I'd recommend to play for a complicated position and try to find a continuation with a sting in the end. With luck it'll be crippling to some degree. That's the best I can think up for you.
Below is Jude Acers playing 117, and I was among them. I lost, which was unfortunate because he wasn't playing all that brilliantly. He was just a 2400 USCF .
You can't see me but you can see my board on the line of tables on the right hand side, vinyl board, second board up from the end. I am screwing up a Vienna Game and we are just a few moves in.


My Question is about Simultaneous Exhibition games. How do you play, or improve your chances of beating the Grandmaster? (or IM, etc). What have you done? Who have you played in a simul?
I've only played a couple simul games. Online vs Michael Brooks(USA) when he as "only an IM" rated over 2500. I think he is a GM now. But he crushed me mercilessly. Not only that, but I could FEEL the pressure coming across the board and thru my monitor~! Until my game went Splat.
So what should I do online for a simul? Or especially an OTB simul played live? Is it different?
Some only play WT pieces while others alternate colors. Some will play with clocks. It seems like getting WT against him and having clocks may be an advantage?
