Small Stakes No-Limit Hold'em

For various reasons I've recently been exploring cash head's up play. I enjoy the constant decision making and the opportunity to figure our the playing style of one opponent, rather than a table-full of opponents. Because of the large number of decisions my opponent is required to make a playing style generally emerges fairly quicly.  True, some are tricky. The better ones try to play a style that is more difficult to exploit. But, for most opponents a style quickly emerges that can be countered.

I guess I'm looking for some serious feedback on how well the concepts of SSNLHE translate to the HU game…. especially the cash game. (In tournment play the blinds are often so high the head's up aspect of the game becomes more of an exercise in ICM knowledge).

There is not much on the market in terms of books devoted to HU cash. I was wondering if anyone has some serious thoughts about this book and it's use as a "primer" for head's up matches.

Thanks… Terry
