Tactics: What would you do in these situations?

[Duke John]

For my current project I am researching what drives a player to make certain tactical decisions. So I would like to ask you to look at the following maps and tell me what you would do if you were blue and why.
For this series assume that all troops are equal and that there is no advantage to be gained from the terrain. And don't let your thoughts be limited by the R:TW engine.

Situation 1: Enemy unit positioned to flank:


Situation 2: Enemy forces split equally on flanks.


Situation 3: Enemy has 2 flanking forces and has spread his centre.


In the following situations there is difference in height (dark is low, light is high):

Situation 4: Enemy flanker deployed in valley.


Situation 5: Enemy flanker deployed on hill.


Thanks for any responses
