Spoiler forOk, how about this? Bob just removes the coin opposite Alice's every turn. This guarantees that Bob always has a move since the board will always be symmetrical (every coin always has a coin opposite of it, and the board seen from the point of view of any coin is the same as it is seen from the coin opposite, except flipped) and removing a coin never affects whether its opposite can be removed (since a triangle formed by a coin and its opposite and any other coin is always right angled).
remember right angled is not considered acute in the game's directions

The 'best answer' will be awarded to the person who can develop an elegant method that does not utilize brute force or code.

#332586 Rolling a coin
Posted by BMAD on 27 May 2013  12:43 AM
We have two identical coins. And we roll the one on the left halfway around the other coin, so it rotates without slipping against the other coin, so that it ends up on the right of the other coin. It has rolled over a length of only half its circumference, and yet it has made one complete rotation. Which way is the head of the coin facing?

Would this approach work in identifying those that always lie and those that always tell the truth? Why or why not?

#332584 parallelogram conjecture?
Posted by BMAD on 27 May 2013  12:25 AM
Start with any general quadrilateral, and connect the midpoints of consecutive sides, making an inscribed quadrilateral as in the diagram. That inscribed quadrilateral, in the diagram, seems to be a parallelogram. Let me conjecture that this inscribed quadrilateral is a parallelogram with half the area of the original quadrilateral. Can you prove or disprove either part of my conjecture?
