This is new type of race called ‘Optional claiming handicap’. It’s a mix between a normal handicap and a claimer. Connections can choose to run their horses from their correct handicap mark like in a normal handicap or make a claim of up to 7 lbs, in other words run their horse from a reduced mark of up to 7 lbs. It gives them an advantage in race but the risk is that the horse can be claimed by someone at a pre-determined price after the race, whereas horses running from their correct mark can’t be claimed. Hope it makes sense.
