The opening database is great, but...
Hints always lead to loss
Update: Thank you for the recent update. It no longer crashes from what Ive seen. Unfortunately it is still having an error when using the hint feature. Occasionally it will tell you take make an illegal/impossible move. Ive seen this in late game multiple times playing black. It will tell me to move the king to a space occupied/illegal. At this point it will only allow you to make a move for certain pieces.
Thank you for the program. I look forward to further improvements.
