KEG: Post II
11... a6
11...Nd4 and 11...Ne7 were also good options for Black here. 12. Qf2

This does prevent 12...Nd4 and anticipates Qb6, White could also have played 12. Bd2 to be able to castle long. 12. Rh1--getting the Rook off the a7..g1 diagonal and freeing the Queen from defending the h4 pawn was also a possibility. 12... Qb6
Black avoids a number of tactical problems by getting the Queens off the board, but White gets a noticeably better endgame. On balance, 12...b5 looks better. 13. QxQ
Maroczy at Munich 1900 always seemed happy to get to the endgame. In addition, trading Queens here looks best. 13... NxQ
That White has the better chances in this endgame is clear from the following diagram:  click for larger viewWhite has the two Bishops and Black's Bishop is a miserable specimen at this point. But how can White make progress? 14. Be3
"!"--Tournament Book.
14. Bd3 was also good, but Maroczy's move posed awkward questions for Black. Showalter responded with the reasonable: 14... Nd7
The question, is whether Showalter, rather than further clogging up his position, should have played 14...d4. As the Tournament Book's analysis shows, White gets a good game after 14...d4 as follows: 15. Bf2 dxN 16. BxN cxb2 (inferior is--again citing the Tournament Book's notes-- 16...Ne7 17. bxc3 ["!"--Tournament Book] Nd5 18. Bd4 ["!"--Tournament Book] Nxf4 19. c4 ["!"--Tournament Book and White is much better) 17. Rb1 with a small edge for White. Both 14...Nd7 and 14...d4 have their points. Showalter's move is perhaps sounder, but I always prefer active play and would opt for 14...d4. 15. Bf2
White has several reasonable plans available. 15. Ne2 and 15. 0-0-0 are the beginning of two such other plans. 15... Ne7
15...f6 is--as Gligoric has noted--one of the themes of Black's play against the Steinitz Advance variation and was probably best here. 16. Nd1
This move, characteristic though it was of Maroczy's remarkable powers of defense and anticipation, seems to go one step too far in its caution. 16. Bd3 and 16. b4 both seem better. 16. 0-0-0 was also to be considered. After Maroczy's 16. Nd1, the position was:  click for larger viewMaroczy may still have some advantage here, but the line-up of his pieces does not look very impressive with only his Bishop having advanced beyond the first rank! 16... Nf5
While Showalter's move was not terrible, the thematic 16...f6 still looks best. 17. c4
I guess Maroczy played 16. Nd1 so he could play 17. c4. But I am still not all that impressed by White's position. 17. Ne3 or 17. Be2 look better than the text. 17... dxc4
The Tournament Book devoted considerable analysis into the possibility of 17...d4 here. Like the text, it seems to result in approximately equal chances. A) If then 18. Bd3, Black is fine after 18...Nc5, although the follow-up line given of 19. BxN (14. Bc2 was better and sufficient for equality, the text seems to allow Black to get the better game) 19...exB (19...gxB would be better). B) The crucial line after 17...d4 begins with 18. b5, and if 18...a5 19. b5 and White is somewhat better. This appears to be best play after 17...d4. 18. Bxc4 b5
19. Bd3 Bb7
20. Rc1 Rc8
Black should perhaps first play 20...f6
21. RxR BxR
22. Ne3
This left:
 click for larger viewWhite still has a small edge but Black should probably be able to hold the game. From here, however, and as I will discuss in my next post on this game, Showalter erred and then blundered and was dead lost after his 23rd move. |
