I don't get it

Whoops forgot to put a title on my last one

Now, can anyone explain why Black throws away a pawn on his last move in this game:Game 623311

I am hopelessly confused. Please help me.

(and again😛)
It is not good to tell something about a game in progress

Oops. I'm sorry. After the game then.

Wait till the end of the game and your question might be answered anyway. 🙂
