Beginner: Mobility

Mobility is a key consideration for Stratego. When creating setups, one should consider how the bomb placement as well as the location of other key pieces will affect mobility. In most situations, in the mid-game, one will want to have the ability to easily move between one side and the other on your end of the board. If bombs block off this mobility, it can be quite limiting. Some key considerations for mobility are:

Bomb placement
One should consider mobility in the original placement of bombs. blocking access to one side can prove problematic in the mid-end game, as you may not be able to access a side of the board, which can give the opponent an advantage. Also, putting a lone bomb in the top two rows means that you will always have to move around it, which also decreases mobility.

Miner placement
It is advisable to put a couple of miners in the 2nd or 3rd row on each side. Otherwise, if you need to break a bomb enclosure, you will have to move a lot of unmoved pieces just to get your miner out.
