Auctions, either neutral or disturbed, become fit if we agree or unilaterally set a suit, and remain so for the rest of the auction.
The bid that agrees or sets a suit is a fit bid. It agrees the most recently mentioned suit in which it is possible to have a fit – usually the last shown suit. It also conveys a specific message within that newly created fit auction e.g. limit, splinter, controls and so on.
Fit bidding is the most structured and conventional of the Chilli auction types.

Again fit. 2NT is a fit bid in this sequence.
