3NT seems pretty obvious (assuming standard bidding).

Our rules are 1. partners signal is attitude unless it is absolutely clear to both partners that attitude is useless. I was thinking about the possiblity of partner ducking ♦A playing me for ♦doubleton, when I said I believe this is an attitude situation. 2. Second priority is count. Obviously count can be useful here since it can tell me whether I can afford passive defence. 3. If both count and attitude are both useless then signal is attitude.

♠9. With no entries maybe it is right to try hit partners suit.

I think ♦6 is simply discouracing. Maybe from ♦10652. If that is the case we can count declarer 11 tricks so we should start cashing black aces. ♠A first and ♣A next and partner will show attitude to indicate in wich suit (if any) he holds the king. I dont believe pass should be forcing here. 4♠ doesnt show any defensive strenght.

I would have thought that double is for penalties. Guess I need to learn new meta-rule like "low-level doubles are always take-out if that makes any sense".

I chose ♠Q but it seems like a complete guess to me.

Does not rhm`s line require guessing EW distribution correctly in the ending?

I would have tried entering dummy with a trump and low spade from there.

It is close but I would not. There is no guaranty of a decent fit or finding the right part score. 2NT could work very badly if partner is 4423. And after double he would often bid ♠ when 3minor is right.

1. Competitive double. About 10-11 hcp with usually 4c♠. 2. I much prefer 1NT in first round. Maybe second double should be penalty oriented eg hand that is too strong to bid 1NT in first round and usually no ♠ support?

Not much blame here. However I think that South is worth a false preference to 2♥ after wich partnership will end up in 3NT or 4♥.

I would rather run the ♥10. Opponents might duck ♥9. Now you run the risk of losing 2♦, 2♠ and ♥A even with hearts right all the time.

The trouble with 2♠ is not that 2♠ is likely to be too costly. The trouble is that South will expect more and will either overcompete or when 3♠ is making he will bid game going down again. As for getting them to tree level I do not think that they are going down. Maybe I am wrong but as I see it 2♠ has very little upside to it. Does anyone really think 2♠ making will buy it? Do you really expect to make 4♠ if South bids it?

Since I usually play new suits nonforcing responding overcalls I would bid 2♠ instead of 2♦. Obviously the hand is minimum even for nf 2♠. You would also want a better suit since partner might pass even with a singleton if he holds a bad hand. Still a spade game is possible if the hands fit well.

I voted mainly because I might want to kibitz the game so you may disregard my vote on other issues.
