Stripe-Tail Ape double is when you double opponents in a making contract (usually at the five level) to prevent them from bidding a making slam. This is an occasional topic of bridge stories, and also happens sometimes by accident. Have you ever made one of these doubles on purpose?

I have done this fairly frequently, especially if prepared to sac in a higher-ranking suit. For instance, I have had occasion to double a 5♥ response to RKCB, the opponents holding hearts, when I was otherwise prepared to bid 5♠.

The other example, albeit technically just F-ing around, is the striped-tail-ape-and/or-check-whether-the-blues-discussed-ROPI double of 4NT.

I've only done this once. On the last board of the club championship in the club I played at the time (1983). We were playing one of the stronger pairs in the club. I had a near yarborough hand and early on was pretty sure they could make 6♥. So when RHO replied 5♥ to BW, I doubled, and all passed.

Early on, my partner won a trick, which was ok. Then he won another, and I didn't like that at all - had I doubled them out of a non-making slam? At this point the rest of the tables had finished play and all were kibbing our table. Partner got another trick, so we set the contract. It was a Howell movement, so we soon picked up the traveller, discovering that all other tables had played 6♥..... and made it!

So my double won twice! :)
Kind regards,
Harald

I don't play enough in Matchpoint events. Because of that, on the few occasions that I do play in them I tend to forget the opportunity when it arises. Strictly a technique for use against intermediate opponents, I think.

Once: The opponents had agreed ♠ and were in a cuebidding sequence, and I had Jxx xxx Jxxxx xx... finally they bid RKC, and I doubled their 5♠ bid. Partner, not knowing any better, took this as lead directing and led a small ♠. Ironically any other lead gives declarer a trick and several tables made 7... They made 6 against us, -1050 is rarely a top :).

Have had several unintentional versions. One worked out fabulously well when I doubled a 0-3 RKC response (happened to be their trump suit too) causing a mixup and a missed grand.

Have made one purposeful STA.

the striped tailed ape X is almost as worthless as the SOS XX. Big downside, almost no upside.

Yes exactly. Seems very convenient to me. If you think it has no upside then you have been living on a different planet than I have.

I live on Neptune (See my profile on BBF) and we neptunians find the SOS XX extremely valuable! Maybe the martians have something against it? :rolleyes:

It's not "sacred" but there is nothing to replace it and it's such a valuable tool. I don't know about your partners, but mine open very very light on their weak 2's meaning that an SOS XX comes up quite often... It has taken us from -1100 to -100 or even sometimes making! I'm not sure what you are suggesting in place of it... In fact there was just recently a thread about whether buisness XXs are valuable where Frances posted a beautiful explanation of why they are not.

Not a sacred cow Bill, but IO also disagree with you. I have used an sos xx many times to escape a crappy fit and find a far better one.

I think I've unintentionally stripe-tailed ape once. I can think of at least a dozen times where an SOS redoubled worked well.
