I've read and seen that at the last round of a swiss teams event if the first team is ahead of the second one by so many VP's that it is impossible to catch up, then the first team is pitched against the last one and the second can play the third, which is a bit fairer. Or is it? The idea behind this is that the first team might play badly 'on purpose' and let the second team win by much thus taking all hope from the third placed team. This seems to be fairer for Nº 2, too as they could lose to a 'serious' Nº 1 and not have as much opportunity as Nº 3. What's correct?
