r/MachineLearning - [D] How to create a neural network for the game Ult. tic tac toe?

Hello I want to create a neural network for the game Ult. It is my first neural network that I will create. I want to have 90 inputs to the layer(81 representing the sub boards and 9 the global boards, -1 for occupied by O, 0 for empty and 1 for occupied by X). I want to include one or two hidden layers with 40 nodes each(Sigmoid function). The output layer has 1 output node ranging from [-1,1] representing 1 that X will win and -1 that O will win.
