Those hands, A-10, A-9 get players into a lot of trouble. But, the difference between KJs and KJo is a pretty good difference. Not enough to change whether or not you call a bet in which somebody is allin, but in a less-than-substantial preflop bet I'd say it is important. Assume you're a big dog, KJ vs. AA.
Look at these numbers and how you fare preflop. Bringing the flop in makes this so much more complicated because of all the possible suit combinations on the flop. I did the odds through Cardplayer.com's odds calculator.
Offsuit(Assuming his AandA isnt the same suit as your KandJ)
85.9-14.1
Offsuit(His aces cover your K and J in their respective suits)
87.5-12.5
Suited(One of his aces is your suit)
83.2-16.8
Suited(He doesn't have an ace of the same suit as your KJ)
81.9-18.1
+/- 4%. I stress again, everything could easily change after the flop. This is just preflop. These hands increase tremendously in headsup and shorthanded play, but this is just an example of all the hands stacked up against pocket aces.  |
