KEG: Post II
After Rosen's 17...e5 Brody had various means of winning material. 18. Nxe5
This move is sufficient to win, but 18. bxa6 was even more decisive. 18... NxN
19. BxN Bxc5
If Rosen thought this move would enable him to maintain material equality (perhaps he expected 20. dxB? RxB), but he was quickly disillusioned. He should have played 19...Ng6, though that would have left him a pawn down. But matters will be much worse after the text. The position after 19...Bxc5 was:

Even better was 20. bxa6 bxa6 21. Nxd5!, since 21...QxN loses to 22. Be4 and 21...Rxe5 loses to 22. dxR (since 22...QxN is met by 23. Be4). But the text is plenty good, and also wins. 20... QxB
21. Nxd5 Qd8
22. QxB
White is now two pawns up with ample further attacking prospects, the position now being:  click for larger viewRosen's best chance here, as noted by Rosenthal in the Tournament Book,lay in 22...Ne6 23. Qc4 Ng5 (better than Rosenthal's 23...Bd7 which gets crushed by 24. bxa6). But this was still hopeless. So Rosen decided to go for an all-for-nothing attack. 22... Bxh3?!
Had Brody taken the Bishop, Rosen might have had half a chance (23. gxB Rc8) as pointed out by Rosenthal. But Brody was having none of this, and made sure of major material gain with an intermediate move apparently overlooked by Rosen: 23. Nb6!
Black is busted.
23... Nd7
This is hopeless, but the "better" moves 23...Bg4 or 23...Qh4 were likewise unavailing. 24. Qh5 g6
Perhaps 24...Nf6 was a little better, but by this point Rosen is doomed to the loss of substantial material. He should probably have resigned. 25. QxB NxN
26. axN
26. bxa6 would have left Rosen without resource. But the text, which puts Brody a piece ahead with the better attacking chances to boot was simpler. 26... a5
The position was now:
