Yes this obviously.
I played the game horribly of course, but Qe2 with the idea of Rd1 is thematic in the opening. I think my mistake was allowing Bg4. I should probably play 10.h3

There are tonnes of lines to check out after Rxd4 exd4 Qg5. I think the main move here is h6, after which I think Nf6+ loses, but Qg3 looks interesting. I think the Nf6+ line loses because:

Nf6+ Kh8, and now,

Qg6 (threatening Qh7#), just fxg6 Nxd7 Rxc4 Nxf8 Rc1+ and black wins the endgame easily.

Qxh6+ gxh6 Nxd7 Rxc4 Nxf8 Rc7.

Qxg7+ has a similar outcome

Qh4 or Qh5 there's just Qe7 (gxf6 leads to draw by repetition with Qxh6+ Kg8 Qg6+)

Nxd7 hxg5 Nxf8 Rxc4 e5 Rc7 e6 fxe6 fxe6 Kg8 and white cannot move the pawn or knight and black wins easily.

These might not be the best lines for black, but they are clearcut.

So, Nf6+ seems to lose. So instead, Qg3 looks like an interesting alternative. It's the same position as playing Qg3 instead of playing Qg5 in the first place, but with h6 pawn there. After Qd8, f6 looks juicy. I'll look into it much later though.

It's just turning out to be a really fun calculation exercise.

I haven't analysed it too closely but 19. f6 looks like it gives you lots of compensation, he can't really stop Ne7+ (19...Rxc4?! 20. Ne7+ Kh8?? and he gets mated) and if he plays R (either) to e8 you have Rxd4 and he can't take it back because of Qg5. So he probably has to play 19...h6 or something and then you have the option of winning back the exchange straight away or figuring out if Qg3 is any good (it might not be great because of Rxc4, Ne2+ ideas)

I wanna make a book: How to Mate Your Opponent but Then Really Pull Out and Lose Instead.
(I'm just going to go over the parts relevant to the book title, otherwise much more analysis could be done on these games. I actually found them to be quite interesting. Maybe some other day.)

Part 1:
http://ficsgames.com/cgi-bin/show.cg...99;action=show

Code:
[Event "FICS rated blitz game"]
[Date "2010.10.27"]
[White "ganstaman"]
[Black "magochess"]
[Result "0-1"]
[BlackElo "1462"]
[ECO "C10"]
[WhiteElo "1406"]
[TimeControl "180+0"]
[Termination "normal"]
[PlyCount "72"]

1. e4 c6 2. d4 d5 3. f3 e6 4. Bf4 dxe4 5. Nc3 Bd6 6. Be3 exf3 7. Nxf3 Nf6 8. Bd3 Nbd7 9. O-O b6 10. Qe2 Bb7 11. Bg5 Qc7 12. a4 h6 13. Bh4 g5 14. Bf2 Ng4 15. h3 Nxf2 16. Qxf2 g4 17. Ne5 O-O-O 18. Nxg4 h5 19. Nf6 Nxf6 20. Qxf6 Rdf8 21. Ne4 Be7 22. Qf2 f5 23. Nc3 Rhg8 24. a5 c5 25. d5 Bh4 26. Qxh4 exd5 27. axb6 axb6 28. Bxf5+ Kb8 29. Nb5 Qc6 30. Na7 Qd6 31. Nb5 Qe5 32. Rae1 Qxe1 33. Rxe1 Rxf5 34. Re7 d4 35. Nd6 Rxg2+ 36. Kh1 Rf1# {White checkmated} 0-1
After 29...Qc6


30. Qf4 Qd6 31. Qxd6# would have been good for me. Unfortunately, I have under 21 seconds to his 1 minute, so I panic and go with a different plan of getting mated instead. I (and it seems my opponent) actually saw my mating threats 1 move later, so black was forced (?) to give up his queen to avoid the mate for a bit, but that didn't help my clock much.

