In your (brainking.info) blog, you mentioned being able to request more chips...I have a few suggestions for this feature:

1. Only let people renew chips only when they go bust.

2. Let every player have 5 (or some finite number) of free renews. So players learning can get more chips at the beginning. All 5 can be used in one hour, one day, however long they need. Again, can only renew if you don't have chips. So, you can't use them all up to get 5 times the normal starting amount.

3. Let players always get one renewal per day. Again, only if you don't have any chips.

4. Reward people for playing other games on brainking. You could have a daily bonus players could grab, based on their activity with the other turn based games. You could base it on number of ratings (provisionsal?), number of running games, number of moves, or any combination.
