Mohan is a
bridgeconvention used to intervene over opponents' 1NT opening. Typically it only applies if the opponents' are using a weak 1NT opening (where 15 points or less is the maximum). Its invention is usually attributed to
John Mohan.
Over 1NT:
Double shows 14+ points, and is often left in for penalty. If it is not, the advancer (partner of doubler) bids as though his partner had opened 1NT. (
Stayman and
Jacoby transfers apply, for example).
2♣ shows both majors, possibly 5-4. If responder does not have a preference, he bids 2♦ to let opener pick.
2♦ is a transfer to hearts,
2♥ is a transfer to spades,
2♠ shows spades and a minor,
2NT shows hearts and a minor,
3 of a minor shows a long minor and is constructive,
