Please don't misunderstand my post as being "standard mechanics".
When in doubt and if your partner has the better angle, it's best to get the information before the call. When done, BU merely points at PU and asks, "did he have the base", or "did YOU see a tag."
Changing a call is not an everyday event, is not a standard mechanic, and shouldn't be used as a crutch for good mechanics and solid judgment. Still, if blocked out due to the circumstances of the play, and if your partner likely has the needed information to help make an accurate call, then it's better to get the call right than to live with an obviously blown call.
Just my opinion,
Freix
