Price of Information

On a related note to the "steppingstone Bid" is "Price of Information" Series.

Partner passes, and RHO opens a strong 1NT.  White on red, you overcall 2C because you are playing Cappelletti and have a one-suited hand.  This call is alerted as such.  LHO doubles, passed to you.

So, you bid 2D, alerted by partner as showing a one-suited hand.  The opponents ask if that means diamonds, but partner says, "nope -- could be any suit."

The idea is that you play a series of calls above 2CX as all one-suiters without specificity as to which suit.  If the opponents really want to know, then they must double you and find out with a final pass, but then you end up declaring. 

This maneuver, properly alerted, cannot be deemed a  psychic.  Rather, it is "steppingstone-ish" in that the opponents cannot leave you in your contract undoubled and therefore must take action.  However, you are obviously creating a tactical problem for them.

Moreover, this sequence also is "steppingstone-ish" in that it compounds definitions.

If one way to 2S is 2C-X-P-P-2D-X-P-P-2H-X-P-P-2S, then 2C-X-P-P-2S shows something different, as does 2C-X-P-P-2H-X-P-P-2S.  If this situation presents itself, this may call for some discussion.

Of course, there is a defense to the "POI Series."  LHO stops doubling and lets RHO start the doubling.  But, this defense is only partial.  Sure -- it eliminates the box of being forced to defend our contract doubled.  But, it still forfeits definition somewhat for the opponents and it still gains us bidding space to fine-tune whatever we might want to fine-tune.
