t faced this hand as North recently. A number of questions I'd like to ask from different directions here:
1. I recognize this as perhaps a "perfect psyche" in a number of regards: (a) partner is not likely to go crazy having already described his hand, (b) they have a perfectly safe way to escape if doubled, and © favorable vulnerability. So seems like this psyche is virtually all upside and no downside. Does that sound right to folks, or am I missing something?
2. Are there many other types of psyche's that are similarly perfect with such little downside risk? I now have this type labeled in my mind as "Big fit for partners pre-empt suit, void where opps will have game/slam, psyche the void"...are there other types of "perfect psyche" I can review to either recognize or use myself down the road?
3. What would you have bid ATT as NOrth? I suspected a psyche, but wasn't certain. And not sure I had methods to penalize it if I was sure; X here would likely NOT be interpreted as penalty by partner (although we don't have specific agreements). I doubled hoping partner had a 5-card major to bid; I got lucky that he did, he got unlucky with the 5-0 trump break but was able to manage.
4. I have no problem with psyches generally or in this specific instance, but just from a process perspective should we have called the director to "register" that there had been a psyche? Does location/setting matter here (this was in two-session open pairs at ACBL regional).
5. Now that East has seen his partner make this psyche, does he have any obligations for the future? That is, the next time he pre-empts at the 3-level and his partner respondes over a TO X with a new suit, is there any alert required like "partner has psyched in this situation in the past"? This seems unlikely because I would think the vast majority of similar situatinos (from East's perspective) would NoT be psyches. But I have heard that this type of alert is required in some situations...so when and under what situations would that be?
6. For resulters, the psyche worked reasonably well for them here. We got around 35% in 4H=, losing to folks making 6D= and 5D+1. We did beat a couple of pairs in 6D-1, and presumably some tables who were in 7CX-3.
1. This is indeed a very common auction in which to psyche. I have the (dubious) pleasure of reviewing all recorded psyches in EBU events, and the two most common are dodgy 1NT openings in 3rd seat and invented suit opposite a pre-empt with a fit - just like this. The downside is that you haven't taken up much room: you are allowing the opponents to start investigating their best contract at the 3-level. Against good opponents I'd rarely bother psyching with a big fit, I'd rather just bid (say) 6C and leave them to guess. On this hand you might bid 3D to get partner to lead a diamond against their slam: that's the advantage of doing it on a void. If you want to keep them out of a making slam, you are actually better off not having a void (when it can get too easy for them): if I had something like Jxx xxxxx x AKxx and the auction started 3C x I would rather bid 3S than 3D.
2. Your description is correct for the most obviously (virtually) risk-free psyche. The other one is the psychic cue bid or trial bid (sometimes called a 'sting' cue) when you cue the suit you have 2 low in, to stop them leading them. There are plenty of other common positions for psyching, but they have bigger risks. The best psyches against good players are the most risky ones, because they are harder to deal with: the 'safe' ones are sufficiently common that most regular partnerships have agreed ways to exposing them however very few players can find their 6H contract when someone opens 3H on KQJxxxx x xxx xx against them!
3. Sorry, but the only answer is to double for penalties. That's why people psyche against pairs like yours: if you don't play penalty doubles here you will be taken for a ride. Good general rule: if partner doubles one suit for take-out, double of a new suit is penalties. Even if you don't like this after a 1-level take-out double, you have to do it after a pre-empt (e.g. 2H x 2S x). You've already explained in point 1 why this is such a good psyche: that's why people do it a lot, and why you have to play double as penalties to counteract it.
4. No harm in getting it recorded, although it's not an irregularity (as suggested elsewhere) by itself.
5. If they are a regular partnership, and West often psyches on this auction, eventually it becomes a partnership understanding and alertable. Once is not enough.
