Some initial thoughts:
Problem A: 5
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
- The opponents preempted in 4
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
and partner has made a two-suit takeout, and I have two doubletons with 12 HCPs. If partner can commit to the 5-level with me as a passed hand, I am willing to be in his best suit in slam. He surely only has at most one spade, I have two rounds of control in hearts and a good honor in one of his suits, time to go slamming.
Problem B: Pass - If the suits were reversed, I'd have no problem preempting in spades and backing in with hearts. With my length in hearts, I think I will simply back into the auction later or see it go quietly into the night.
Problem C: Pass - I am torn between bidding 2
![Hearts Icon !H](http://iac.pigpen.org.uk/smf/Smileys/default/icon_hearts.gif)
and passing. Partner is saying that he has at least one stopper in spades, some values and implies a lack of a heart fit. My sixth heart may be enough, but it might also be useful in NT. We also could be down one to making four - where in that spectrum do we belong. Today, my willingness to risk is not many tricks, but in NT.
Problem D: 3
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
- I presume that the 3
![Diamonds Icon !D](http://iac.pigpen.org.uk/smf/Smileys/default/icon_diamonds.gif)
overcall is preemptive, but there is no note. After all, we are in a game forcing auction and they jumped to eat our space. This does not sound like a penalty double to me today, so I bid my spades. By the time I make a final decision, I may be ready to pass the double.
Problem E: 6
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
- This feels like a slam despite the opponents doing all of the bidding. All I need from partner is four points (
![Clubs Icon !C](http://iac.pigpen.org.uk/smf/Smileys/default/icon_clubs.gif)
A or the two round queens) and may be gin with just the
![Hearts Icon !H](http://iac.pigpen.org.uk/smf/Smileys/default/icon_hearts.gif)
Q if I right side this. If I try 6
![Diamonds Icon !D](http://iac.pigpen.org.uk/smf/Smileys/default/icon_diamonds.gif)
to get partner to choose a major, I would wrong side this hand, so I pick the more secure major.
Problem F: 1
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
- If 2
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
is preemptive, I would prefer that bid. This hand will be worth so much more in spades than anything else, but if partner rebids 2
![Hearts Icon !H](http://iac.pigpen.org.uk/smf/Smileys/default/icon_hearts.gif)
, I would subside. 2
![Hearts Icon !H](http://iac.pigpen.org.uk/smf/Smileys/default/icon_hearts.gif)
and pass are also possibilities.
Problem G:
![Diamonds Icon !D](http://iac.pigpen.org.uk/smf/Smileys/default/icon_diamonds.gif)
10 - I have two reasons to try the diamond shift. One is that if clubs can be set up, then diamonds may be the outside entry. The other is partner's card to my lead could be suit preference - then again it could be a singleton.
Problem H:
![Spades Icon !S](http://iac.pigpen.org.uk/smf/Smileys/default/icon_spades.gif)
10 - At best, declarer is looking at 7 spades, but may have less. I have two probable entries, but really no suit to set up myself, I so will try to hit partner, and use one of my entries to continue the spade attack.
