you get all in with AQ here preflop? no wonder you are running bad. you are much better by far to just calland play teh flop unless you know he wil lfold. thefact is that when you make this play at this level 9 times out of ten a guy holding AK knows he is good against a weaker ace or at worst against a small pair and he will see all five cards with a larger stack.

even if this guy has been rasing with garbage for the last 10 minutes?

any more suggestions please?

why do you make any moves when your have decent chips?

raise preflop and don't challenge the big stack.
