After West's 1, East should force to game. Yes, he has a 4-3-3-3 12-count, but the spots and prime cards make it worth a game force. So, assume 1-2NT (Jacoby 2NT). Depending on the structure, West will make some sort of forward-going move, but East might not cooperate, having already forced to game. This is a tough one--slam is excellent since declarer's heart loser goes on the third diamond. Ironically, if East had the same HCP but a little more shape to the tune of 4=4=2=3, slam would have no play.
Board 2: East deals, Both Vulnerable

After East's 1, I like 2 GF with the West hand, but most would respond 1. That would get raised to 3 and West is in slam zone. He might control-bid 3 and then East will bid 4.  With optimism, eventually RKC will result in the decent heart slam. As to how to play it--that's not part of this feature. :)

Three slams in a row! West opens 1 (in 3rd seat) and now it is a question of methods. East could use Drury, or a mini-splinter (if available). I like to play passed-hand jumps as fit-showing, so 3 would be perfect.  If East bids only 2 (boo--bad evaluation), then West will not try for slam. Over anything else by East, West should show a sign of life and the good slam might be reached.

I hope you had your slam bidding shoes on this month. With 33 HCP, it is easy to reach 6, but what about the grand slam? How about this: 1-1-1NT-2 (artificial GF--see XYZ)-3 to start. Now, East knows his partner is likely 2=3=5=3 (from his 1NT rebid and subsequent 3--not supporting spades.)  Now, if East can learn of the 2 keycards and one king, he can count 13 tricks in diamonds. Voila.
