2 ♠is good. With a minimal hand (11-12PO) of the partner and with distribution 3-0 and with k in the wrong position it's hard to do and 2♠. If the partner has a stronger hand over 14-15PO he can say 2 clubs forsing an the auction can grow with 2♥-good hand or 2♠-minimal. Slam are hard with bad distribution.
I prefer 5♥ and i hope from my partner a hand : 2-3♠ with A,J or 2-3♦ with K,J,1♣ and 7♥with K, so 7-8 PO. Dbl not good because I don't have a defensive hand and i'm in vulnerable versus non-vulnerable. i prefer offensive.
