KEG: Mason exploited an error by Mieses on move 10 and by move 20 was a pawn up in the ending. Mason carefully nursed this edge to victory without giving Mieses an chances to recover. A rarity at Monte Carlo 1902 from what I've seen thus far: a player taking advantage of an opening mistake and carrying it on to a win without any flubs by the victor along the way. Mason had gotten off to a bad start at Monte Carlo 1902, and was in next-to-last place after six rounds and still down in 16th place as he began this 9th round game. By contract, Mieses had won his first three games and, despite a loss to Tarrasch, was still in fifth place as he sat down to play Mason. By the end of the tournament, these two players were nearly tied, Mieses finishing in 12th place with Mason in 13th 0.25 points behind (under the strange scoring system used in this event). 1. c4
Mieses was an attacking player, so this choice of opening was a good selection by Mason who even at this stage of his career (when sober) was a fine positional and endgame competitor. 1... e5
Predictably, Mieses chose the most aggressive response. 2. Nc3 Nf6
3. g3

The move 3. g3 has been played countless times since this game,including by the likes of Carlsen and Caruana. Mieses obviously was unprepared for 3. g3, and badly misplayed the opening. 3... d5
4. cxd5 Nxd5
5. Bg2 Be6
5...Nb6 or 5...Nf6 are better. But even after the text Mieses' position was not all that bad...yet. 6. Nf3 Nc6
7. 0-0 Be7
8. d4 exd4
8...NxN looks better, but Mieses' move seems playable. 9. Nxd4

9...NxN(c3) was best.
10. QxN
Stronger was 10. BxN which gives White a considerable positional advantage; e.g., 10...c6 11. QxN 0-0 (exploiting the pin) 12. Rd1 Bf6 13. Qe4 BxB 14. NxB cxN 15. Rxd5 Qb6 16. Rd7. After the text (10. QxN), the position was:

The losing move. It is to Mason's credit that he never permitted Mieses to recover after this blunder (which ultimately cost him a pawn) 11. Qa4+!
Did Mieses overlook this resource? Black was now busted. 11... c6
Perhaps Mieses had thought he could respond 11...Bd7, but now realized that he would then be crushed with 12. Qe4+ Ne7 13. Qxb7 Rb8 14. Qxa7 12. NxN BxN
 click for larger viewAlthough perhaps not apparent at first sight, this position is a straightforward win for White, as Mason proceeded to demonstrate. 13. Rd1! b5
Best, though insufficient to avoid loss of a pawn. 14. Qc2 Qc8
15. e4! Bc4
Once again, best; and...once again...inadequate to avoid material loss. 16. e5
16. Bf4 was also good.
