| Dec-09-04 | | crafty: 39...♖gc8 40. ♘e2 ♖xe2 41. ♕xd1 ♖ec2 42. ♕d5 ♖2c5 43. ♕d2  (eval 0.80; depth 15 ply; 500M nodes) |
|
| Dec-09-04 | | maheshml: Ng6 is really excellant.why 96..Qxa7 is mandatory |
|
| Dec-09-04 | | Nickisimo: My idea was 35. Qf7 Rg8 36. Ng6+, but the rook on c5 and Black's pawns stop the queen from giving any immediate check on the h-file. |
|
| Dec-09-04 | | beenthere240: <marco65> your line ending in 42.Kf1 is like a problem: 43 Rf4 is looming and anyway black tries to block it gives up a piece or creates another mate. |
|
| Dec-09-04 | | admiralnemo: yep, i was missing 38..Rg4, oops |
|
| Dec-09-04 | | Cyphelium: <admiralnemo> If 35. Ng6+ hxg6 36. Qf7 Nxd1??, then 37. Qxg7 mate wins at once. Black can play 36.- Rg8 instead, when it's hard to see how white should continue. |
|
| Dec-09-04 | | admiralnemo: cyphelium, yep also i forgot that after qf7 the g6 pawn that took the knight is blocking qh5+ |
|
| Dec-09-04 | | admiralnemo: i ended up deleting my line and now everyone willl be thoroughly confused by our discussion :) |
|
| Dec-09-04 | | admiralnemo: then there is the further complication that the rook would just take the queen if it eventually made it to h5 anyway. Why must our opponents have pieces! |
|
| Dec-09-04 | | patzer2: <ice lemon tea><marco 65> After 35.♖xg7 ♔xg7 36.♖d7+ ♔h6 37.♕f7 ♘e2+ 38.♘xe2 ♖g8 39. ♕xh7+ ♔g5, White has at least nine different 40th move options leading to mate (including 40. h4+, which you both selected). Another alternative line, which I also like here, is the seven-move mate with 40. ♕h4+. Play could continue 40. ♕h4+ ♔g6 [40...Kf5 41. Nd4+ Kg6 (41...Ke5 42. Qf4#) 42. Qh7+ Kg5 43. f4+ Kg4 44. Qh4#]41. ♘f4+ ♔f5 42. ♕h7+ ♔g4 43. ♕h3+ ♔f3 44. g4+ ♔e4 45. ♖e7+ ♖e5 46. ♕g2#. |
|
| Dec-09-04 | | Marco65: <patzer2> At first I discarded 40.Qh4+ because I didn't see how to continue after 40...Kg6 41.Nf4+ Kf5 42.Qh7+ Ke5, maybe White will be contented by 43.Qe7+ Kf5 44.Qe6+ Kg5 45.h4+ Kh6 46.Qxf6+ Rg6 47.Rxh7+ Kxh7 48.Qxg6+ Kh8  or did you see anything better? |
|
| Dec-09-04 | | williscreek: I thought 35. Ne6 looked good, but Rg7 sure looks stronger. |
|
| Dec-09-04 | | maxundmoritz: I would like to learn more about the line that <who> suggested originally: "35.Rxg7 Nd5 36.Rd7 Nxf4 37.exf4 Qe4 38.Qxb6 is black's best". I also think that 35..Nd5 is a better choice than 35..Kxg7. Any thoughts on this? |
|
| Dec-09-04 | | beenthere240: <maxundmoritz> It probably lose more slowly, but as a practical matter, with 35...Kxg7, you can hope that white's calculations are wrong and you'll end up a rook ahead. With 35. Nd5, you're giving up at least a couple of pawns for the dubious pleasure of prolonged torture. |

