When players don’t understand why it is ok to open 3
♣ with 7
♣ and 11 points and still call it ‘weak’ or open 1
♠ when they only hold 2
♠ and not alert the bid of course the TD is going to be called.
Fair enough too, its very confusing – we need someone (Ben

) to explain why players are permitted to do this... I couldnt in any intelligible way, it took me long enough to understand it myself.
It is a question of disclosure of partnership agreements. Specifically everyone should be disclosing their agreements with alerts when there is the potential for the opponents to misunderstand their bids. This would include conventional and artificial bids, and bids that are 'unusual' in nature by partnership agreement.
In this case, calling the TD over the 3
♣ opener is questioning whether EW have an agreement that the 3
♣ opener can be this strong and have failed to disclose it. In itself there is nothing wrong with calling the TD for this, although I feel that it is quite clear that there is no such agreement as East would bid 3NT if there was.
I would expect the TD to say that West has made a poor bid (or, if being pleasant, deviated from standard bidding) but there is no partnership agreement and hence no infraction and no reason to alert.
Most national organisations have established alerting regulations to reduce the number of alerts in the f2f game. For example, Stayman and bids above 3NT are often deemed to be non-alertable (as
everyone is expected to know them) but these regulations vary considerably by country. The
WBF Policy, and essentially the BBO suggested policy, is to alert everything.
With respect to players psyching a 1
♠ bid when only holding two spades, psyches are not alertable as, by definition, a psych is a major deviation from partnership agreements.
Hopefully this is clear.
Where it gets messy is players' concern about
concealed partnership agreements (CPUs) and
general bridge experience. Deliberately concealing your partnership agreements is cheating but this is very rare. Sometimes partnerships will have implicit agreements through experience: for example, if this EW pair had another similar 3
♣ opening, then they would have created an agreement that they are playing intermediate 3
♣ openers and they should be alerting appropriately (even though they may not have an explicit agreement).
Many of us on these forums debate/argue about the use of general bridge experience. In my opinion beginners and intermediate players have little of this and so adv/exp players should be alerting
their general bridge experience when playing them. Others disagree.
