There are some good hands this morning
1. What's happening in spades? What doesn't pard have? Not the Q-J; he'd split. Not the A-Q; he'd win. A-J is tough; but pard really should win and fire a club. A-empty is the toughest, but that probably requires the same logic as AJ-empty. Q-empty is tough too, but he'd probably duck. So Pard probably has a real lousy suit, and it should be 6 cards in length.
2. Declarer certainly has a stiff or void diamond, otherwise he wouldn't be ducking a heart to me (what's the point?).
3. So I'm putting declarer on something along the lines of
♠AJx,
♥AK87x,
♦x,
♣????
This alone gives him 7 tricks. If declarer has the
♣AK; its 9. With the
♣Axxx, its silly to duck a heart to me; once you see the heart split, you have to go after
♦'s. How about
♣ATxx? There's some appeal to ducking the heart to rectify the count for a
♣/
♥ squeeze against me, or an endplay. This would leave partner with a hand like:
♠Qxxxxx,
♥void,
♦Jxxx,
♣Kxx; barely enough for a one level overcall.
I haven't thrown away the idea of a diamond void either. My fear is that if I don;t do something active; with a stiff diamond, declarer might go after diamonds is I try something cute, like laying down the
♦Q.
So I will play a small
♣ (The Q makes it too easy to duck), and hope declarer duck's pard's (presumed) King, Will I get endplayed later? Possibly, but declarer is about to grab a 3rd trick
♥ if I don't get busy now.
The other possibility is that declarer is just wide open in clubs, but if thats the case, this is an easy hand to beat with a club shift.
(What's that...I just noticed pard's club pitch? This makes about zero sense with my construct of the hand, so I really don't know what's going on...

)
I'm probably missing something here, so I'm really curious to see what happens.
