When Gordon told Hanson that he was considering selling his house, Hanson offered to buy it. Gordon and Hanson entered into a contract in which Hanson paid Gordon $1,000 in cash for the right to buy Gordon's house for $150,000 in the event Gordon decided to sell it. Two weeks later, Jones offered Gordon $200,000 for his house, and Gordon agreed to sell it to her for that amount. Hanson sued Gordon to force Gordon to sell the house to him for $150,000, rather than to Jones for $200,000. Identify the probable result of the action.
