You make the call

Here is the scenario. Semifinal round. 4 players per bracket with top two advancing to the finals. You are player A and currently have 5 wins with one game left to play. You have already clinched a spot in the finals. Players B, C, D have split their games and are tied for second place. The only game left is with player B. if you win the game then all 4 players move to the finals because the other three players have the same score and same tiebreak. If you purposely throw a draw to player B, then you only allow player B to move on, thus increasing your odds to win in the finals. The downside is you screw players C and D out of a chance for a medal. What would you do in this scenario?

If C and D are better player, it would be better to draw with B and save energy for final, else try to win B in present round.
