In case it matters, it's all white at IMPs.

Edit: Sorry, 1S should be 2S, obviously.

[Jlall]

2S

[jjbrr]

2S. we have ways of asking how many spades and how strong the hand is, so we can raise on 3 not infrequently.

[skjaeran]

Easy 2♠ raise in any natural system I've played.

[mtvesuvius]

2♠

[Gerben42]

1NT, the hand does not contain a singleton so no raise on 3 cards.
There are good ways to find out a 5-3 fit after this (NMF). I'm surprised that so far it's so unanimous for 2♠, after all I do not know the way ask if it were 3 cards or not after 1m - 1M - 2M in vanilla 2-over-1 (perhaps someone here can tell me).

With regular partners I use a relay, allowing for a 3-card raise with a singleton. But here...

2♠ looks very normal

[jdonn]

2♠, and then partner doesn't have to strain to rebid lousy five card suits after you rebid 1NT, and then you get to rebid 1NT with a singleton in his suit if it seems like the best option, and then your minor suit rebid shows 6+ instead of 5+ which is better for a variety of reasons, and all of a sudden the pieces fit into a very logical and congruous system. The thought makes me happy.

This is one of the classic hands that makes a 3 card raise.

I pity those that feel the need to rebid 1N on this pattern and this dispersion of honors.

[Codo]

This is one of the classic hand that makes a 1 NT rebid.

I pity those that feel the need to rebid 2 spade on this pattern and this lack of ruffing values.

There is a ruffing value.

[Mbodell]

I'd rather play 2/1 with weak nt than strong nt, and this is a hand I'd rather have been able to open 1nt then bid suits. The fact that partner has 5+ points and 4+ spades doesn't change this. If partner has more than minimum strength and/or shape 2-way nmf can figure it out. But 1nt may well be the right place to be.

[marcD]

2♠ guarantees 4 trumps so .. 2♠. I'ill pretend I missorted my hand. Even if we belong in 3NT rightsiding the contact may be critical

[rbforster]

The poll is very insightful - rebidding 1S after (1C-1S) is a nice way to separate 3 card raises from "real" 4 card ones

Yes. That's why you should play transfer responses to 1♣.

[the hog]

Easy 2S bid.

[Fluffy]

What about rebidding what you have agreed with partner?, for most people I know this is a 1NT no brainer rebid.

It's a cultural thing. In some areas/environments this is an just as obvious 1NT rebid as it is a 2♠ rebid other places. For me, 2♠ is clear.

That's always a good thought : wins the post mortem Still even though the no brainer systemic bid is 1NT I think the right bid seems to be 2♠. Will take the blame if the experiment goes wrong but system is supposed to help no to get in the way

Ditto. The ♠ are just barely good enough
