If it is common for you to be able to play back a game in its entirety right after the game is finished without referring to notes, is it because you make a point of memorizing the game as it goes along? Or is it more of a subconscious thing such that even if you didn’t particularly want to remember every move, you still would?
For me, the answer would be “No, I cannot reconstruct the moves,” for any game that goes more than about eight moves. On the other hand, if ahead of the game I were offered a million dollars if I could play it back by memory, I am pretty sure I could make use of that incentive and succeed if the game did not go on for more than about 50 moves. But it would feel like an encumbrance on me, and I wouldn’t do it without the artificial incentive of a reward.
