I like to play the Marshall Attack as Black against the Ruy. Given the well travelled path of opening theory here I know the line to about move 15. I hope to learn more and be able to win occasionally and force a draw when I need to. It's an attacking line but against proper play most likely a draw.
Here against Sliuszicht 1697 on Playchess. BTM. ( I played Bd7 and eventually lost)
I would like to play the thematic F5. Charge ! Fight to Open lines .
f4! f5, Bxf5 gxf5, Rook Lift Re6 and black is better after the bishop sac.
