Muiderberg - Muiderbergh - The Dutch Two Bids - The Lucas Two Bids - The origin of the Muiderberg or Muiderbergh Two Bids, which is sometimes spelled differently, and which is sometimes referred to as The Dutch Twos and the Lucas Two Bids, began in the village of Muiderbergh, The Netherlands, which lies near Amsterdam. The concept was devised by Mr. Onno Janssens and Mr. Willem Beogem, who both lived in this village, and is based on Weak Two openings.

The origin of the Lucas Two Bids is unknown and the original definition was that it represented a 5-card suit either in Diamonds, Hearts, or Spades with a second 4-card side suit in the other Major if the opening Two Bid is in either of the Major suits. The high card point range was between 6 and 10 high card points. In general, the responses follow the same pattern as the Muiderbergh Two Bids and are therefore included as being based on an identical concept.

Note: The Dutch Twos approach of bidding on the two level bid and being defined as showing a 5-card plus Major suit with a 4-card plus Minor suit and a range between 6-10 points is also known in the United Kingdom as The Woo Twos or The Woo Two Bids. This designation is for Mr. Alan Woo, who is a member of the Young Chelsea Bridge Club of London, England. Source and Source. The Lucas Two Bids approach, as described, is also not identical as the Dutch Two Bids, although they are very similar and contain only slight differences.
