Is this a good spot to bluff? At the time I considered that he shouldn't have too much value in this spot and that he wouldn't be able to do anything against my aggression, but the more I think about it I think I chose the wrong spot to do this. They're going to have far more fives in their range than I have in mine, and it's probably better to just take showdown value with my ace high, as I'm likely way ahead of the SB's range.
Thoughts? And if I have chosen the wrong spot, what range should I use for this situation?
