Dream: Soccer Chess

My friend Mike and I had met. We were planning on playing a game that was a combinatoin of Soccer and Chess except in the dream it wasn't a combination. It simply was both. He was studying strategies, specifically attacks through the center of the board/field. I was busy with something else, and so I wasn't studying strategy. When the time of game came, I was leaving for it, but I don't recall if my friend was going. He seemed so immersed in studying strategy.
