Mainstream 2/1. Matchpoints.

I assume you play constructive raises. West is way too good for 2S, so 100% West for me.

It's not clear what West should bid at his 2nd turn but clearly it isn't 2♠. Either 2N or 3♠n would have got the job done.

As for East, it depends on partnership agreement as to the requirements for an immediate 2♠. I think it wrong, in an atb, to look at East's 1N and assume that it was the right bid.....if we do that, then the problem is silly, since if E might the right bid, how can East be at fault? Surely no-one in their right mind would suggest that East show an invitational spade raise over 2♠?

If they were playing constructive raises then 100% W. If they weren't then both made equally bad calls, but W could and should have saved E, so W bears the fault, but the criticism is equal.

Indeed, if they played constructive raises, I have to wonder why this is posted, other than to 'win' a meaningless argument.

I don't really know what "Mainstream 2/1" is, but I'm glad I don't play it.

Obviously west for gross underbidding. This is basic stuff from the first month of lessons.

Even if east bids 2♠, there is no reason to think that this west will not pass that out.

This question would be better placed in beginner/novice.

If we define a constructive raise as one which would be accepting invites, but isn't an invite itself, then this flat 7-count is a constructive raise; and after a simple constructive 2S raise. Opener should simply bid 4. However, West seems to have focused on that aspect when he rebid only 2S ---and ignored all the 9 or ten counts without 3-card spade support Responder might have and would pass 2S when game is cold. So, yes, West bears the full charge (or credit if the opponents were fixed) for the contract of 2S.

What's wrong with rebidding 3♠? That should solve it easy. Well, 1S-2S would too.
