Stalked by a Hand Splitter
does splitting to multi-hands affect others?
Some card counters play one hand at negative counts but then spread
to two or more hands at positive counts. But, what happens when
someone else does this at your table? This chart is very much like
that on the previous page. The first sim had two players: a basic
strategy player in seat one and a Hi-Lo card counter in seat two.
The second sim was the same, but a third player plays one hand at
true counts of zero and below, two hands at TC +1 and three hands
at TCs +2 and above. We are interested in the effect on the Hi-Lo
player in seat two. The chart displays the win rate by true count
for the seat two Hi-Lo player in each sim. The red area displays
the win rate for each true count for the Hi-Lo player at the first
table. The green area shows the win rate for the same player, only
at a table where the multi-hand player plays. As on the previous
page, we can see that at the higher counts, where we win money,
our winnings are reduced by the new player as he is stealing some
of the good cards. Overall, the Hi-Lo player's edge drops from 1.37%
to 1.15% worse than the effect of a backcounter.
The Blackjack basic strategy player is not charted here but is
also impacted. For the basic strategy player, the house edge increased
from .38% to .48%.
did the lost winnings go?
We have seen that the frequency of positive true counts that you
experience will decrease when a back-counter is present. This chart
details that effect. The red line in this chart is taken directly
from the red line on chart two on the previous page. At the negative
counts, the Hi-Lo player plays about the same number of hands whether
or not a backcounter is present. But when the counter is haunting
the table, only 80% as many high true counts are enjoyed. Now we
add a green line to show the effect on the Hi-Lo player of another
player splitting to two and then three hands. The hands played at
a positive count are more severely reduced.