 | | Honza Cervenka: 35.Rxg7 Kxg7 36.Rd7+ Kh6 37.Rxh7+ is sufficient too and it is really great fun. Continuation 37...Kg5 38.Rh5+ (38.h3 wins too.) 38...Kg4 39.h3+ Kf3 40.Rxc5 bxc5 41.Qxc3 leaves no room for doubts. If 41...Qe4, then 42.Qc1! (threatening 42.Qd1#) 42...Qxa4 (42...Rd8 43.Qf1 threatening 44.Qg2#) 43.Qf1! Ke4 44.Qd3+ Kf3 45.e4#. If 41...Qc6, then 42.Qd3! threatening 43.e4#. If the Queen leaves the diagonal, for example playing 41...Qc8, then 42.e4+ Kxe4 43.Qd3+ Ke5 44.Qd5#. 41...Rc8 leads to a mate after 42.e4+ Kxe4 43.Qe3+ Kf5 44.Qe6+ Kg5 45.Qg4+ Kh6 46.Qg6#. 41...Rg8 is not better: 42.e4+ Kxe4 43.f3+ Kf5 44.Qxc5+ Qd5 45.Qxd5#. And finally if 41...c4, then 42.Qxc4 Rc8 [42...Rd8 43.Nd3! (threatening Qg4# or Ne1#) 43...Ke2 44.Qc2+ Kf3 45.Ne1#] 43.Qe2+ Ke4 44.Qd3+ Ke5 45.Qd4+ Kf5 46.g4+ Kg5 47.h4+ Kxg4 (47...Kxh4 48.Qxf6+ Kxg4 49.Qg6+ Kf3 50.Qg2#) 48.Qd7+ Kf3! (48...Kxh4 49.Qh7+ and 50.Qh5#; 48...f5 49.Qg7+ Kxh4 50.Qg3#) 49.Qd1+ Ke4 50.f3+ Ke5 (50...Kxe3 51.Ng2# is a beautiful mate!) 51.Qd4+ Kf5 52.Qd7+ Ke5 53.Nd3# (53.Ng6# or 53.Qe6#) finishing this great hunt of black King. |
|
| Dec-09-04 | | Rank Amateur: I still like Mendel's line:
35.Rxg7 Nxd1 36.Qf7 Qe4
Black's up a rook, has postponed checkmate, and has threats of his own.
(and I don't how you guys refer to each other with those color-coded tags) |
|
Dec-09-04
| | Honza Cervenka: <Rank Amateur> 35.Rxg7 Nxd1 is refuted by 36.Rxh7+ Kxh7 37.Qf7+ Kh8 38.Ng6# or 37...Kh6 38.Qg6#. |

| Dec-09-04 | | patzer2: <Marco65><patzer2><...I discarded 40.Qh4+ because I didn't see how to continue after 40...Kg6 41.Nf4+ Kf5 42.Qh7+ Ke5> Let's try 40...♔g6 41. ♘f4+ ♔f5 <42. ♕h3+!> [42. Qh7+ wins, but this line is also fun] 42...Rg4 [42...Ke4 43. Rd4+ Ke5 44. Qd6#; 42...Ke5 Qd6#; 42...Kg5 43. Qh5#] 43. Qh7+ Rg6 [43...Ke5 44. Re7+ Kd6 45. Re6#; 43...Kg5 44. Qh5#] 44. ♕xg6+ ♔e5 45. ♖e7+ ♔d6 46. ♕xf6# |
|
| Dec-09-04 | | patzer2: <Marco65> I think I overly complicated the answer to your question. After <40...Kg6 41.Nf4+ Kf5 42.Qh7+ Ke5>, White mates in two with the pretty 43. Re7+! Kd6 44. Re6# |
|
| Dec-09-04 | | apple head: <Although White wins later after a blunder by Korchnoi (39...Nxf2? instead of 39...Rgc8!) there was a neat win with 35.Rxg7!! which gives White a decisive attack. E.g., 35...Kxg7 36.Rd7+ Kh6 37.Qf7 Ne2+ 38.Nxe2 winning.> No its Rg7 Kg7 Re7+ Kh6 Rxh7+!! (Kh7 Qf5 Q/N g6# is next. ) Kg5 Rh5# |
|

| | Honza Cervenka: <apple head> 35.Rxg7 Kxg7 36.Rd7+ Kh6 37.Rxh7+ Kg5 38.Rh5+ is not checkmate as black can play 38...Kg4. For a possible continuation see my comment above. |
|
| Dec-10-04 | | patzer2: <Honza Cervenka>'s enjoyed your line 35.Rxg7 Kxg7 36.Rd7+ Kh6 37.Rxh7+ . In addition to being fun, this line is a great advanced lesson in the "pursuit" or king hunt tactic, containing a number of practical and useful mating patterns. I was surprised when my computer program initially gave this line only as equal, finding the winning pattern only after running for an extended time. |
|
| Dec-10-04 | | Marco65: <patzer2> Great mate in two! These analyses of you and Honza Cervenka are really challenging for me to follow without moving pieces on a board. My habit is to give up a line and try to find another one when I can't find a winning continuation in a reasonable time, that's how I came to 40.h4+. On the contrary you never give up. |
