Here is the game score. I believe also that black will win this, even if better defensive moves are found. Tartakower in the game has many threats 1. positioning the Knight on h5 via f6 2. playing e5 to activate the bishop 3. Bringing the Rook into play 4. Having the g and h pawns advance if necessary In the meantime, white's pieces are difficult to coordinate. They are cramped and are getting in the way of each other. All speculative stuff, as detailed analysis would be lengthy. Computers will assist in finding better defensive moves, but they may also come up with better attacking moves for Black.
