How did the location of berlin enable the soviets to blockade it in an attempt to gain control over entire city

The blockade of Berlin was the closing of the borders that shared the United Kingdom and the United States with the Soviet Union in the occupied German territory. The city of Berlin, located in the middle of the current state (Land) of Brandenburg, was in this Soviet zone (very close to the Polish administration area and to oder-neisse). However, in Berlin there were troops from the other three allied armies, who had arrived there according to the pacts celebrated at the Yalta Conference (1945).

The blockade was imposed by the Soviet Union, and affected mainly the western area of ​​Berlin, then controlled by the forces of the United States, the United Kingdom and France. It was applied in response to the monetary reform imposed by these countries.
