The reason smaller bets are more ideal on boards like this (from a strategic standpoint) is that equities tend to be very non-smooth. Ie. most hands will either have a ton of equity or very little equity. Another way of saying it is most hands are either "way ahead or way behind" with little opportunity to improve (not many draws).

In this case, a smaller bet-size is the most difficult to handle given that most of the range facing the bet would prefer either a much bigger size, or no bet at all (to make it easier to defend the entire range). Thus, it's typically the most difficult strategy to counter.

Why does most of the range facing the bet prefer a much bigger size ? Is there somewhere I can find an explanation of this ?
