Chess is a very frustrating game. That's for sure!
I think it is most frustrating in the first couples of years that you play because most people haven't learned to look at the board yet. You get caught off guard a lot and it isn't fun. Combine that with locking in your own pieces so that you don't have much you can do and you have a bad situation.
At least that was the case for me.
Of course the other frustrating thing was that I expected to win! It took a while for me to get over that one too!
All the time in the world isn't going to help you to see something you can't see.
