The decision to semi-bluff has the next highest priority
(meaning if we do not bet or call based on EHS' we
consider semi-bluffing). If we are
faced with 0 bets and have a high enough potential to call both a bet
and a raise, we will open the betting ourselves.
If none of the other players bet or raise we will
continue to bet in subsequent rounds even without sufficient
potential (continuing to represent a strong hand while there is
a reasonable chance of winning the pot immediately).
Semi-bluffing is used when
Bluffing in this manner has a positive side effect by contributing to deception. If Loki never bluffed the human opposition would recognize this after a few showdowns and would quickly adapt, folding when faced with a bet or raise (lowering winnings). In fact, since Loki bluffs infrequently, the more experienced players on IRC often detect and exploit this predictable pattern.
