\begin{center}
	\pgfgouseprofile{pgfgo}
	\begin{goban}[10x2, label = {at = {all}}, scale = 2]
		\stone{A1}
		\moves[b]{A:D2}
		\stone[w, mark = {triangle}]{D1}
		\moves*[b]{G1--J1|-G2}
		\mark[b, t-circle]{E1}
		\mark[w, t-square]{E2}
	\end{goban}
\end{center}


We declare all players and start by defining the appearance of the neutral one.

\begin{codeexample}[code only]
	\pgfgodefineplayer{pgfgo-neutral}{
		stone = {
			radius = 0.19cm,
			line = {
				true,
				color = black,
				width = 0.3pt,
				opacity = 1,
			},
			fill = {
				true,
				color = gray,
				opacity = 1,
			},
			radius = 0.17cm,
			scale = 1,
			drop shadow = {true, opacity = 0.5, offset = 1pt, angle = -45},
			drop shine = {true, angle = 45}
		},
		move = {
			label = {
				color = black,
				format = arabic,
			}
		},
		mark = {
			line = {
				color = black,
				width = 1pt,
			},
			fill = {false},
			label = {
				color = black,
				format = arabic
			}
		}
	}
\end{codeexample}


Some properties such as line thickness, opacity, and others should be preserved for all stones, so we copy the neutral player template.

\begin{codeexample}[code only]
	\pgfgodefineplayer[from = pgfgo-neutral]{pgfgo-white}{
		stone = {
			fill = {
				color = wainwhite
			}
		},
		move = {
			label = {
				color = black
			}
		},
		mark = {
			line  = {color = black},
			fill  = {color = white},
			label = {color = black}
		}
	}
	
	
	\pgfgodefineplayer[from = pgfgo-neutral]{pgfgo-black}{
		stone = {
			fill = {
				color = wainblack
			}
		},
		move = {
			label = {
				color = pgfgo
			}
		},
		mark = {
			line = {
				color = pgfgo,
			},
			label = {color = black}
		}
	}
\end{codeexample}

\subsubsection{pgfgosmooth}
\begin{center}
	\pgfgouseprofile{pgfgosmooth}
	\begin{goban}[10x2, label = {at = {all}}, scale = 2]
		\stone{A1}
		\moves[b]{A:D2}
		\stone[w, mark = {triangle}]{D1}
		\moves*[b]{G1--J1|-G2}
		\mark[b, t-circle]{E1}
		\mark[w, t-square]{E2}
	\end{goban}
\end{center}

\begin{codeexample}[code only]		
	\pgfgodefineplayer[from = pgfgo-neutral]{pgfgosmooth-neutral}{
		stone = {
			line = false,
			radius = 0.19cm,
			drop shine = {opacity = 0.5}}
	} 		
\end{codeexample}
