I have judged 2nd round 4 out of the last 5 years. It has always been queued judging. We also used queued judging in Seattle for the first round the last few years too. It definitely helps speed things up. You essentially have a steward for the entire table. He pulls the first beer (normally in lightest->heaviest order) and hands it to the first pair, then as a pair finishes their beer, they get the next one from the steward. Faster pairs end up doing more beers. Slower pairs do fewer beers. The whole table finishes at about the same time, so it's right on to Mini-BOS.
Chatter I've been hearing is that they have more ranked judges this year than slots, so they will give priority to higher ranked judges first. In all honesty, if you are provisional or rank pending, chances are you will not get a slot, as they will fill with highest ranks first. The place is swimming with BJCP judges, and I suspect there will even be some Recognized judges who won't get to judge.
That said, you can volunteer to steward. It's a valuable learning experience, and frankly you get to sample more beers, and listen to what all those experienced judges are saying about the beers (without having to taste the less than stellar ones -- yes, I've seen teens and low 20's in the second round - things happen). It's not often you get as many National, Master, and Grand Master judges in the same place, so listening to what they say (and tasting the leftover beers as you take the bottles away) is in some ways more fertile ground for learning. Remember, you'll get out of it what you put into it. The old adage about "if life gives you lemons, make lemonade" holds true here. Folks can either b**** because they don't get to judge, or they can turn it into something valuable. You might even get to steward for someone like Gordon Strong, Phil Farrell, Al Boyce, or Ted Hausotter. I guarantee you'll pick up some nugget of info from them.
I really wish I could go this year, but my daughter's graduation is a bit higher priority for me this year. See you in San Diego in 2015, though-
