Villain's 3bet range looks pretty solid from those 2 hands that were mentioned.

With KQs,i wont really open it UTG+1.If i do,and i get 3bet from Villain.I would certainly call this purely because our hand has a huge equity(opportunities for straight n flushes) when we flop hard,and we're deep.Although we're oop,being deep compensates for it sometimes

As played with AK hand,i'll fold pf if you are not able to play it properly postflop.I dont mind raise/folding here.If you c/c the flop,i think you should be calling the turn-its an obvious blank.
