Ought versus Is
I always thought that was a pretty obvious characteristic of the how-to genre.
Which is why I was surprised when I saw the thread on 2+2 that started out
If you take a look at Harrington on Hold 'Em Volume 1, published just before 2005, you'll notice that in it Dan says "I like my continuation bets to be about half the size of the pot" and "...half-pot is an ideal size...". He goes on to say you can vary your c-bets from around 40% pot on the low side (for dryer flops) to 70% pot on the high side (for the very, very drawy flops). He appeared to believe half the pot was enough to deny proper odds even on something like a J82hh boardEven more amazing than the question, it that none of the answers pointed out the question was based on a false premise, they all took it was a real question and tried to rationalize an answer.
It seems to me the average size of a continuation bet has gradually gotten larger and larger since then.
The right answer was simply that the norm was never a half-pot bet. If used to be full-pot size bet, anthing smaller was considered an underbet. Since Chris Ferguson popularized the idea of a half-pot sized bet the typical bets have gotten smaller, not bigger.
