Calling down with A high!

Well the other day i made a great read in live poker and called my m8 joe down after he bet the turn and the river with just ace high, pleased me a lot. Before i wouldnt usually do that even if i knew they had nothing.

Anyway just now i did exactly the same playing 6 handed on pokerstars for ALL of my bankroll!!!

Bankroll: $100
