Couple of Failures at Slam Bidding

Have not posted for a while as I have been travelling and busy a lot the last month, but home and playing again. And coming up with some not so good examples of slam bidding.

On the first, you pick up AQT74 2 --- AKJ8753 and hear partner open 4C (Namyats) in first seat. Oh well, so much for playing in a Black suit. At least you have 1 Heart and a good void, not the other way around. You bid 4D, which asks for partner to describe their hand, and partner makes a bid you have not talked about, 5S, which gets doubled on your right.

Over 4D, you have agreed to play 4H showing a suit with 1+ losers, 4N shows no suit with 2 quick losers, and 4S/5C/5D show a suit with 2 quick losers, and imply no other suit with quick losers. You have not talked about much else in the basic discussion over these bids. So you are on your own with what partner decided 5S would mean.

You eventually decide to redouble this, and partner now bids 6H. You are assuming that 5S was a void, with no suit having 2 quick losers. The question is, does partner have solid Hearts for this auction. You decide that he should, and raise to 7H. This is not a success when partner holds
--- AJT87432 AKQT 9.

I held this hand and decided with the lack of defense coupled with a 2 loser hand, I did not want to start with 1H and lose control of the hand (what if one of the opps help partners hand). But over 4D, I decided if partner was asking about my hand, I was going to slam. The problem is I kind of got too cute, and decided to try to describe my hand now, with disastrous consequences, sigh.

On the second hand, you hold AQ T843 J3 KQ852 and over partners 1D opener, decide to bid 1H. Partner bids 3S over this, showing a splinter in Spades and a game forcing Heart raise. Is this enough to move over 4H with?

I figured that when I worked on the splinter values principle, I had 10 working points to add to partners supposed 18-19 min, giving us well over the 24 required to look for a slam opposite a splinter, so moved forward. I should probably go slow and bid 4C over 3S, letting partner asses their hand, but I think we will wind up in the same spot in 6H. Partners hand is 4 AKJ7 AT854 AJ3, right at the bottom end of the splinter and with poor Diamonds, so when the Heart Q is third offside, there is no way to avoid 2 losers. On the hand, I actually just jumped to 6H over the 3S bid, getting there quicker.

At the other table, the strong hand jumped to 4H over 1D-1H, which I think should make my hand even more interested in slam, since they think the Q of Spades is working and the Spades are protected on the opening lead. But they passed 4H and were right, winning 12 IMPS :(

Will try to get back to keeping this up to date, and stay home a little more.
