Its a great game but has a major problem that needs to be fixed.
A player shouldn't be allowed to resign. There is nothing more frustrating than lining up an attack that guarantees to win the opponents Queen and they resign before you can take it! Given they are stuck in the game anyway until it is finished, make them play out the position.
Allowing resignations makes the game way too unbalanced and unpredictable.
