4C to show a long club suit and spade fit is certainly very playable if you play double to show extra values, no spade support and doubt in 3NT. Still, it's not standard. Also, it's kind of rare. Usually you need a rather strong hand to force to game facing a free bid at one level. Anyway, the hands you want to bypass 3NT to bid 4C naturally are also very rare.
I don't really think this topic really deserves a lot of discussions. Still, any bids other than 3S are obvious overbids for this hand.

I really enjoy that .
So i got the point.
1. Dave bids 1
♠ having q10xx xx kxxx xx
2. 3h is sort of preempting hand
3. Mr Ace overcals 4cl having xx xx Ax(x) kqjxxx(x)
So E has about 20 hcps but he just overcaled 1

Conclusion:
Mr Ace will be in trouble if he plays with Dave
