NS vulnerable. East dealer. Opponents don't interfere.

This depends slightly on your style. I suspect most people open 1♣, then some will bypass the diamonds, some will bid them.

We would bid:

1♣-1♦-1♥-1♠(4SF, F1 for us)-3♣-3N

East opens 1NT. I see from your profile that you use SAYC with a 15-17 no trump. The bidding would go 1NT - 2♣ - 2♥ - 3NT. If you open 1♣ and partner bids 1♠, you are telling a lie if you rebid 1NT (12-14) or 2NT (18-19) or 2♥(17+)

Before opening you should always prepare a suitable rebid (or pass) whatever partner (or the opponents for that matter) throw at you. I'm not 100% keen on opening 1NT with 5-4-2-2 shape, though this hand is an exception to the rule. It's not a great hand generally, but it just about makes a 1NT opening on the K&R evaluator coming out at 15.00 exactly. (It might have 16 HCPs but it comes out less due to the awkward doubletons.)

I think most people today would just bid:

1NT
2♣ 2♥
3NT P

More traditional bidding is still going to lead you to the same place.
Slam seeking in NT or clubs (not that there's any great reason) is going to find two missing Aces and stop in NT.

Same for me.

Than you for your answers.
What happened: 1Club - 1Diamond - 1Heart - 1Spade - 1NT - all Pass.
(My partner doesn't play SAYC, but a system that says: with more 4--Card suits, the lowest first.)

Was 1♠ natural or 4th suit ?

1N is a 12 count in my book, not a 16 count unless you play 1♠ 4SF FG.

Sir playing Standard we would bid 1C-1D-1H-1S-3NT.We are not interested in finding a 3 card heart support nor do we wish to play in 5C.as there are far too many losers for that .Playing Precision we bid 1C(16 +any)=1NT(8/13 hip balanced and no five card suit)-2C-2H(4 card Spade and 8/10 HCP)-3C-3D=3NT. 3NT albeit from the wrong hand.

+1 for The_Badger's post.

1NT - 2C - 2H - 3NT

only question is opening bid the hand is not good enough to open 1 club and reverse to 2 hearts, and while some people have issues about opening 1nt with 2 doubletons,with honors in both of them this is a minor deviation and I think a smaller lie than opening 1c (you will never recover to tell partnew your hand strength)

[Caitlynne]

Playing a strong 1NT, 5 card major system, I would open the East hand 1NT in order to avoid a rebid problem. If I open 1C and partner responds 1S, I am stuck. I am too big for 1NT (12 to 14 HCP) since I have 16 HCP. I am not strong enough to reverse into 2H either since I don't know where the hand is going so I can't take such control.

(Reversing with fewer than 17 HCP is uncommon - but the true test of a reverse is whether you can handle all rebids by partner - and you cannot with this hand - 2S would be embarrassing since you don't have enough to bid 2NT if partner has scraped up a 1S response on an ugly 6 HCP).

So I avoid the headache by making an off-shape 1NT opening bid. After that, West will/should explore for a major and, when no major suit fit is found, should settle for 3NT.

1N - 2C, 2H - 3N, Pass seems like a typical auction.

In general, playing 15-17 NTs, with four hearts, a five-card minor, 2/2 in the other suits, and 15-16, you should always consider opening 1NT (with 17, you can reverse, and with spades, you can always rebid 1S). This hand in particular is well-suited to a 1NT opener, which, as earlier posters have mentioned, saves you a lot of difficulty on ensuing rounds of bidding.

All the blame to East who has a clear 2NT bid at his 3rd turn (shows 16-17 HCP); with more rebid 3NT, with less 1NT. West was right to pass 1NT.

It's surprising how often players are lost when the book bids end.

As others said, it's probably best to open 1NT to avoid a difficult rebid over a 1!s response.
