15-17? Gosh, what do you do with 18?

You can upgrade your 1NT openers all you like but a r/w 1NT overcall is not exactly the same thing.

I double then bid 1N with 18-20.

Not so much over a nebulous club, but I upgrade my 1N overcalls frequently over suit openers where say my KJx in opener's suit becomes worth more than 4 points (and much better than Axx).

It's also not like my diamond suit is so good I want partner to lead one from say Jxx against a suit contract.

Unless you can't bid 1NT because the auction has gone, say, (1♦)-X-(2♦)-p-(p).

And yes, of course you can upgrade positional values in a suit bid on your right. But your range, after upgrades, can and should be a different one than for your opening 1NT.

It is, even I don't overcall a 12-14 NT in 2nd seat But seriously overcalling 1N on a 15 count is pretty common over here, I'd suggest 15-17 or 15-18 is normal particularly in club bridge.

Light 1nt overcalls work fine in a field where nobody knows that double is penalty.

Of course I bid 2N. But even if this were non-forcing, I wouldn't worry about it. This may well be the hand where we can't make 3N with 25-26 balanced - give partner any 10-11 count where diamonds aren't running, where we only have one club stop, and where RHO has a 5-card club suit.

Hi,

it is either 2NT or 3NT, at IMPs I go with 3NT.

With kind regards
