Here’s a scenario: You’re a sheriff, and Night 2 you get an unseen check on someone. Conventional wisdom seems to be to announce it in chat immediately the next day. This seems like the common play, and I’ve seen very good players like Dadmos do this consistently.
But, should you? What do you actually gain? Since the check was Night 2, you know they aren’t the Mastermind. Assuming the MM successfully converted Night 1, if you execute him on Day 3, the MM can convert someone else that night. If you let him live, you know who 1 out of 3 of the unseen are. If you execute him, the MM converts and now you know who 0 out of 3 of the unseen are. Not only this but knowing someone is unseen you can see who they are accusing and who they are defending. Who they vote up quickly and who they drag their heels on. You can’t get any info like this if they are dead.
You don’t slow down killing unless the MM is alone, which could happen if he failed to convert a lot. But statistically, it’s unlikely and so not a good play to bank on.
Then there’s the fact that announcing it makes you a huge target for conversion or killing. If you wait until the MM is found and killed, you can ensure you won’t be converted, and that unseen will have to operate with just an assassin.
One concern with leaving them alive is the increased voting power, but that isn’t really a problem early on, and if it’s getting to the point where the votes are going to start to get tight, you can just announce your findings and kill him then.
Another is the benefit of the abilities the third unseen give… but again, unless you get the MM they’re just going to convert someone else and you’ll have to deal with that anyway. Plus, the deeper into the game it is, the more information the MM will have on who to convert.
Is there anything I’m missing here on why this is a bad strategy?
