I think c/c is better than bet/call. What do you expect to call our bet here that doesn't beat us?

c/c allows the flush draw to bet at us if this was MP3. To be honest I am not so happy about the overcall but I think getting the odds you are getting you can call.

If I was playing I would probably have folded, thought about it, then wondered why I would have folded.

I would have been annoyed if the pot was lost because I folded a winner but I don't think it would have been a HUGE error.

I probably end up check/calling.
