I had been tight so far, but not too tight. Mostly taking down pots preflop, raise/folding one time preflop and taking a flip on the bubble with AK &gt; QQ.
Villains has been playing very tight so far, something around 5/2 or so, but I did not see him cold calling raies yet.

So do I have to call here or not? And as a side question: Would we call without our gutshot?

/edit: Forgot to mention, that we are itm.
