WhisperzQ: perhaps you might find it easier for correspondence games if you write down the variations you considered. I have been known to write down moves on a scrap piece of paper and scribble over the entire sheet in frustration when a single missed variation leads to a mess! As far as thinking ahead (which is actually more critical in OTB tournaments) I think it really depends on the position as to whether three moves is superior to seven. as a side note, how did you get to 2100 without thinking further than three moves, you must mean you can only think (more) accurately in a three move analysis tree?
