Hi Ali!
1. I used to recommend, to switch Tutor-Mode off. However, I presently start to think, that this is a good option for a beginner. But you are not a beginner any more. For an experienced player I would prefer to play without Tutor and concentrate on your own play. Find the errors later with the analysis.
2. For the analysis "Expert" setting is okay for checker play in most cases. Only for very complex situations I'd recommend to use "World Class" or even "Supremo".
However, "Expert" is bad for cube handling. GNUBG blunders with the cube regularly at "Expert" setting. So even if the computer is slow, I'd recommend not to use "Expert" for cube analysis.
3. The move filter is of only little interest, IMHO. I normally use the "normal" move filter. For complex positions (i.e. backgames) a bigger move filter may be better. But for such positions I'd recommend to conduct a rollout anyhow.
4. I experience for myself, that I often play to fast when playing a bot. Often I tend to take risky double, I'd never take live. So I try to concentrate and play the bot as if it was in a life tourney.
