A straightforward and uncreative player in late position reraises you to $40. Suppose you are playing $1/$3 no-limit hold'em and before the flop, you raise to $12 in early position with a pair of jacks. One of the words that you hear most frequently now is 'combinations' or 'combos.' Once you accept the concept of an opponent (or yourself) having a range of hands, the next interesting question is, 'Well, how many hands are in that range?' The way you answer that is to figure out how many 'combinations' there are of the hands that make up the presumed range.
I mean, when I was playing limit hold'em in San Jose 25 years ago, had you said, 'minimum defense frequency,' they'd have thought you were talking about the 49ers. In the last couple of years, as theoretical understanding of poker has galloped forward, an entire new vocabulary has emerged.
