I got my start by watching my cousin play live on a video call, he'd explain why he was folding or raising in real time which made the logic click way faster than reading any guide. Once I tried a few hands myself on a micro stakes table I realized the actual betting flow is much simpler than it looks once you get past the initial confusion of the hand rankings.
Messi lifting that trophy would completely overshadow any ref talk for me, honestly. It is like the iconic photo of him with the cup will be what people actually remember, not the VAR arguments from a group stage match.
Argentina always seem to get talked up before it all starts but then the actual tournament rolls around and someone like Fraance or Brazil just looks way more settled across the whole pitch.
