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=D 4H=H 4S=C) or shows singleton 4C=C 4D=D 4H=H
