An event Receiver would indeed a possible solution here.You'd then override the ItemAdding event checking the Checkbox field value if yes and textbox is empty then cancle event firing and return false. Something like this:

  properties.Cancel = true;
  properties.ErrorMessage = "Item Must Required";
  properties.Status = SPEventReceiverStatus.CancelWithError;

Let me know if u done with this.

In list settings you can only set, that field is either required or not.

To do some more advanced logic, you probably would need to create Custom Field, and write your own validation based on values from another field.

Use of Event Receivers is of course another way.

Unfortunately multiple lines of text fields are not allowed in formulars.

If you can change Field2 to a single line of text then you can add a validation saying =OR(NOT(Field1),Field2>"")
