    3 way to 2 way conversion??
    if I am given these odds, does anyone know a website with a calculator or a formula to remove the draw option and provide 2 way odds?? Odds provided are no vig odds by the way.

    +102 (1)
    +342 (X)
    +259 (2)

    Thanks for any help

    +102 converted to implied prob = 49.5
    +259 converted to implied prob = 27.8

    49.50% and 27.80% = 77.3%, add percentages together, removing the tie, to get the total percentage.

    77.3/100 = .773

    49.50/.773 = 64.03%
    27.8%/.773 = 35.97%
    Divide each raw percentage by conversion to get back to 100%
    64.03% and 35.97%= 100%

      So I’m assuming 49.5 and 27.8 are the percentages of (1) and (2) so 77.3 is them added together. How did you get the final of 64.03 and 35.97? Sorry, I’m confused

          I would always go with a 3-way, assuming your partner is ok with it too.

            I'm not disagreeing with what has been posted by @Waterstpub87, but I suspect the question is more about the win probability for either side in extra time and a possible penalty shoot-out. If the: +102 (1); +342 (X); +259 (2) line is for a cup tie with no replay and winner progresses implications then the outright line on the tie isn't going to be -178 (1); +178 (2) based on the 64.03% and 35.97% win probabilities. Essentially extra-time is is going to be closer to a +/-100 line with the original favourite a now smaller favourite. I did reverse-engineer a conversion formula for extra-time draw values 6 or 7 years ago that recreated sportsbook 'to progress' lines to within 0.1%, but it's really only useful for World Cup/Euros tournament playoffs.

            Edit: on the other hand if you're pricing up a 90 minute league match with 'draw no bet' then +/-178 is absolutely correct.
