Multi Defense - Defense against 1NT and artificial club opening

An email I got from Dominique from the Netherlands.

In the Netherlands we play something like Suction but it's a bit different. I also created a variant to play against 1Club [alerted] which happens a lot due to the Dutch Doubleton opening.

The name in the Netherlands is MultiDefense

The last 2 are advised to be played with tolerance for the 3 playing level.

If opponents double the bid: Redouble means bid your colour, pass shows a 5 card suit in that colour.

Versus the 1Club [alerted] opening I moved some of the bids from the otherwise natural sequence to a more effective position.
