I've been derelict in my self-flagellation duties lately, so here's another one I didn't get right:

Same set with Jeff against Izzy and Sylvia, in 4th, all white:

AJ92 / AQ43 / KQ84 / 4

4 Spades pass, pass to you, and sadly you're playing takeout doubles through 4 Hearts.

Go or no go? 

I've never liked playing double of 4 Spades as takeout, but certainly there are many hands where I'd be glad we were. Unfortunately, this isn't one of them. I resigned myself to losing 5 or so and passed. Jeff led the club ace and dummy tracked:

T / K82 / AT96 / Q9832

Doh.  If Sylvia has a normal 4 Spade bid, we could be cold for 6 Hearts.

I was so busy trying to figure out what we should be in that I didn't pay sufficient attention to what we were in and managed to hold the defense to 5 tricks (Jeff gave me a club ruff, setting up dummy's clubs, and when I got back in I didn't cash my ace of hearts) instead of the 6 we were supposed to get after a club lead.

Jeff held

8 / J9765 / AKJ6 / 732

Sylvia had made a winning aggressive call with:

KQ76543 / T / J5 / T75

(I confess, it would never have occurred to me to bid anything other than 3 Spades in 1st seat.)

But back to the bidding question ...  Notice that I have a play for slam opposite EITHER Jeff (6 Hearts) or Izzy's (6 Diamonds) hand, that certainly argues for doing something. 

-100 was worth 6.8 IMPs for the ladies.  6 Hearts can be beaten, but it wasn't the one time it was played (defender popped on the first diamond, and that let the minor suit squeeze come into play.)
