As usual, when you preempt and turn out to have a fit (or double fit) you do well. But what about this auction implies a fit? Can't partner have a bunch of black cards?

The issue here is, the opponents have already exchanged information about their hands. They know opener has spades and responder has clubs, and that they have game values. If the hand turns out to be a misfit, it will not be hard for them to double you.

Bidding won this time because: (1) you had a double fit (2) opener guessed wrong about what to bid at the three-level (3) responder made a very undisciplined 6♣ call with no control in either of the red suits. In general I think 2NT here is not a very good call. I'd pass on the actual hand, although 2♥ is close (I'd bid it at favorable) since the danger of being doubled at the two-level is somewhat less.

I would Dbl, because I don't think the 3-level is safe enough. That wouldn't take away opener's 2♠ rebid, so I guess 2NT is probably better.

(Dbl doesn't show values, just the other suits, since opponents have enough strength for a 2/1)

I understand the will and the need to disturb opps well defined bidding system. But do they really have no tool to cope with a 2 NT bid?
So, maybe the choice is more between pass and 3 NT to take away even more space?
But I must admit, that Istopped bidding two suiters if I am not really willing to play in my suits. It is just to easy for declarer to play the hand.

So, I would sit and wait, jiust acting in fab.

Apology for a rather basic question,
Does 2♣ always guarantee 5 cards?Isn't it usually 5 cards,often 4 cards and sometimes 3 cards?
A trifle less basic .Wouldn't 3♠ show 6 cards and also support for ♣ if P has them and no desire to punish ops in their suits with its consequent conclusions?
