Well that was interesting.
The first game went well for me and i seemed to be playing reasonably well. I won the game but Jack certainly kept me on my toes. The second did not go so well. I was on the back foot trying to defend with every single tile. i could not go on the atack as my poor tile draws, jacks good tile draws and jacks skill just kept pushing and pushing. His last tile took the game making the 5 point difference.
