Here's the thing: it's possible to get away with playing the Latvian at lower levels, and your results may even improve because your opponents will be unfamiliar with it. However, as you improve, your leeway for playing sketchy openings will lessen, and you'll end up having to scrap it and learn a new opening entirely. Might as well skip the in-between and play a main line opening right away.
I discovered it today and it ooks a pretty good one, but as moves are super amazing and awesome, playing in a 2|1 format isn't so good. Have y'all played it?
