possible calls look to be Pass, 3♣, 3♦,2♠. Clearly pass is the straight and narrow call while 3♣ is a psyche. 3♦ makes it harder for the opps to find ♣ but you can only make this call if you are playing RONF, 2♠ while it is your suit do you really want a ♠ lead and of the other 2 suits ♣ is easier to bid because ♥will be available to the partner on the same level.
