-<h2 style="clear: both;">Symbol explanation</h2>
-<ul>
- <li><strong>Score:</strong> 1.00 is the value of one pawn (in the opening). Positive values are better for white.</li>
- <li><strong>PV:</strong> Principal Variation, the series of moves the engine thinks is the best.</li>
- <li><strong>Thick red line:</strong> Marks the best move (in the view of the engine). Multiple chained arrows
- means that the PV starts with multiple successive moves with the same piece, ie., the engine thinks
- that the piece will execute a maneuver.</li>
- <li><strong>Thin red lines:</strong> Other good moves, maximum two. Note that even though these are also
- quality checked, these are less thoroughly analyzed by the engine,
- and should be taken with a grain of salt.</li>
- <li><strong>Thick blue line:</strong> Marks the best <em>response</em> move. Note that this is only rarely shown,
- since usually, the best response move depends on what the first move is. A typical case is when the current move
- is forced or nearly so.</li>
