agree.

2D, wtp?

dbl, wtp?

How about ♦J?

ditto.

I think it's a good slam. Yes, with C lead, slam fails. On the other hand, with D lead, you are home (unless it were ruffed). With a major lead, you have more than 50% chance, finesse or squeeze. That being said, I agree with the following sequence between regular partnership: 2C - 2D (promised something) 2S - 3S (slam interest) 3N - 4C (3N: serious 3NT) 4N ...

Agree. But still, pd should bid 3H, give pd the chance to choose between 4H or 3N.

I second that.

2S guarantees another bid, so 3H is forcing.

I voted for 3S.

1) bid 4S directly. 2) open 2H. 3) This is a little tough. I might or might not raise to 4S as North. As South I might double: over North's 2S, I would raise to 4S or bid 3H. 4) 1H is OK (on the borderline). But I would bid 2S over pd's 2H.

This is tough. I might pass.

I am voting for another "2S wtp?"

Though I like to open 1C with 5-5 or 6-6 blacks, I would open 1S with this hand. Spades was too strong vs. clubs, they can be treated as 6-5. And I would not open 1 weak 2 on this.

Well, with this hand, I would rebid 3D especially if pd rebid 2H, unless pd passed over my 2C.

I would bid 6D.

I admit it's a tough decision for me. If I want a swing, I might bid 6C. If I want to be prudent, I would double.

I am wondering why I didn't cash ♣A at trick 3 before exiting with 3rd ♥? Well, now I exit with a club.

In my system, there is no such call as 4S. The only choices are 1) 1S, the weakest and forced bid; 2) 2S, 8-11, depending on the quality/strength of ♠ and other honors; 3) 2D, game forcing (or forced to 3 level of agreed major); 4) 3S, 7+ (could be decent 6) S, weak hand. The last option was adopted with agreement only.

I would pass.

Win C in hand, heart to King and diamond back. If East has DA, whether or not he plays it, I am home: if he wins with DA, I need only one D ruff; if instead he plays small and my DQ/K wins, I can ruff 2 Ds in dummy. I loss 2S+1H+1D only. If West has DA and wins, I can still ruff 2 Ds since he doesn't have D left.

Small club toward 10. 1) Assuming West plays small and it losses to East, I play DA if East returns D. and get out with another D. 1A) East has DK and wins second D. If he returns a red card, I ruff in hand and pitches a club from dummy, and do the finesse again. If he returns club, I play 8. This line fails when East has DK and CKQX(x). 1B) West wins with DK. whether he returns a red card, I will do the same as 1A). If he returns a club, I play J from dummy. 2) West plays small and it losses to East. 2A) If East returns a club (he is likely to have DK), I insert C8. If C8 wins and West shows out, I cash CA and exit with 4th C and hope I will have no D loser. 2B) East returns a heart. I ruff at hand, pitchs D from dummy and eliminate D (ruff laston dummy) and get out with small C and I am home. 3) East plays CK/Q, I cover with CA, cash DA and exit with D. Whoever wins with DK, I am home.

Yes, I am for 4D (assume it is forcing, otherwise why would I big beyond 3NT?).
