Hi there FlopStraightAndFlush good evening, how you doing? Thank you very much for sharing your hand with the CardsChat community!
The flop is missing one card okay? Before thinking the river action, think about your preflop action:
I don't love calling too much from the Big Blind with dominated aces. (I don't love calling from the BB with almost anything). In a scenario like this, if I call, I am just calling to flop a monster: a flush, two pair, a trips, etc. We are not going to flop monsters many times, so I believe that versus CO opener and BTN caller it is a very easy Squeeze or Fold scenario. As it was a mini-raise you can make your Squeeze something like 4x or 4.5x.
By Squeezing CO and BTN here with a very strong hand (A7s) you can win the pot in two ways:
1) Preflop: Everybody folds and you collect the dead money, which is lovely and awesome!
2) Postflop: You can represent a stronger range such as AK, AQ, AJ, AT, KQ, KJ, KT, QJ, even AA, KK, all the pocket pairs, etc sometimes, because when villain in position calls it will almost never have these combos, so by 3betting preflop we take more initiative to steal the pot postflop because we can represent a stronger range.
In the flop you had the flush nuts or the flush-draw? (The flop is missing one card)
A) If you had the flush-draw this is a very weak raise. We are not raising 100% of our flush-draws or we are busted! It will become very easy to bluff us everytime we miss turn and river, and when we hit we will (almost) never be paid.
B) If you had the flush nuts it is a weak raise. If you flop a flush nuts in a situation with a monotone flop and check-raise flop, you gotta be very sure that Villain is gonna call you with worse flushes, straights, sets or whatever. Otherwise you are turning the nuts into a bluff.
In the turn you cannot represent anything right now. If you have a set and double barrels turns you will make all the flush draws, straight draws, gutters, and a lot of pairs fold, they should not continue here. When you bet you still have the missed flush draw in your range, that missed and decided to bluff any turn, which makes the call easy for CO's Villain.
In the river you check and you don't have many strongs hands right now. Your sets could be checking turn, your two pair also, you don't have AK, AQ, AJ, KQ, AA, KK, QQ, JJ because you would have made a 3bet preflop most of times, and it's nasty. I like to check this river when I have a very strong value hand and I know Villain will bluff me because of the missing draws and then I would have either an easy call or an easy raise.
The way you started the story was strange. IMO, if you should bet river again, trying to represent a set or two pair, but even so it is very strange.
