Jacoby 2NT
1H P 2NT is Jacoby- means 4+ support and 13+ points. Confirms game and investigates slam interest. Do not use after interference
Jane, playing 4 card majors here!
With a strong hand, 6 or less loser, rebid by opener of 3H will show 16+ points and 5 card suit. A bid of a new suit at the 4 level shows a good 5 card suit of the side. Bid at the 3 level of another suit promises a singleton or void. 3NT means only 4 cards in the suit and 15+ . 4H with minimum hand, up to 15 points, and 7 or more losers

Only difference is that 3M not only hasto be strong but also a 5 card suit. So, with Jane, what happens if opener has 19 points but only 4Ss: just has to bid 3NT
