Unless West is in range for 1NT, the auction will begin 1-1
-1
. Now, East will want to raise diamonds. He is too strong for 3
invitational, so will force to game. In new "XYZ" methods, 2
might mean something special. In modern 1990's bridge, East would bid 2
, 4th suit forcing. West now might bid 2
to emphasize "where he lives" and likely (after a diamond raise) East will eventually settle for 3NT.
Board 2: West deals, Both Vulnerable

It is fashionable to open 2NT with decent 19-counts, but I don't see the need to do so with West's hand. As to whether he should open 1 or 1
there is really no consensus amongst experts. Over either minor, East will respond 1
and West rebids 2NT to show 18-19 balanced. East is in slam zone, especially if the opening was 1. If East invites slam, West will cooperate -- he has a maximum and tons of prime cards. Reaching seven is really tricky--there probably aren't many pairs who can reach 7NT being able to count 6 club tricks and 4 diamond tricks.
Board 3, South deals and opens 1, E-W Vulnerable, North bids 1NT (if possible)

1NT Doubled: 1
The bidding will likely begin 1-P-1NT. Now, East has to be brave, but should overcall 2
. West will go crazy, but will he get his side to a slam? If so, let's hope declarer doesn't lose to both black queens.

Presuming a 1 opening, how will East respond? If 2NT is natural and forcing, he can make that call (after which West will bid 3
). East might be able to respond 1NT (only if it is 100% forcing). If system forces East to bid 2-of-a-red-suit, the auction won't develop as well. West will suspect wasted values in East's hand, especially if the response is 2
. One scientific way to reach 7, is if West gets to use Exclusion RKC and East shows the 3 crucial key cards.