Part 2:
http://ficsgames.com/cgi-bin/show.cg...23;action=show
Code:
[Event "FICS rated blitz game"]
[Date "2010.10.30"]

Kxe3 Ra4 17. g3 Rha8 18. a3 b5 19. Nd2 f6 20. exf6 gxf6 21. Rad1 h5 22. Kf3 Ne7 23. Rhe1 Nf5 24. Nb3 Kd6 25. Nd4 Nxd4+ 26. Rxd4 Rxd4 27. cxd4 Rc8 28. Re2 Rc4 29. Rd2 b4 30. axb4 Rxb4 31. Ke3 Rb3+ 32. Ke2 e5 33. dxe5+ fxe5 34. fxe5+ Kxe5 35. Kf2 b5 36. Ke1 d4 37. Kd1 Rf3 38. Kc2 Kd5 39. b3 Rc3+ 40. Kb2 b4 41. Rf2 Ke4 42. Rg2 d3 43. g4 hxg4 44. Rxg4+ Kf3 45. Rxb4 Rc2+ 46. Kb1 Rxh2 47. Rd4 d2 48.

After 50...Kf2


White must play 51. Rg8 or 51. Rh8 to draw (just pull out a tablebase), but blunders with 51. Rd8. I correctly play 51...Ke1, bringing about a mate-in-23 (seems hard, but soon it will be K+P vs K+R, so not really so hard). But then, in my final seconds, I inexplicably play 52...Kf2, entering the losing side of a mate-in-13 instead of queening my pawn, which was clearly my plan on the previous move.

In the first game, missing 18. Nxf7 is a huge leak and a trivial tactic that you should just be snap-identifying.

It wasn't missed, exactly. I spent nearly 30 seconds on that move. What I was afraid of was either rook moving to f8 pinning my knight. What I did actually miss was that my queen could move away and my rook would still be there protecting my knight.

I've looked at it a lot more this morning now I'm not so tired and I can see why you might reject that under blitz controls. It requires really accurate play to retain the advantage and it gets really sharp if you make any errors.

Yeah, I also saw that in the game one move after I played it. Without checking, I believe I was done to just seconds by that point and was moving with barely any thought. My thoughts caught up to the position a little late...

brag - just won a year's subscription to New In Chess from the ICC trivia contests at the end of GOTD from one of the tourneys

not as good as when I won the thousand Euros of Informant stuff, but probably about a $100 gift just the same

Cliffs on how you won the 1000 Euros of Informant material? I sort of recall you posting about it a while ago, but I can't remember what kind of contest that was

A nice mating net to spot with so little time left on the clock definitely but hey, someone has to represent nit-picky douchebags, right? if I am not missing anything Rb8 would be an easy draw while Rd8 actually gives white great chances to win cause after Rd8 b2 Rd7+ Kh8 Rd7+ Kg7 Rd7+ Kf8 you run out of checks and have to play Rb8 anyway. However, pawn is on b2 now instead of b3, and after black defends it with a rook to the second rank with for example Rd3 Be4 Re2 (always good to make that white bishop face a wall of his pawns), white is in deep trouble because black is threatening Bc5--b6 manouvre to block the B-file so White has to play something like Rb5, but then white pieces are pretty much locked in so if black manages to bring a king in he will win easily. Might still be a draw, but white has chances But of course with so little time left none of this matters and the motive itself counts, so well done!

11-17-2010 , 08:01 AM
I have to apologize - upon further inspection it seems that with proper play by white black is unable to bring his king in to play so it is still a draw. Which means, that you gave yourself a chance to win a game by this neat mating net while still maintaining the draw against best play with white, so definitely +EV Props!

I'm trying to analyze it using the "calculation training" part of Rybka 3.

I've gotten about 7 moves deep and my brain is starting to find it hard to visualize the position lol

It's fun though

Much simpler than playing Rd8 immediately is (I think) Bf7 then Rd8 then Bg6 then checking on d7 and d8 for a draw.

Although there may be a bishop-king setup like with the king on g8, after Rd8+ maybe there is Bf8
*** Chess BBV *** Quote
11-17-2010 , 02:21 PM
Here's my analysis so far without a computer (for Rd8 only)



This took like an hour to analyze (so far) lol

Argh I really want to put it into the engine
