How shall I proccede? I whish to protect my hand but it is expensive to protect my hand and I am not sure that I have the best hand.....

Please comment the other streets too. The miniraise preflop was probably not so good [img]/images/graemlins/smile.gif[/img]

I will post the rest of the hand later. I think that I will need some comments there too [img]/images/graemlins/crazy.gif[/img]...

Thanks!
