where can we see pawn and other

You smile at chess? Chess is srs business! There is no smiling in chess! xD

Yes...the majority of the smiling tends to occur outside of a game.

During a game there is much trouble. Hardness, trepidation, struggle, weight, tension, anxiety. There is also relief, gratitude, greed, hope, and myriads of other feelings that are neither "negative" nor "positive".

I surely smile more in the real world, than in the world of Black and White.

#11 you can smile while playing chess. For example, in the moments like this: http://en.lichess.org/oWJkanix#84.
