The key here is to avoid 3NT. Assuming West opens 1NT and North overalls 2, East will find it useful to be using lebensohl. His 3NT (if playing FADS) will get West to remove to 4. East might pass, but will probably try 4. Facing a passed partner, West might pass this or could try 4.

Will East open? With 1 or 1? Neither of these is obvious, so it is hard to predict the outcome of this deal. If East opens 1, West responds 1, North bids 2 passed back to West who bids 3. East will now like his hand, but reaching six is far from obvious.

After 2-2 (waiting)-3, East has a tough call. If available, he might try a quantitative 4NT, over which West can just jump to 7.

This is a tough one. The club slam is pretty much on 3-2 clubs, so worthwhile. The likely start is: 2-2-2-3-3NT-4. This makes lots of assumptions. Many pairs will play 3 as a 2nd negative. Even so, this could be the auction; West's 4 would cancel the message of 3 and convert it to natural (how can West have a second negative and only diamonds and remove 3NT)? Now East might make a move with 4 to reach the decent club slam. Like I said--not easy.
