Is this the proper place to post a question/comment on the Blackjack Card Counting Game on Wizard of Odds? If so, it looks to me as if there are some bugs in the software when warning on strategy errors. I'm not sure if it applies any index plays based on the true count, but for sure telling me that hitting a 13 against an 8 when the count is +1 can't be good advice. There are other obvious errors, and at some point the "analyze hands" percentages or odds are easily wrong. I've even seen where ALL the options are reported with the same result - all zeros.

I'd like to say that it seems like the dealer gets far too many blackjacks, even on a negative count. But that's probably providing the same level of real world outcomes that we all see and bitch about all the time. But still...

Hitting 13 vs. 8 is basic strategy. There isn't even an index play for it in the I18.

The advice offered in the game is always based on the perfect analysis considering the current state of the shoe at that time.

There are, however, times when communications glitches occur. Behind the scenes, there is a chain of communications that occurs to perform the analysis. If something goes wrong in this chain of communications, then the analysis will show all zeroes or will say "Analysis error". If you get non-zero results, you can be sure it is showing the correct analysis.

For sure, that is correct advice.

I misstated the earlier example - but whatever it was, it was wrong.

Here's one I have on my screen right now: Dealer shows a 2, player has 2-3. True count is -1. The game says: Hitting is not the best play. Analysis says: Surrender: -0.50000, Stand: +0.639719, Hit: -0.642205.

So I did not take the advice, and insisted on hitting. I got a 9, so my hand is now 14 against the dealer 2. I select stand and the games says: Standing is not the best play. Analysis says: Stand: -0.336923 Hit = 0.318846.

I have also seen the game reporting an analysis where all the options are 0.000000.

I'm using the game to hone my skills with count and I18 variations. So "false-positive" strategy errors are annoying and distracting. They are occurring often enough and in such obvious situations that I can't think I am the first person to notice and report them. In this case I haven't played three shoes and see these errors.

Perhaps some registers are not getting cleared when the end of the shoe is reached?

Sorry to be a pest, but...

How can a running count of +5 and "decks remaining" of 1.7 yield a true count of +1? 5 divided by 1.7 = 2.94.

I don't know if the running count or decks remaining is accurate, as I am not keeping the count in my head and don't have a shoe or a discard rack to use as a guide, but I assume that what the program displays is in fact the true state of things. Even with a "by-eye" approximation that you would have to use in the field, TC 5 divided by 2 decks left = 2.5.

Are there other simulation packages out there, even available for sale as opposed to this free one?

Do you have a screenshot?

I'm not sure how to do a screenshot. If I do <ctrl>PrtScrn I get my whole desktop display. I can then drop that into Word and crop away the parts of the desktop that aren't the window of the simulator, but I can't figure out how to get that into this reply. Do I attach a file somehow? I have seen images from people's phones here, but not screenshots. I'd take a picture of the screen, but then there's some skill in getting that into this reply that must be just as foreign to me. I'll keep trying - but give me some clues? Thanks.

Never mind. I did a little searching here and found some directions. Here's an example where the running count is +7 with 2.7 decks left. 7 / 2.7 = 2.6. Even assuming a by-eye approximation as you would be doing in real time, a true count of 7 divided by 3 decks remaining is at least 2. I did not keep track myself to see if the true count is correct, and of the cards played to see if "decks left" was correct. I adjusted the rules to 6deck, S17 but other than that all the rules are the default. I think I see the counts adjust as individual cards are played, but in this case the cards in this round net to a running count of 0, so nothing has changed as of the start of dealing this round.

Here's an example of what I think is an incorrect "best play". Stand a 16 against a dealer 8? This can't be an index play far down the list from the I18. A TC of -3 would seem to me, if anything, maybe say to HIT the sixteen INSTEAD of stand, since there are more low cards out there, and therefore a better chance of not busting. Oh yeah -- the TC is wrong here as well -- running count of -12 decks left of 3.1 - TC = -3.87. Using the by-eye real-world method: -12 / 3 = -4.

For some reason the IMG code does not work here like it did in my previous post. So here's the link:

I added .jpg to your IMG and it posted. No idea why it needed that, but it worked.
