1N is a terrible bid. It PROMISES values... there is NEVER a reason to lie about values over 1
♣... you will always have a 3 card suit to bid, with a very weak hand, unless you have 7+ clubs, in which case pass rates to be the better call
Think of it this way: a bid of a suit at the 1 level carries no assurance of even 1 hcp, while only ostensibly promising 4 cards: any partner will know that a double of 1
♣ will often catch partner with 3=3=3=4 or the like.
However, a bid of 1N carries a positive assurance of significant high card values, not to mention a stopper...one may well lie about a stopper after, say, 1
♦ double: with Kx Jxx 10xxx KQxx, I would probably bid 1N rather than 2
♣.
So when making a bid in a constructive auction, when any bid is likely to at least mildly mislead, choose the call that is the least lie, and if two calls appear to be equally misleading, choose the cheaper one: that gives you more room to recover.
Here, 1N is an enormous lie compared to any suit bid. All suit bids are 'lies' in a mild sense, so I choose 1
♦ as it is the cheapest. It is also the bid least likely to get partner excited, but, to offset that, likely to be the poorest fit: partner will frequently be 4=4=3=2.
