Blackjack SCOREs True Count Recalculation
often should we recalculate True Counts?
If we are using a true-counted strategy, we obviously need to recalculate
the true count before each bet. But do we need to recalculate it
every time we use it? Four sets of sims are displayed here. The
red area indicates the SCOREs assuming we only recalculate the TC
at the start of the round and then use that count for all playing
decisions as well as betting. Green provides results if we also
recalculate before making an insurance bet after we have
seen the other players' cards. This number would also be used for
playing decisions. Blue indicates the gain from recalculating the
TC once before playing your hand taking into account the other players'
hands. In these sims, we sit at third base, so all other players
have completed their hands. Finally cyan indicates the gain from
recalculation when needed after every hit. These sims use 100+ indexes
which increases the effect of always recalculating. The player will
need to determine whether the added gain is worth the added effort
during the play of hands. This chart indicates that a beginner can
start by just recalculating at the start of rounds and then calculate
more often when more experienced.
Note: These sims have four players. The number of players will
also clearly affect the gains.
As is usually the case, the single-deck results are very different.
Where there was little gain from constant recalculation in the shoe
game above, the single-deck game sees a great deal of improvement.
Again this is due to the increased importance of playing efficiency
in single-deck games and the greater volatility of counts due to
the small number of remaining cards. The single player sims were
three-player sims. More players would increase the blue gain somewhat.
Note: In all sims on other pages, the true count is always recalculated
for every decision.
