If you flop a straight, and it's the nuts, what % of the time do you have the best possible hand on the river?
For instance
- The board pairs a little over 1/3 of the time
- If the flop is rainbow a flush comes in about 4% I think?
- Front door flush is about 36%
- Higher straights are much more difficult. I think they are about 1/3, but Broadway straights are immune to this. 56 on a 478 flop is much more vulnerable than a 234 flop
In aggregate I think I've come close to the an answer (about 25%) by just putting in hands against straights multi-way, but does anyone have a way to get to a more precise answer?
