Battle position changes

From Yu-Gi-Oh!

A Monster Card’s battle position can be changed in one of two ways:

A "manual" change can only be performed during your Main Phase 1 or 2. There are 3 exceptions that will prevent you from changing a monster’s battle position:

Please note that:

Example: You activate "Book of Moon" and flip a monster into face-down Defense Position. Then you can Flip Summon it that same turn, as long as none of the 3 exceptions exist.
Example: "Cyber Jar" Summons a monster on the opponent’s side of the field, and the turn player uses "Change of Heart" to take control of it, then Flip Summons it that same turn. This is a legal play (as long as none of the 3 exceptions exist).
