On the flop I regard his minraise as a standard bluff so I call not wanting to blow him away just yet. On the turn I get raised again so I start to worry about my kicker. Would you just push over and accept that if you are outkicked it's just bad luck? On the river most of my kicker worries seem to have disappeared, what should I do? Thanks
