Muiderberg in the limelight

The Muiderberg two opening is simple and effective.
Here's an refresher on its succeses.

Three years ago I introduced the Muiderberg two opening in BRIDGE. I've worked hard since then. My booklet on the opening sold out in less than a year. We need a reprint.

But more importantly, the bridge public - from Premier League to 'ordinary' club players have picked up the convention, incorporated into their own bidding methods and not dropped it. Muiderberg, and variations of it, have become a craze.

Why is Muiderberg so popular? I'll look at this this from the twin viewpoints of game experience and technique. This will explain the specific characterics of the opening.

Simple and efficient

Much of what has emerged from modern bidding thery has been complicated and difficult to understand. But you can learn Muiderberg in the blink of an eye.


2H:5-10 points, exactly five hearts and four cards or more in a minor

2S:5-10 points, exactly five spades and four cards or more in a minor

It is essential with a major fit and few points to bid up to a high level quickly. Your objectives are two-fold. You will reach games that others won't have imagined, and you will very much upset your opponents bidding. A hand from the Spring Foursomes, a tough English tournament, illustrates this point splendidly

East, Arnould Oltmans, knew that from brother Erik's 2S bid that he had a 4 card suit. (Otherwise he would have made a support redouble showing 3 spades). So he jumped to game.

South led the D6, his singleton. The defence have two trump tricks and the CA. But when North got in a trick later with SA, although he can give south a ruff, he cannot play clubs as well. A heart return gave declarer no problems, and that was +620 to East-West.
