It is easy to forget about

I won't bother working out the notation but I have seen that sometimes it pays to do a sneak attack up the wings while your opponent postures in the centre. Also, if you can get your commander tank, or whatever it is called, into the squares in the centre of the board it is not only safe but is a concealed threat.

Are there any given tank battle openings/tactics I am in the tournament and I haven't noticed any popular patters of play and games seem to either be open - tons of exchanges, or closed - piling up pieces waiting for the other to take first.
