Chilli: simple universal bridge bidding: neutral four of a minor

A neutral bid of 4 or 4 has similar possibilities to that of its major cousins 3 and 3. They are:

if the bid is a raise or a jump, it is a fit bid
if the bid cannot be natural, it is an impossible suit bid
otherwise it is a forcing suit-setter.

As for three of a major, a suit-setter will show a (semi-) solid suit when used prematurely. See neutral high bids for the meaning of the impossible suit bid above 3NT.
