More information, please
If you have AA and isolated preflop so that you are headsup...
Is there ever a reason NOT to raise a river bet on this board?
K67KK
99 should pay?
Any 6 or 7 ?
Quads is the only concern....
Hi there Poker_Mike, thank you for posting your hand. However, the way you explain does not allow us to properly analyse your hand:
A) Do you have AA from which position?
B) "isolated" means a single raised pot, 3bet pot or 4bet pot?
C) Villain is in position over me or do I have position over villain?
D) Do I have any stats or notes over this villain?
E) How was my image at the table when the action happened?
F) How was the Villain's image at the table when the action happened?
G) Stack sizes of Villain and Hero = ?
H) How did both Villain and Hero played the Flop?
I) How did both Villain and Hero played the Turn?
J) How did both Villain and Hero played the River?
I don't know any of these items above, but according to your question I will try my very best:
"Is there ever a reason NOT to raise a river bet on this board?
K67KK"
There are several reasons for not raise this river:
1) You are playing 200 NLHE, which means that for the most "fishy" your opponent is, it would be most of times a very decent player/fish/recreational one. If I were playing at the micros I know for sure that many players would go all in in this river with 22+, any 6 or 7 no matter the stack sizes. At 200 NLHE I am not so sure, because the ammount of recreational players is minimal.
2) Another reason is if you are 300 blinds deep and Villain is 300 bb when the hand began. Do you really believe that at 200 NLHE a fish would be putting 300 bb (USD 600) on the table with 22+ (Any pair here completes a Full House, any 6, any 7) If the answer is yes, okay easy call/raise.
Depending on how big my stack is in relation to the pot versus villain stack versus board configuration I would simply call this river with my value hand, that can be the nuts in most of cases here, but it is not a few chunk of times. I would re-raise this river or jam upon it if I am close to 100 blinds deep and I have river information/showdown history with the player that it might be trying to
bluff me with 22+ or any 6 or 7.
If we are in a 3bet pot the situation gets very dirty. By the same token that the board blocks 75% of combinations of combos of kings that the opponent could have, if we consider some types of players (Average Regulars, Good Regulars, even Breakeven Regulars, NIT's TAG's LAG's), we know that in 3bet/4bet pots they will have a lot of Kx in their ranges.
We know that some kind of players never re-raise river, unless when they have the cold stone nuts. Against a player like this I would fold to some ludicrous jam in the river, but I could call in a medium frequency, for exploitation to avoid to be bluffed in a lot of rivers with bluffs or worse
hands on V's range.
I would do such action of calling a jam or re-raising river with a very strong value hand with a regular when I have a sample of hands played of at least 2 K (two thousand) hands.
