    "abstract": "We revisit the path integral description of the motion of a relativistic\nelectron. Applying a minor but well motivated conceptional change to Feynman\u0027s\nchessboard model, we obtain exact solutions of the Dirac equation. The\ncalculation is performed by means of a particular simple method different from\nboth the combinatorial approach envisaged by Feynman and its Ising model\ncorrespondence.",
