Ah, some cheapies are the business, however elderly. Leader Board is, of course, the golf simulation, and months after its first appearance, it's still a cracker.
The secret is its simplicity. It's easy to play, so that anyone with enough patience to read the instructions can get going without delay, but very tricky to master, especially once hook, slice and wind have been added into the equation. Detailed though the instructions are, this cheapie version does not include the valuable course maps that were featured in the full price deluxe thingy, which is a pity, but then you can't expect everything for two quid.
No doubt someone's trying to better this on the 16-bit gizmos as we speak, but I can't see that anyone will ever come close to it on the Spectrum. Now where are my silly trousers? Fore! [I thought you gave it eight - Ed]
