O_o What does Fritz actually tell you about the game? What would have been "better" moves?

That and typically a sentence questioning/explaining your move every few moves. The variations that it shows tend to be around 3-4 moves deep, and leave with one player having a pretty good position over the other. It's a lot of missed tactics (some strategy, but mostly tactics). It also makes use of chess annotation symbols, which if you can read explain things quite well.

Here's an example:
C50: Hungarian Defence and Giuoco Pianissimo

Hey, Eric? Mind sending me the notation for your game against Luci?
Sent. Btw, I'm using Fritz to run a deep analysis on our game. I'll send you that when it's finished if you'd like.


Awesome. Thanks!

The annotation from our game is the one above. It has some interesting ideas for each player, I'd say it's worth a gander.

Luci, I ran analysis of our game earlier today. Would you like a copy?

I would if I could figure it out. I get the moves, but I'm not sure what the analysis is trying to say. For example:

1.e2-e4 e7-e5 2.Ng1-f3 Ng8-f6 3.Nb1-c3 Nb8-c6 4.Bf1-c4 Bf8-c5 5.d2-d3 d7-d6 6.Bc1-g5 Bc8-g4 7.Nc3-d5 last book move 7...Bg4xf3

What is the "last book move 7...Bg4xf3" mean? I'm a very casual player, so I'm not super familiar with ALL the rules and terminology. Like "book move" or whatever. What's that?

Book move is really the only program specific term. Fritz has a database of all openings, last book move means that was the last move part of a recorded opening, so the next move is all fresh territory as far as it's concerned.

If you do a google search for chess annotation symbols (not notation, which google will suggest) you'll see what things like -+ and +- and ?! mean.
