How to visualise chess moves using a TikZ tree?

Question

I am building a chess repertoire and would like to visualise it as a tree using TikZ.
Below is an example of what I would like do achieve (source: https://kevinbinz.com/2015/02/26/decision-trees-in-chess/)

round nodes with alternated color,
moves on edges,
text in a last rectangular node (evaluation of the position).

Exact font, color code, node decoration and arrow shape are irrelevant.

Note. Any data can be used in the answer.

This should be enough to get you started:
documentclass{article}
usepackage{forest}
forestset{end node/.style={draw,rectangle, fill=green!30,minimum width=1cm},
           chess tree/.style={for tree={align=center,edge={-latex},s sep=1cm,l sep=1cm,
           where n children=0{end node, edge={-}}{delay={draw, circle,minimum size=1cm, 
           if={iseven(level())}{fill=white}{fill=black!20}}}}},
           move/.style={if n=1{edge label={node[midway,left]{#1}}}
                              {edge label={node [midway, right]{#1}}}}}
begin{document}
begin{forest}chess tree
[
    [,move=Be3,
        [,move=g5
            [{[1a]-3}]
        ]
    ] 
    [,move=Bh6
        [{[2a]-2}]
    ]
]
end{forest}
end{document}
