Yeah, having a guy duck his head down (enter the snake) is the best way to lose a 3 man or especially 2 man tourney.
Keep guns up, head's up, and make smart small moves. Remember you can try crazy stuff 5 on 5 as you can win 4 on 5. You're not gonna win often 2 on 1, so you had better not be the team to lose the first player.
So lane like mad, be safe, make smart moves to spread the field, and wait for your chance.
