I'm often in trouble with a lot of people who are like 40/35 and very agressive postflop.
They bet very often all sort of sizing don't fold vs raise and do a lot of strange things.

When you have a big hand it's great.
But because most of the times we have nothing I found difficult in many spot to fight correctly.

When you have 2nd pair type hand for example how do you react ?
Because I don't want to raise and make a big pot but at the same time by just calling often the board become uggly and villain have an easy life.

What make you choose between raising for value/protection or just calling to induce the bluff ?
