this kind of game is played between two players, one is much stronger than the other.
it is a game for a beginner to learn how to play defensively with material advantages, and at the same time to learn the offence skill.
i always believe that offence is the best defence, so when you play with a opponent at equal level, you should play attacking chinese chess.

i would like to point out that, to win a 2-knts handicap game against a master is not easy for a beginner, it may take a long time to do it, or you never could do it, if you can't improve yourself.
i would say there are many players at this site they are just a layman.
