The most important question is where to see TCR ==

2D&3D are just to show 5-5+ H&D but the cue bid shows a void/singleton in clubs and good pts. However, you two may be 4H~7H so good players will adopt rkcb. 6H is a beginner bid. By the way, spade is the most reasonable lead.

It's puppet stayman. 3S= 4+S,4-H

It's easy for a beginner even a novice to play, please. 11-12 tricks.

2D-PASS-4D-PASS-5D-PASS

First to say, north has no 3D to show good pts so north is a beginner. But after north bid 3D south must see it as good hand to bid 3NT with a club stopper. If north does not think his hearts and diamonds are strong enough to get winners for 3NT he would bid 4S for safe contract.

Your partner must have general 16pts or weak hand with long hearts so you two may be weak at clubs. You must bid 4NT to ask for keycards to check how strong your partner is. If he is weak you can stop at 5H and find a slam if he is strong or he has 2+ keycards.

DA is your first trick so you need 9 more tricks. First, go CQ to try to take 2tricks on C. And then use your spades to overtake D&H. With generally distribution, trumps can all be used for 7tricks. If W has CK to overtake and then break trump, you will lose one trick when doing D&H. So the only way is to go 3rd of clubs before doing D&H for one more trick. It is still dangerous if W has CK. But the original cause is the idt south, 1S&4S with only 3 cards.

It's no solution.
