Combative Draw (Draw Accepted)

Hi! This is pete-2. Look at this game. Positions are equal, but White has advantage, because Black King is away from his side. First time White declined draw offer, but after many repetitions White accepted it. Interesting game I called "Combative Draw". I think, it's really combative draw. English Opening with second move ...a6 after 2.Nc3 looks like strange, but it's not weak move. The game showed this and other tactical moves by Black.
