I don't understand what chemistry is. I tend to be very black and white in my thinking and as such I used to think that attraction takes place on a purely physical (visual) level, which is clearly not the case.

"Game" is obviously the ability to create chemistry or the illusion thereof. This is necessary to attract a partner as a man but it's not exactly possible to work on it when it's a completely foreign concept to you.

What brought this question to my mind was actually GOT fans complaining about the lack of chemistry between lead actors Emilia Clarke and Kit Harington. Using my initial perception of how sexual attraction works you'd think that there would be attraction between them as they are both attractive people, yet according to critics there was no chemistry. Watching the series myself, I can also pick up that there is something "off" about the way they interact although I can't exactly put my finger on it and I want to be able to understand it better.
