I thought this was an interesting game in my new Ruy Lopez experiments. I think it was an example of analysis errors causing me to enter positions that I thought were good for me but obviously not.

I dunno about 9. Bg5. Maybe the bishop was better placed on e3, which would make it easier to develop my knight without having to worry about d4.
Analysis mistake No. 1: I didn't think he'd want to play 13. ... hxg5 because eventually he's going to have to castle and that weakens his king. But apparently he didn't have to castle and he used that file to good effect.
On 15. Re1, I kept thinking there had to be something in the center for me with his king uncastled, so long as I could survive an attack on h2. But of course, there's another "focal point" (as Vukovic described them in Art of Attack) on f2, and I can't defend them both so I'm toast.
I think it's interesting to me that chess players seem to have wildly varying temperaments with their analysis. I tend to overestimate my positions and be very optimistic. I always think "This *has* to be good for me" even when objectively it isn't. There's a player at my club who is the biggest Eeyore I've ever seen. He is passive and fears monsters under the bed on every move. He's constantly convinced his opponents, even when they are down significant material and about to resign, are about to unleash some flurry of tactical dominance on him.
