Not if you think you are against a tight player.

He looks like he is willing to go all in on this hand - as he has now raised you 2x.

Your only beating a bluff or a draw. Folding here left you with 3000 chips - plenty enough in heads up to hit your hand.

If you called all in - and he had the A - you basically lost as you'd have very few chips left.
