= Mauritian Twos = These are weak hands &mdash; 5-10 HCP or a bad 11 HCP (W200#24N) &mdash; 5+ cards in one suit, 4+ cards in another suit, with 8 losers or fewer.
 * They are for opening bids, not for overcalls or responses.
 * Prefer to open at the 1-level if you can &mdash; e.g. with 10 HCP and two 5-card suits, giving you two length points.
 * If you have 6 cards in a major, prefer to open a Weak Two.
 * If you have 7 cards in a suit, prefer to open with a 3-level pre-empt, unless you have 4+ cards and a stopper in another suit.'.     (F200#2N)
 * The majority of your HCP should be in your two suits, but don't give up if they aren't. (C201#32N).
 * The three bids that comprise  Mauritian Twos  are:
 *  2HS undefined: 9+ cards in two suits, of which hearts is a 4-5 card suit.
 *  2SS undefined: 9+ cards in two suits, of which spades is a 4-5 card suit. The other suit is a minor.
 *  2NT: At least 5-4 in the minors.    (F200#1S)


 * With a 0-4-5-4 shape in SS undefined-HS undefined--, bid 2HS undefined in preference to 2NT. (C201#27S)

Critical Hands for Mauritian Twos

 * T20#6E : 2NT is better than 2HS undefined.
 * T20#9E : 2SS undefined is better than 2HS undefined.
 * W200#31W: 3 is the least worst contract.
 * F200#3W : 2SS undefined is fine, but it cannot be found after a 2HS undefined opening.
 * F200#33N : 25 HCP and everything stopped but 3NT goes down two.
