The benefit
of the Criss Cross convention is to differentiate invitational and game
forcing hands with support in opener's bid suit. Without Criss Cross,
hapless players may find themselves going down in a 3 Notrump contract when
responder has 9-11 points with a short suit.
Note: some players reverse the Criss Cross convention
(Method 2), using Criss Cross
to show an opening hand and bid Inverted Minors with invitational values.
