Doesn't Like Don't
The following was posted on rec.games.bridge by Gerben Dirksen:
The problem with DONT compared to Brozel is the 2 and the 2 bids. They come up more often but this makes a mess of things.
For example suppose partner bids 2, showing Clubs and a higher suit. Fans of DONT will tell you this is a great bid since you got them out of 1NT and you show Clubs, so you may stop in 2. Let's see what happens in practice.
(1NT) 2 (2)
Now if you have Club support, that's great! If not, you will never ever ever find your fit if you have one. Partner might have Hearts. Or Spades or Diamonds. Oh well. Let's go one better: Third seat passes. That'll make things easier, right?
WRONG!
Suppose you have a quite normal distribution: 4=2=4=3. You are now in a 4 - 3 fit, possibly. Should you pass? Probably. Only to find out that the rest of the field played in a 4 - 4 fit in either pointed suit. But if you bid on, you will play 3 in the same 4 - 3 fit as before, now doubled as it turned out partner had Hearts.
2 has this same problem but less extreme as there are two suits to choose from.
My suggestion is to stick to what you have or if you want something new but similar, try Lionel.
