DERLD

Many people have struggled to beat Andrew Tang. I recently managed to draw to him in a DERLD, also known as the Delayed Exchanged Ruy Lopez Differed. The DERLD is a solid line that gives up the bishop pair, but also gives good compensation for the bishop pair. While it isn't great as a main weapon, it can be used occasionally. It definitely surprised Andrew Tang and he wasn't able to create any advantage and had to concede the draw.
