HAL's opponent current candidate for play is the 6D. You wish to select the 9C.
Selection is a 2-step process. Choose the 9C as a candidate card by clicking on the 9C in the 13 x 4 grid of available cards. This will show the 9C card in the opponent's hand.
To confirm it as a selection, click the 9C card in opponent's hand.   (The 10S will show as the candidate for opponent's next card.)
If opponent is in a Go state and opponent's GO box is NOT visible, select ANY NON-legal card. This will cause opponent's Go box to appear so that you can click it and put opponent into a Go state.
If you make a mistake, click Action - Reset to start over. The hand will be cleared and scores reset.
