Wow, such a quick reply!

No, it certainly isn't obvious, so I don't feel so bad. I guess that score only means something once the tourney is complete.

Kind of like the tiebreaker system for NFL football playoff brackets.. having to do with strength of schedule and records against common opponents ...

I'm using Arena to play a round-robin between 3 engines (Houdini,Critter,Stockfish). The tournament table headers look like this:

Engine Score Ho Cr St S-B

Can anyone please tell me what "S-B" means? I'm sure it's ridiculously obvious, but I'm missing the meaning.

Thanks!
