2 suggestions so far:
A) Prevent White from playing 2 Squares in a row on the first two turns.
B) Black has 1 less Square and 1 more Circle (or 1 more Triangle)
Any other ideas besides C) Combining A) + B) ?
A) can be tried in the current config of the game. It does counterbalance a little bit, but enough so?
Let us know what you think.
