For the July one:
Always go first.
Assuming the table is symmetrical around only one point, the centre of the table, place the first coin on that point.
Every move after that place your coin in the location directly opposite the last coin played, the mirrored location around the point of symmetry.
Since you are always playing a symmetrical position, you know that there will always be a space available for you after the previous coin was played.
[edit] looks like the answer on the site is almost the exact wording as mine :)
- datr 10y agoThis is actually very similar to a question I was asked when interviewing to read Maths at Oxford. In the Oxford version, your brother and you are also playing a game. You have a 2-dimensional block of chocolate with a poison piece somewhere in the block. The poison piece is bright green to the eye. You each take it in turn to break off some chocolate (you have to follow the rows and columns of the chocolate, and the break must be a single break). To win you must avoid eating the poison piece and end the game by handing it to your brother. You have the choice of going first or second? When should you choose either?
