Not a slow roll:
1) They both played for 10 HOURS (heads up), they were both visibly tired so reaction time may have been off.
2) Cynn did not have the nuts. So he had to take time to consider how many bluffs are in Miles range compared to value
hands. He was losing to full house if behind.
3) When you have been grinding a poker tournament for 10 days and a $3.8 MILLION dollar decision is on the line you can take as much time as you need to make that final call. For the most part they both were playing pretty quickly during heads up.
