Partner's pass showed an 11-13 bal hand unwilling to make a support redouble.
Does 3♥ show this hand? What are double and 2♠ in this position?

From a Polish club point of view I would expect 3♥ to show that hand (well probably 1-2 points weaker in PC as the weak variant is 12-14 for us so this would be a GF), yes.
2♠ would be something like a 24(34) invite+ and X show a fifth heart, competitive+. (though this depends on how often you choose not to support X, I guess.)
