Turnblocking

I am a newb. and learning gradually. I heard about turnblocking. According to what I have understood. Turnblocking is moving your units to create a wall around an enemy city before any other actions, to stop the enemy from moving. Am I right? or am I missing something? What am I missing?

Turnblocking is when you attack an enemy's unit, preventing them from making their intended moves.
This can be very annoying if someone turnblock a big stack of yours and turn the tide of a war.

Oh! Can we turn block a big enemy stack even with 1 unit?

It is possible to turnblock a large stack with 1 unit, however, the less units you attempt to turnblock it with, the lower is the chance.
Let's say there's a 50 stack and you attempt to turnblock it with 1 unit, it will have about 1% chance of succeeding.

Always send 50% of the stack you're turnblocking

I am wondering, in order for turnblocking to happen do you need to send your units from one place only or can you send it from multiple places???

Also it needs to be before the other player moves their stack, see posts on the turn based system for more info.
