First time playing with this partner at a club game, partner is adv+.
My general bridge knowledge would have me believe this showed a 5-4 hand and inv values.
My partner felt it showed a very weak single suited spade hand, to weak to bid 2s and not really wanting to preempt at the 3 level.
I have to admit his interpretation has a lot of merit, just odd that I have never seen or heard of this before.
Is this pretty standard stuff?
