I'm interesting in picking up Mu but there are a couple of things that I am still not too sure of. Is there a set way for stein placement? I'm watching videos but I just can't figure out stein placements outside of doing combos. Is the goal to place steins in front of or on top of the other player for habakiri/totsuka? Also, is the oki thread at the bottom of the board still relevant in bbcp?
