I think the strategy is that you need to try and get the biscuits with two in one jar and 1 in another and it is your opponents go. Because when you get to that point the opposition can either:

Take one from the glass with two in it but then you can just take on from each side and win
Take one from the glass with one in it but then you can just take two from the other glass
Take one from both sides but then you can just take away 1 from the glass with 1 left
Take two from the glass with two in it but then you can just take one from the other glass

However I think to win you have to be player 2 because you can go from what the player 1 has done and adapt your strategy to that
