I'm a fan because it's a good contrast. A high class environment with anything but high class behavior going on inside it. The betting aspect is pure Bond as well, evoking Octopussy. I've always loved that brave and defiant side of the character. Backed up against the wall after losing twice, and then bringing the diamonds into it. Going all in with his everything or nothing philosophy. It mocks the villain and gives a false sense of security. Because Graves is clouded with rage and thinks the battle will be simple.
I love the sword fight
Yeah, I love the look on Grave's face after Bond takes the diamond out of his pocket. This shows a bit of weakness in Graves and how 007 may have compromised his cover story as someone discovering a diamond mine. It was pretty good. Bond showing his strength and how he's not letting this competition cloud the situation. I mean, Graves knew it was Bond all along with the whole, "Have we met before?" But Bond, having no idea who he really was still got to him.
