Where a set number of valid places are declared by the bookmaker (e.g. 1st, 2nd and 3rd). Your 'place' bet will win if your selection comes within this range.
In large fields, the place may be 1st, 2nd, 3rd or 4th, in smaller fields, 1st, 2nd or 3rd. The odds are shorter for a place bet than a win bet.
