        <p>Ordinarily, a single CPU thread collecting multiple evaluations to batch, or multiple CPU threads creating larger or multiple batches, would choose the same position to evaluate many times following the deterministic SBLE-PUCT/AZ-PUCT process, undermining the purpose of batching. Virtual exploration and virtual loss allow each parallel PUCT search to choose a different position by giving a slight, suboptimal nudge t
