Heads Up SNGs...

[Kurn]

Look at where your edge comes from in cash games or full-ring tourneys. #1 factor is your opponents play too many hands. Well, that's out the window in a HU SNG because the biggest mistake HU in a tourney is folding too often.

Plus you also must play more hands past the flop or you'll get run over.

3rd, the blinds keep going up, so you will regularly get forced into playing 52:48 for all your chips.

In the end, your edge is solely on your ability to bully/manipulate your opponent as opposed to that being a small part of your arsenal vs a full table.

Luck (as in who gets what cards) is a much bigger factor HU. You are much more at the mercy of the deck when HU in a tourney. HU cash games are different simply because the stack size vs the blinds remains high.
