Double-blind review with four references in a row?
Describe those works in the third person but do not anonymise the references. For example, "Doe et al in their work show that..." Even if you are Doe. Very often I review papers (in CS/HCI) whose authors have blanked their past work that they reference. This makes it very hard to judge the quality of the new contribution if compared to the previous work, and it is bad practice in my opinion.

The side effect is that it is conceivable that they could guess who you are, but it is less of a problem than not being able to judge the quality of the contribution, IMHO. If the venue allows it, after acceptance you can change your "Doe et al" with "In our previous work.."
