Well, what happened from that point onward wasn't even a match. It was basically an adult spanking a newborn child. The other side had absolutely no way of defending himself. Not only that, the moment the terrain was generated, Roan knew what the rigged part of the board meant for Olly's strategy. For Roan, Olly was basically telling him exactly what he intended to do.
"This..." Olly looked at the outcome of the game with his eyes wide open. He hadn't lost yet, but he couldn't see a way out at all. "How can that be?" His 'king' or the piece with the same level of power was completely surrounded. The funny part was that Roan purposely left that piece alive on the board as he focused on wiping out all the rest.
What did Roan want to show with that? Well, everyone could tell. He simply wanted to show the difference between Olly and himself. "That's about it. I can finish it, or you can surrender. Which one do you want?"
