premoving

I have to state very clearly that i have player lots of (ca
30) lightining games on FICS and EVERY time i used
premove while playing endings having couple of second
Jin finally got terribly stuck and i lost ALL of these
games on time. cant tell you exactly how does that
come to this, but as a result i see one of my figures in
dark and when id like to make a move it says illegal
move (and the position on the board seems to be
corrupted, as it is impossilbe to enter from keybord a
move that actually WOULD be legal judging on a
position shown solely). frankly speaking you software
does not come to be useful for lightning games so far.
