Any games that are deemed to be biased
Should be played as a pair of games to remove the bias
To keep step in both games only allow move in game with fewest moves made

Which games do you mean are most biased games? Here at LG and in general.

1st player win

Gomoku (not pro)

Four in a row

Hex

2nd player win

Reversi 6x6

Hex has the pie rule... so actually it is a win for player 2

Maybe add a split rule (like blackjack if both cards are of the same value)

The game becomes two, with and without the pie rule been used

Still hoping for Hex with the 12* placement rule to see how it compares to Catchup.
