That tip is bad. Raising 2-3 BB fromt here means if you get one other called your giving the blinds huge amount of equity to call with maringal hands preflop.

And also i disagree with calling behind on the turn. If you call you should slow down a river bet. If he bluffs againt hen great, if ouve got a read do whatever you would do. But calling this TINY turn bet (Which is 20% of the pot btw) is better than raising/folding
