Ruy Lopez, B + R vs N + R endgame

I'm happy with this game for a couple of reasons, but mostly from a psychological standpoint.

First off, the opponent was rated 1090 going into the game.  I definitely thought it was going to be a cakewalk.  This is often a problem for me, turning off my brain because I think for some reason that the game is won.  This happened on Monday in a game that saw me lose on a cheapo at the end after I had suffered on the defensive and then turned the game around and had it won.

However, in this game, despite going into it convinced it would be easy, I kept my wits about me.  For instance, 11. Be3 appeared to me at first glance to drop the e-pawn.  It has happened to me in the past that I would just say "this person is rated 1090, of course they just dropped a pawn for nothing, just grab it and begin the domination."  However, for whatever reason I actually said to myself "This is the kind of place where you get yourself into trouble if you're not careful." and I started calculating what would happen, and fairly quickly I noticed and/or remembered a trick from one of my first slow league games and I looked at Bd5 and saw that it wins a knight for the pawn.

The other thing is that due to my expectations, I started to get a bit frustrated that they were giving me a good game.  When I went down a pawn, I was actually a little upset thinking "If they keep playing like this, a pawn is certainly enough for them to win, and I will be quite upset if I lose this game." However, I kept myself together and just did my best and they started to go wrong with the queenside pawn pushes allowing me to get back my pawn, and then win one, and push on for victory.

So, basically I just feel that I avoided some emotional pitfalls that I have been prone to in the past and maintained both my mental alertness and my toughness.  Just one game, but it feels like progress to me.

As far as the game goes, just one feature seemed particularly interesting to me and that was the way the bishop and the knight opposed each other.  In some ways, after the queen trade, both pieces were a bit trapped. Her knight was a bit locked into protecting the d4 pawn, which couldn't move due to the b2 pawn (and later the rook), but on the other hand, the d4 pawn and the knight took away any useful plan for the bishop.
