It's between 3S and 4S. I would go 4S but wouldn't criticise anyone who only bid 3. It is likely to get doubled. If it's 800 then I hope they have slam on, otherwise it should either make or be a good sac.
And Pirate22, do your partners expect you to have 7 clear tricks in your own hand for your 2S? If not, then partner is going to misjudge very often.
