computer analisys

ok, look at two games:
1) http://ru.lichess.org/analyse/lgeclmb6
2) http://ru.lichess.org/analyse/2joy3si7

1. d4 e6
2. c4 c5
3. Nf3 ...

two same situations.
in first computer analisys show inaccuracy,
but in second game not!
why? >.<

Two main reasons: 1) the computer program used here seems to have been modified pretty significantly (based on results in another thread in this forum), and 2) the amount of time the computer gets seems not to be fixed. If the server is very busy, then it won't get to look as deeply, which means the evaluations will be different. Based on the quality of analysis I've seen from the engine here, I honestly wouldn't worry about anything it shows that isn't an outright tactic.
