XVP - But not X advantage play

Two other things you may need to check. If it is the Williams game no double on nine or after splits (no resplits either). That might be the diff between +0.1% and -0.11%

My problem is this: I am looking for a blackjack game analyzer and
simulator that can handle this game. I have not been able to find one as
yet. The game MAY have a VERY slight player advantage if a composition
dependent strategy is used. The Wizard of Odds site implies this when I use
the BJ calculator there.

I would welcome any help to find a suitable software program where I could
run simulations of perfect play for 2, 3, 4, and 5 cards taking into
account the dealer's up card as well as any cards already seen in the hand.

I'll even post the rules:

Single deck shuffled after each hand (only 1 player per hand. This game is
on a machine)
Dealer stands on all 17
Dealer has a hole card
Tied Blackjacks are a push
Double 9, 10, 11 only
No Double after split
Split only once
Re-Hit split Aces
BJ pays 3:2
6 Card automatic winner for player but not dealer
No insurance
No surrender

My blackjack program that can analyze this game.

I get a player edge of 0.108% if the 6 card automatic win only applies
when the dealer does not have a natural, and a player edge of 0.12776%
if the 6 card win applies even if the dealer has a natural. These numbers
assume a composition dependent strategy. There are about 1400 exceptions
to basic strategy, I'm sure many of them come about because of the 6 card
automatic win. This is such a large number of special cases that it would
probably be quite difficult to memorize them all.

The rules I listed below are accurate. You can double on 9,10, and 11 only.
You cannot double after a split. You can split to 2 hands max. You can
re-hit split aces. It is not a Williams game.
