Ulhumbrus: An alternative to 10 d4 is 10 a4, because then 10...b4 concedes the c4 square to White, as in the game Keres vs A Tarnowski, 1952An alternative to 31 Nxe5 is 31 Nd4 when the N threatens the b5 pawn as well as Nf5
An alternative to 34 Rxc4 is 34 g3 after which Black's entire Queen side and Black's entire King side have become potential targets for attack
An alternative to 37 Qf3 is 37 Qf5 keeping an attack on the s5 pawn eg after 37...Ng4 38 Bg3
An alternative to 41 Rd7 is 41 Bc5 with perhaps the superior minor piece
An alternative to 44 Rc3 is 44 Rc5 attacking the e5 pawn and threatening to attack the a4 pawn by Ra5.
After 45...Rxd6 Nakamura's Rook attacks all of the four squares in the d file in White's half of the board, d4, d3, d2 and d1 and White's Rook and King cannot keep Black's Rook out of all of them. All the same, White may able to draw. However Polgar wants more than a draw although by now her advantage, if any, may be no longer sufficient to win
Polgar's play suggests poor playing form. Polgar holds the advantage for much of the game, lets it slip gradually by several errors, and then finally goes too far trying to avoid a draw and loses.
