The rec who gives unsolicited advice to other players about their hands is not a good player. He just thinks he is. His own game is full of the exact leaks he's critiquing in others.

Why they do it

Players who coach the table at $1/$2 are almost always losing players with confident opinions. They've watched enough poker on TV to have a vocabulary but not enough experience to apply it correctly. Their own tendencies - usually calling too wide and not folding enough - are the exact opposite of what they're preaching.

The adjustment

Play straightforward against them. They're beatable with fundamentals. Don't let their confident talk make you think they have a real game behind it.

What it's worth

The loudest guy at the table giving the most advice is usually one of the softest spots in the game. Don't let the noise fool you.
