Hi Mike!
I’m a young player looking to elevate my game as well. I would have made the same move you did. Its awfully tough to fold the 4th best hand in poker; especially when you do not know how the villain plays (I’m assuming you don’t have any prior experience with this player). I had nearly an identical situation in my last tournament, except I called with AcKc. It’s just the luck of the cards sometimes. Good luck at the tables!
