AK vs. AA or KK
I hold AK
Board reads AK2, suits unimportant. What is the likelihood my opponent holds AA or KK, assuming the following range of hands: 88-AA AKs-A8s AKo-AJo Suited connectors KQs-T9s |

Re: AK vs. AA or KK
I'll take a stab. First off, suits do matter in the number of ways to make AK suited. If the 2 A's and K's out are all differant suits there are no ways to make AK suited, if the A&K's known are only 2 suits (AsAhKhKs) then there are 2 ways to make AKs. I will assume 2 ways on AKs. So, the number of ways to make each hand given cards obsereved is as follows:
Pair 8's 6 Pair 9's 6 Pair 10's 6 pair J's 6 Pair Q's 6 Pair K's 1 Pair Aces 1 AK s 2 AQ s 2 AJ s 2 A10 s 2 A9 s 2 A8 s 2 AK o 4 AQ o 8 AJ o 8 KQ s 2 QJ s 4 J10 s 4 10 9 s 4 Total 78 AA 1.3% 77 to 1 KK 1.3% 77 to 1 |

Re: AK vs. AA or KK
I get the following:
88-QQ, 5 prs x 6 ways to hold each= 30 KK-AA, 2 prs x 1 way (only 2 A's, 2 K's left)= 2 AQs-A8s, 5 hands x 2 ways (only 2 A's)= 10 AK (suited or unsuited), 1 hand x 4 ways= 4 AQo-AJo, 2 hands x 8 ways= 16 KQs, 1 hand x 2 ways (only 2 K's)= 2 QJs-T9s, 3 hands x 4 ways= 12 Total ways to hold these hands= 76 Total ways to hold AA or KK= 2 P(AA or KK)= 2/76= .02632 or odds of 74:2, i.e. 37:1 against. [/ QUOTE ] You are correct I counted 6 AK's but there can be only 4. so 37 to 1 your opponent holds either AA or KK. |
