I don't. I never just throw the game so they can win. I help them with their turn to improve their strategy and skill, and I point out my weaknesses whilst they are still learning though. Today I bought connect 4 and taught it to my son. For the first 20ish games I fully helped him, the next 20ish only if I felt he really needed it. Then after about 50(?) Games he won for the first time because I didn't see his strategy. I feel like he wouldn't have gotten any good at the game had I just let him win. What are peoples views on this?
