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

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 1bridge card suit or 1bridge card suit there is really no consensus amongst experts. Over either minor, East will respond 1bridge card suit

 and West rebids 2NT to show 18-19 balanced. East is in slam zone, especially if the opening was 1bridge card suit. 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.

The bidding will likely begin 1bridge card suit-P-1NT. Now, East has to be brave, but should overcall 2bridge card suit. 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 1bridge card suit opening, how will East respond? If 2NT is natural and forcing, he can make that call (after which West will bid 3bridge card suit). 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 2bridge card suit. One scientific way to reach 7, is if West gets to use Exclusion RKC and East shows the 3 crucial key cards.
