1N       2H       2S        2N=natural, opener may bid 3C,3D or 3H to re game try

1N       2H       2S        3C,3D=natural force not necessarily slammish

1N       2H       2S        3H= unbalanced force with long spades. Opener rebids 3S. Res bids               3N to show void (opener relays with 4C to find void 4D=C 4H=D 4S=H) or shows singleton 4C=C 4D=D 4H=H
