This Letter concerns the problem of non-ideal state transfer along the alternating open chain of spins s = 1/2 with the XY Hamiltonian. It is found that the state transfer along the chain with even number of spins N (N = 4, 6, 8) may be realized with high probability. Privilege of even N in comparison with odd N is demonstrated.
