I've been trying to get back into chess a bit, and noticed the option to practice certain positions - but I've been puzzled by the rating when playing a "Friendly" game (which gives you feedback for your moves).
During practice, the move that's considered "excellent" is considered an "inaccuracy" in the exact same game against a computer.
I'm not sure about chess notation, I'll try to supply pictures.
The position I reach as black is this one, trying to figure out my next best move:
If I practice this position (here), Bishop to b5 is rated as "good"
But if I do the exact same move in my own game, it's rated as "inaccuracy"
The ratings also seem fairly different (+0.99 vs +0.39). What am I missing here? Is this move good, or inaccurate? Why do I get two fairly different responses for the exact same game position - does it rate differently according to the opponents Elo rating? Or am I missing something obvious?
