Staggered fermions with smeared links can have greatly improved chiral properties. In a recent paper we introduced a simple and effective method to simulate four flavors of staggered smeared link fermions. In this work we extend the four flavor method to two flavors. We define the two flavor action by the square root of the four flavor fermionic determinant and show that by using a polynomial approximation the two flavor action can be evaluated with the necessary accuracy. We test this method by studying the finite temperature phase structure with hypercubic smeared (HYP) link staggered action on N_t=4 temporal lattices.
