What a difference an opponent makes

What a difference an opponent makes. In the hand below (which was one of my first ones of the night, by the way). I couldn't wait to get it all in.

He was a 89/56/3.4 guy over 37 hands.

Of course, it didn't actually turn out the way that I wanted it to. The good news is that I got my stack back and more a few hands later when I hit a flush on the river and he hit a straight and he called the huge overbet. Sometimes, I really love No limit (as opposed to Pot Limit). I'll stick with PL though.

Now, on the other hand, I played the below hand with a good player.

He is a 14/6/3.4 over 9.6K hands.

Now, this hand, I'm not so eager to stick it in. His range here has to be pretty tight when he fires a second bullet. What do you do? Also give me your thoughts on preflop. Obviously, I could have re-reaised; but I often opt with calling with position.

Have a nice day?
