Were you able to see how Gold could establish a material advantage in the initial set up phase? There are actually multiple answers. G6, A2, B2 and B7 all work, but in the game referenced Gold placed a stone on G6.
No matter what Silver plays now, he can’t prevent Gold from having an extra stone. The sequence that followed is found below.
Gold G6 Silver B3
Gold B7 Silver G1
Gold A1 and Silver has nowhere else to place a stone.
