i found out that i have played Time per GAME i get a better result than Time per MOVE. i won more games when i accepted invitation with x per game. the reason is my style of playing the game, i always spent less x than my opponent, and respond almost right away after seeing my opponent's move. but my opponent was doing the opposite. they spent lots of x to make a move, not respond right away and logout after seeing my move to get help. they lack the ability to find move over the board. actually i'm playing handicap..i'm always in a waiting position.. i get annoyed and fed up..
