Three Heads-up Wins in A Row

Entered heads-up tables on PokerStars for $100 buy-in. Won three in a row, and it was too easy.

I was surprised that the opponents didn't understand heads-up play. Some errors these opponents made:

If you only raise when you have a premium hand, that is a mistake.
If you bet the minimum as a bluff on the flop every time, that is a mistake.
If you are going to fold to a pre-flop raise unless you have a big hand, that is a mistake.
If you are going to fold with rags pre-flop every time, that is a mistake.
If you never re-raise a pre-flop raise, that is a mistake.

You can't be predictable in heads-up play or you'll never win. While luck is always an element of poker, I think heads-up play may give a good player a bigger edge.
