Heads Up Play

Try to focus on more reading the player.
Then start from that info build your game.

If the players is tight try be more agressive with weaker hands. ..if he is agressive try to reraise him or to be tight...

Be more aggressive heads up and dont just wait for good hands because that will take too long. Loosen up your play and play to your opponents weaknesses. In the sng's, you can stay tight at first and then loosen up but not as aggressive as heads up.
