1- I check behind and see what card/action comes from SB.

2- Hero is all over that shit

3- Hero raises more preflop. Why did you check the turn? If you wanted some action you have it, so go with it.

4- Again raises more preflop. With your check on the turn he may be trying to buy the pot. With the K to the flush here I say fuck it a lot and gamble with a shove.

5- OMG easy call

6- You checked the turn. To me that says something like AK that missed. I call this river more often then not. I also don't check the turn in the first place though.

7- Turn bet was weeeeeeeeeeeeeeeeeak. I sometimes throw a blocking bet on the river here. If CO had something like 78 your turn size allowed him to come along. His bet looks more like for value then as a bluff.
