Torre attack vs London system

Neither are just playing a structure and pattern. If you want to play them well you need to know what to do against what your oponent is doing. If you have the London then you have a choice of Jobava and regular London. You also have a choice of Trompovsky or Torre. They all have slightly different ideas. Finally in the QG you can still get your dsb out if you play different move orders. Have fun with them.
