During recent online chat with gamers, I asserted that 'go' (and possibly othello) had a larger decision space than chess.
After reading Wikipedia, I realized I failed to account for othello and go 'saturating' the board with pieces and dramatically limiting available moves in the late game.
The opposite is true for chess. The decision space dramatically increases as the board is cleared.
From my non-expert opinion, this phenomenon would shift the balance away from position and towards the individual skill of the expert players. This skill is at the heart of the competition itself. The "precision" of skill would be more relevant in the late game.
So my question is: do master players naively assume the path that brought them to the weaker position is representative of the late game? Does the balance shift away from position enough to warrant the stronger position proving his mettle in late game?
