I've played GMs before in simuls. They don't lose or even draw much. You'll have to play as solidly as you can. Don't try anything funny.
I thought I'd play the Scandinavian against Arthur Bisguier in a simul when he was long past his prime. He dismantled me.
Hi guys! I'm really lucky to be able to play in a simul against John Nunn! Do you have any tips for escaping with a draw?
I'm sure playing him will be a valuable experience to boost my confidence and playing ability.
