Microchip: tapping the microchip has multiple functions depending on the play mode and who is to play.

• Your move in game play against HIARCS with white or black, the microchip will make HIARCS change sides, rotate the board so you are always playing up the board and start thinking.
• HIARCS To Play but not thinking: The microchip will make HIARCS start thinking. This can happen if you takeback moves or navigate to a position in which HIARCS is the side to play.
• HIARCS is Thinking: The microchip will make HIARCS stop thinking and move now.
• In two player no analysis play mode the microchip will turn on continuous analysis.
• In continuous analysis play mode the microchip will turn off analysis and return to two player no analysis. This analysis toggle is very useful while reviewing a game that has already been played since you can analyse those positions you are interested in and save battery life by turning off analysis with one tap when you don't need analysis.
