How are you handling stealth in combat?

This shouldn't require that much in the way of judgement calls. TFT is played on a tactical map where everyone's location and orientation is defined at all times. I'd say there are only three situations that can arise, only one of which might call for a die roll:

1) Target is totally unobstructed and can be seen through a front facing: no way on earth you can 'hide'
2) Target is totally obstructed or only reachable through a side or rear hex side: no way on earth you can be seen (at least in that moment)
3) Target can be observed through a front hex side but is partially obstructed (by a barrier, natural shadow, whatever). This case is not covered in the rules but could be reasonably modeled by saying if you don't move and succeed at a stealth check you are functionally invisible until you move or are observed from some different orientation.
