, arena is better for playing.

Basically, How do I navigate the arena GUI?
