Whatever occasionial victory it must give does not seem worth the price. [/QUOTE]

I assume you would prefer a jump to 3[sp].
However, many play 3[sp] as promising a very good suit: AKQxxx would be a minimum, and for some inadequate.
Why? Because this use, while rare, greatly eases slambidding. Responder can begin to count tricks, and cue-bidding (and/or keycard at some stage) comes into play immediately.
You don't have to agree with it: but it may explain the 2[sp] bid: indeed, I would never to anything else

I too love 2s here, promising a 6 card suit very often which allows partner to bid 3s, slam try, please start cuebidding opener.

. It was the nebulous rebid of 2S that I dislike but I understand most disagree with me.
