I believe this is Common Snipe. The contrast of buff super with white cheek stripe is typically shown by this species. Further, the pale mantle lines are distinctly buff and rather warm in tone.
The reason it only has two of these lines is that the bird is in moult, and one row of scapulars is almost all absent. This is why the grey bases to the feathers of the lowermost scapulars are so visible.
The 'pin' you see on the tail is not the pin referred to in the name. If you do a search on the web, I guess you should be able to locate a photo of the tail of Pintail Snipe.
