KEG: Post #2
After the trade of Queens on move 28, the game was about even. But from here on Rosen's play was extremely weak.
32. Bc2
Courting trouble. Rosen should simply have traded Bishops with 32. BxB
33. Nc1
A useless move. 33. h4 was better.
34. b3
As Rosenthal correctly notes in the Tournament Book, 34. Bxg6 loses to 34...Rg7!. But Rosen should have played 34. b4 here.
35. Bd3
Creating a target that allows Maroczy to create a pawn steamroller in the center. 35. a4 was best.
36...Rf5
An awful move that allows Rosen to solve most of his troubles with 37. RxR (luckily for Maroczy, Rosen missed this chance). Maroczy should have played 36...Kh6 here.
38. a3
Ignoring Maroczy's threats. 38. Rd1 was best.
38...Kf6
38...h5 was much better.
40...Ba4
A good move that, among other things, prevents Rosen from playing Rd1.
41...Rc8
Maroczy here fails to follow up properly. 41...h5 (or even 41...Rb8) were better.
42. Bg4?
A very poor move that allows Maroczy to wreck the White King-side pawn structure. Did Rosen overlook that he could not recapture with his Rook?
44...Bc2
44...Bb5 was much stronger.
45. Kh2
Why not the seemingly obvious 45. Rf1+
45...Re7
I do not understand this move at all. 45...Rg5 seems best.
48. Ne2
Avoiding 48. Kg3? d4!
50. Ne6+
The losing move. Rosenthal suggests 50. Nxd5, but after 50...RxR 51. NxR Bb3 White seems lost. Best for White here was 50. RxR with reasonable prospects of holding the game.
52. RxR
Rosenthal wrongly claims that 52. Rh3+ was better, but after 52...RxR+ 53. KxR Rc3+ White's mating threats are at an end and Black wins even more easily than after the text. On any move, however, White is lost here.
55. Rxd5
55. Kh3 was better, but it is too late for White to save the game now.
55...Bb3
This wins, but Maroczy had an even more decisive line beginning with 55...Kg4.
56. Rc5
Trading Rooks is hopeless, but his chances of surviving after 56. Re5 little or none.
I will cover Maroczy's cute winning procedure from here in a later post.
