Saw My First AP (maybe)!?

20 to 1 Spread,

"He kept hitting his 16 vs 10 in positive counts."

Even with a weak spread, it is wrong to auto-hit that hand.
The actual cost is rather reasonable, unlike what you said.
That does not make this unwavering play appropriate.
One of the easiest way a pit critter has to sniff us out is
to observe suspected card counters altering their play on
close decisions (with ZERO indices). A ploppy will not vary
how they play their 16 vs. 10. If you have a decent spread,
neither should you. STAND, muttering "I never hit that crap."

A closely related issue is that it is 100% WRONG to always
hit 16 vs. 10 with Counter Basic Strategy. ("CBS"), where
you alway STAND on 16 vs. 10.
CBS was created for those who want to primarily use bet-sizing
as his strategy, and thus uses a "Basic" Strategy that will do the
best via a weighted average (summing results across TC's), e.g.
Standing (ALWAYS) on 16 vs. 10 costs virtually nothing [if the bet
spread is reasonable]. Ditto for doubling 9 vs 2. etc.

IF one were a super counter, and it was a pitch game, and your TC was high [to a Level One player]
but was actually "counterfeit" -- due to a high density of remaining 5's and 4's (and very depleted
2's, 3's, and 7's) it would be correct to hit.

NOTE: The late great Dr. Griffin stated that more accurate than any counting system [for this play]
is knowledge of whether there are more or less 6's than 5's remaining to be played; although the
reference was for a single deck, it would hold true in a multi-decks game when the discrepancy was
more than slight, with TC's not from from ZERO.
