reza: it would be too easy though to perserve (or even raise it) your bkr in tournament games ... like when i am playing a chess tournament .. at which i can only win against a few other players .. and will lose the most .. i can know already when the tournament starts which games i will lose ... i will them let them time out (or resign?) within 2 moves .. thereby my bkr wont drop by those games ... i will only play the games which i think i can win .. thereby giving my bkr a chance to go up .. and 'never' go down

i only suggest this for tournament games .. as you are put against an opponent .. instead of chosing it yourself

i can imagine people making use of this

as games timed out (and resigned) after the 2nd move are calculated into the bkr .. why not the ones before the 2nd move ?

games which are deleted before the second move are something else .. that is the solution to games which are started by accident
(and you cant delete tournament games (i think))
