This game was strange; I made a mistake as white and black made, according to the computer analysis, no questionable moves.  If one side makes a mistake and the other side plays perfectly the perfect side should win right?

I think the better question is, what value would you put on the computer analysis?

It dones't seem like much of a mistake to me because the next move you played Nxg4 which is what the computer suggested, but now i see you could've won a piece

a lot less now, but it is still helpful with tactical stuff.  i like getting the cpu analysis; it's like getting a tactical grade back on your chess game.

The weirdest part is move 23 when you go up from 1.6 to 2.4 without there being a mistake from the opponent
