However, all the analysis I have seen shows a bigger advantage for the queen move. It is not clear that Rxe6 is the best move. Therefore, the position is wrong. Either that or we must: 1. Prove that Rxe6 leads to a won game and Qh3 does not. 2. Allow a new solution and discard old results that discount that solution. The only counter argument I have seen against Qh3 is hand-waiving. Nobody has shown any reason at all why Rxe6 ought to be better. Computer analysis all shows it to be worse.
