Why would you not raise the turn? You have the nuts but it's vulnerable to 1/2 the deck on the river.

You know the state of mind I was in last night. If the river could have possibly hit BOTH flushes, I thought it would have.

Have I rubbed off on you? You have to get some more money in on the turn on this one. DO NOT PAY OFF ANYTHING ON THE RIVER.

Getting one of the draws to fold on turn brings your equity up from %50 to %80.

You are in position , they must be braindead to bluff you on river if a scared card comes and you can always check behind.
