None of you understood me:
I'm not against jumping in Go – I'm against bypassing guards on portals or other objects when it's possible to do so. That is, if there's a path on the ground that can be jumped over – go ahead, but if it's a portal, and the player defeats the first monster, and the second one is positioned in a way that it doesn't need to be attacked – then, in this case, I think the player should be required to defeat it.

It is FORBIDDEN to use the map bug "shifted guard," i.e., to pass into an adjacent zone or pick up an artifact without defeating the corresponding guard.
