easy, ill give you how to do it
Mr.Genius is play Aronian on Board A and Bareev on Board B
1)Wait for Aronian to move (as white), aronian plays 1.d4
2)Go to board B and play 1.d4 against bareev
3)Bareev responds with 1..nf6
4)Go to aronian and play 1..nf6 in response to his 1.d4
essentially theyre playing each other, ad you will either win one and lose one, or draw both.
Harry Anderson

So Harry Anderson, actor from the TV show "Night Court" back in the 80's, claimed he could win as many games as he lost in a simul, even against the best players in the world. Thoughts?
