No, I definitely agree with you, enter the category that you think your beer fits into best. That post yesterday was me venting a bit because I see the same names under categories just with different substyles. I'm not saying they're the same beers, they could be different beers I know. This year I made the 4 different beers to enter, 4 different categories. Maybe if I want to medal, I make 4 different beers but all under the same category but different substyles, and pick the best of the lot. The 4 beers I sent were all worthy of advancing, I wouldn't have sent them otherwise, competition is stiff in this one though.

It is humbling to taste good examples of styles - but dammit, that helles that I made is a helles, and it's a good helles. I'm transported to Marienplatz every time I drink it, so I'll keep making it like I do. I still look forward to getting my scoresheets though.
