From The Overcall Structure

The Roman Jump Overcall
The two cheapest jump overcalls over a one level bid by opener show the suit bid and the higher touching suit with generally 6-15 HCP. There will always be at least nine cards in the two suits. If there are only 9cards, the lower ranking will always have five cards and the higher ranking will have four.

The bids are asfollows with minimum holdings and tendencies:
2/1: 5 and often 4
2/1: 5 and often 4
2/1: 5 and often 4
2/1: 5 and 4; 5-5 if vulnerable
2/1: 5 and 4; 5-5 if vulnerable
3/1: 5 and 4; tends to be 5-5
3/1: 5 and 4; tends to be 5-5
3/1: 5and 4; tends to be 5-5

The point ranges and limitations are very sensitive to relative vulnerability. Non-vulnerable vs. vulnerable opponents, 2/1 with Jxxxxx Txxxxx x --, would be acceptable. Vulnerable vs. non-vulnerable opponents, 2/1 with KJxx AJxxx Qx KQ, would be reasonable, as opposed to a double, especially opposite a passed partner. One hand that you will never have is 4-5-3-1 shape with shortness in opener's suit because that is a NTTO.



How does this in any way allow you to bid the opponent's suit?
