It's more about knowing a players level of reading a map. The terrain is the canvas on which we paint our master pieces. Players I don't know, I am not sure how well they can read a map, how well they might predict how the game will play out. Playing someone who knows little about the game is actually harder IMO. Those types of players are just not able to identify the key parts of the map and how to cover the terrain. This makes them more unpredictable. Against good players, they can read a map, know where the high-speed avenues to the VC area are, know where they should place the Gun to cover those key choke points, how to funnel an attack into that kill zone, how to cover the Gun with Infantry, etc. I doubt I am the only one who can and does do it. I can still be surprised from time to time, but it doesn't happen often.
IMO, ATTACKERS should stop worrying about where HIP's and Concealed units are and just get on with it. Make your opponent put it on the board. Don't give him a super juicy shot, but if he is going to hold fire waiting on a juicy shot, he should find himself facing a hellacious task getting out of his position as I surround him with HS's and Squads making his departure a challenge. One the HIP's and the Concealed stuff is on the board, you can sort out the rest as you move along. Respect the unknown, just don't let it paralyze you. -- jim
