If defended against properly by White, then it puts Black in an unfavorable position. Therefore, it is designed to trap novice players.

gollark: My submission would have been very cool if it were actually entered in this round, which it wasn't due to bee.
gollark: I see.
gollark: Oh, you're keeping the overall balance from the other one?
gollark: Hmm, not the second bit though, I may have to say this.
gollark: I think they're aware of this, yes.
