Playing Checkers and Chess
After a player brought it in and another player completed, Josh Arieh called and Phil Ivey put in two bets. The bring-in and completer both folded while Arieh made the call. The two-time bracelet winner proceeded to check-call a bet on the turn before check-folding on fifth.
Arieh: (x-x) / 


Ivey: (x-x) / 


Arieh may have identified the problem as he pointed out on Twitter:
