Muiderberg - Muiderbergh Two Bids
The following is an explanation of the Muiderberg - Muiderbergh Two Bids in the native language, which is sometimes spelled differently and which is sometimes referred to as The Dutch Twos and the Lucas Two Bids, which was devised 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.

Muiderberg - terug naar Biedermeijer rood
De Muiderberg die genoemd is naar de woonplaats van een van de bedenkers.
Openingen van 2 
en 2 
waarmee een vijfkaart in de geopende kleur wordt aangegeven en een vierkaart in een lage kleur.
Met ongeveer 7 -11 punten.
Het is belangrijk dat de puntenkracht zich in de lange kleuren bevindt, met name in de hoge kleur.
Door de toepassing van Muiderberg vervalt de sterke 2 en 2 openingen.

Be aware whether or not the feature is alertable or not and whether an announcement should or must be made. Check with the governing body and/or the bridge district and/or the bridge unit prior to the game to establish the guidelines applied. Please include the particular feature on your convention card in order that your opponents are also aware of this feature during the bidding process, since this information must be made known to them according to the Laws of Duplicate Contract Bridge.
