I am trying to set up a script to practice my bidding using Brozel to interfere with a strong 1NT opening by the opposition.

I have it set up on the bidding table to have west as the dealer and to randomly rotate the dealer by 180 degrees. My script is below. But when I run it through the dealer program west's hands are not always balanced and north sometimes does get a balanced 4333 shape.

What am I missing?

// West (opposition and dealer) has a strong 1NT opening bid.
1NT_W = shape(west, any 4333 + any 4423 + any 5332)
and hcp(west)>=15
and hcp(west)<=17

// Set the conditions for a Brozel
OC_2C = shape(north, x5x5 + x4x5 + x5x4)
OC_2D = shape(north, x55x + x45x + x54x)
OC_2H = shape(north, 55xx + 54xx + 45xx)
OC_2S = shape(north, 5x5x + 4x5x + 5x4x + 5xx5 + 4xx5 + 5xx4)
OC_2N = shape(north, xx55 + xx45 + xx54)
OC_DB = shape(north, any 6xxx + any 7xxx + any 8xxx)

brozel_OC = OC_2C or OC_2D or OC_2H or OC_2S or OC_2N or OC_DB
brozel = 1NT_W and brozel_OC

condition brozel

Perhaps a silly question, but are you missing the meaning of the 180 degree rotation? This means West will only have the 1NT hand and North two suited half the time - it will be East and South the other half.

I have no idea what is wrong with the script but I see the same behaviour.

If you change your condition line to:

condition 1NT_W and brozel_OC

then it will work as you expect. I do not understand why this is different.
