        <p id="sble-puct">With ChessCoach I introduce a new method, <em>SBLE-PUCT</em>, based on Linear Exploration and Selective Backpropagation, applied via elimination. The primary danger of exploring too much is that value is diluted in ancestors. SBLE-PUCT tempers this by breaking the assumption that evaluations are always propagated all the way back to the root. In its metric form, it encourages minimization of simple regret after a delay by adding a linear exploration term t
