Here are the fields you'll see for a tournament:
Maximum Section Size
Play Each Side
Active and Completed tournaments also show the details of the rounds of the tournament (so far). Each round is listed separately. In sections-style tournaments, within each round the sections are shown listing which players are in the section. You can see the individual games in the section by clicking the "[Show Games for Section]" link. That shows a grid with the player names in columns across and rows down the left: The intersection of a column and row shows the result of the game between those two players in this round. The final column of each row shows the standing for that row's player.
