A storm is brewing in the poker world, and it just gathered more force. There’s been a simmering feud between Doug Polk and Daniel Negreanu for a while, but it may have just escalated after Polk recently referred to the Hall of Famer as an ‘embarrassment to poker’ during a live YouTube podcast.

The poker pro’s comments came during a joint two-hour conversation with fellow podcaster Joe Ingram, another well-known high roller in the poker world. While the podcasts usually deal with Polk’s involvement in cryptocurrency, he and Ingram focused more on poker, including the changes in the poker ecosystem and the alleged cheating and collusion on Americas Cardroom (ACR).

Ingram has spent a significant deal of time this past week discussing the action on ACR, a popular U.S.-facing poker site. He’s convinced that multiple bots are being used on the site, despite not having any evidence to back up his claims. He has also suggested that ACR is allowing previously-banned accounts to be reactivated, and that there is substantial collusion occurring on the site.

When the topic turned to Daniel ‘KidPoker’ Negreanu, however, things got a little more interesting.
