If this is trolling, it is very well-done and I applaud you. If not, here's the deal:
I went on vacation for a couple weeks and while I was gone, Troy and Bruce stepped up to host great shows and give me a badly-needed break. I was running on fumes, and I felt the show quality had suffered a little bit, and there were a couple topics we had in reserve that I knew I would not be a good fit for. So Bruce did a Bomber Command episode and Troy did Out of the Park. I'm back hosting this week, refreshed thanks to my awesome panelists. The next episode might be delayed a little bit due to some stuff that's going on in our producer's life right now.
By the way, Troy created Three Moves Ahead, so it's not like it's weird when he hosts. He did it for years before stepping down to give me my shot, since he was going into PR and now represents a good many strategy games. He's got a different style than I do, and he and I joke about who is the better host, but the truth is the show is in great hands when I'm not around. And even when neither Troy nor I are around. After 170 episodes, we've all gotten pretty good at this.
