Townhall placement in Clash of Clans

Why do some profesional Clash of Clans players place their Townhall way beyond their defenses and outside their walls, from where it can be easily destroyed?

Won't the attacking player easily get a two star even without much strategy by decimating the Townhall and getting a 50% destruction afterwards?

Solution 1:

While the Townhall is an important structure and gives a star if destroyed, in many of the top clans, wars come down to how many 3 stars your clan can get. Therefore most top players build anti-three-star bases and forgo trying to protect their townhall allowing for a basically free 2 star raid on their base in hopes that they won't get 3 starred.

At townhall 11+, the townhall itself becomes a fairly decent defense in its own right with the tesla. Treating it as a defense instead of a VIP to protect allows for different base designs that take advantage of its hard-hitting multi-target Tesla.
