I'm a novice player trying to learn to beat microstakes, with substantial leaks in my play. While it's easy enough to find opening ranges and discussion online, it's much harder to find concrete advice on calling ranges facing each position, defending 3-bets, and etc.

Is Pokersnowie's preflop advice considered solid enough for microstakes play? Does it tend to err on one side or the other? It seems to line up reasonably well from the gameplay videos I see posted on RIO, but I'm curious if this is a decent place to start.

Obviously, I know that you want to be adjusting your play, not following a chart. However, I'm playing Ignition, so I won't generally have extensive HUD stats on any of my opponents, so it's particularly important that I have a reasonable baseline (then if I'm in a cash game with them for a half hour, I'll be looking for their tendencies to adjust around).
