    Thanks for bearing with me Don, I appreciate it! I look forward to hearing from Cac as well.

    Yes this definitely helps. Would love to get my hands on this book. From what you wrote above, Canjar's paper seems to agree with Grosjean's concept of LOWERING the index (by varying amounts, depending on fraction of BR originally bet) when holding a strong hand such as 10,10, which would be in contrast to Cac's original RA results for 10,10 found in the "Best of the Masters" section of the boards.

    Thanks again Don,

    Don!

    I've got your mail yesterday. Unfortunatelly, I'm abroad
    at present without any technical stuff handy. In any case,
    I do think that my article "Even money. Fundamentals and excerst from TOB"
    (just scroll down this page until reaching it) may add a little bit of more light, for BJ Crusader and Rukus.

    Sincerely yours

    Zf

    Zf, thank you very much for your reply despite being out of the country. However, scrolling down, I am not able to see a link or anything to your article. Am I missing something?

    Also, does anyone know if UNLV Reno is still selling a copy of the book Don mentioned for $59? I haven't seen it available anywhere else, but there is still an old-fashioned order form on the UNLV website...

    Thanks again,
    Rukus

    Apparently. It's less than halfway down my page.

    I actually don't see the link either. I'm not sure what special powers Don possesses that enable him to see it, but apparently they're ones you and I lack :-)

    I bought a copy from the Gambler's Book Shop in Las Vegas, but the website says they're out of stock. It might be worth calling (800-522-1777), though.

    Go back to the main "Theory and Math page" and then scroll down. It's about half a page down.

    Is that not what I said?? In any event, it's not a link; it's the original POST that Zenfighter made, and it's simply further down on this page.
