who has the advantage on this one?
I've got KhKd
he has 8c4c the flop comes 3c8dJc after him going all in, me calling, and him catching a 4, we got in a futile argument on who had the advantage to win the hand after that flop. I'm not a math whiz, but by my calculations I think I'm at least a 55% to win... can anyone do the math for me? by the way this guy finished in the top 30 of the wsop this year.. |

exact calculation
P(Kings win) =
(8/45 * 0) + (2/45 * 2/44) + (3/45 * 7/44) + (1/45 * 9/44) + (24/45 * 30/44) + (6/45 * 34/44) + (1/45 * 36/44) = (4 + 21 + 9 + 720 + 204 + 36)/(45*44) = 994/1980 = .502 The long sum is a weighted average of the kings chances of winning, depending on the next card. In each term, in the first fraction, ie x/45, there are x possible turn cards that give the kings a y/44 chance of winning the hand. For example the 8 cards that have the kings drawing dead are the 8 clubs that don't pair the board. The two cards that give the kings two outs are the remaining eights, etc. I may have made a mistake or two, but it seems to match the sim data. |
