Kriegspiel
:p |
|
| Feb-09-06 | | psmith: <Kriegspiel> 27... Nh7 28. Qh6 with large advantage to White. |
|
| Feb-10-06 | | Kriegspiel: <psmith> OK, I'll bite: what's the large advantage? 28...Rxc1 29.Rxc1 Bc8. What next for White? Kriegspiel
:p |
|
| Feb-10-06 | | psmith: <Kriegspiel> After 27...Nh7 28. Qh6 Rxc1 29. Rxc1 Bc8 White plays 30. Rc3 with the idea of Nf5 followed by Rg3 or Rh3. Here are sample analyses (which I obtained with the help of Fritz) 30... Bg4 31. Bh3 Bh5 32. Nf5 gxf5 33. Bxf5 Bg6 34. Bxg6 hxg6 35. Qxg6+ Kh8 36. Rh3 30... Kh8 31. Nf5 Bxf5 32. exf5 Rg8 33. Rh3 Rg7 34. fxg6 fxg6 35. Rg3 30... Nf6 31. Bh3 Ng4 32. Bxg4 Bxg4 33. Nf5 gxf5 34. exf5 (idea Rg3) Bxf5 35. Rg3+ Bg6 36. Rh3 30... e5 31. dxe6 Qf6 32. exf7+ Qxf7 33. Rf3
White has a big plus in all these lines and more.

| Feb-10-06 | | Kriegspiel: <psmith> I have no time tonight but will take a look tomorrow morning. I do notice, however, that none of your lines includes 30...Bd7. What does Fritz say about that? Kriegspiel
:p |
|
| Feb-11-06 | | psmith: <Kriegspiel> If 30...Bd7 31. Nf5 Bxf5 (31...gxf5 32. Rg3+) 32. exf5 with the threat of Rh3 and Black has no defense. That is the threat I mentioned at the beginning of my last message. |

| Feb-11-06 | | Kriegspiel: <psmith> You seem to be playing a different game than the one shown on this page. Here's the hypothetical continuation: 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 Bd7 31.Nf5 gxf5 -- and now how is White going to play 32.Rg3+ considering the fact that there is a pawn at d6 blocking the way? (A pawn protected by another pawn at e7.) Kriegspiel
:p |

After 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 Bd7 31.Nf5 gxf5, the white Rook is at c3, not c6. How does a pawn at d6 block a rook at c3? Perhaps you haven't had your morning coffee yet. Set up the board, move the pieces according to the notation I typed, and then check back in again. |

| Feb-11-06 | | Kriegspiel: <psmith: How does a pawn at d6 block a rook at c3?> Something to do with Bell's Theorem, no doubt. Seriously, I seem to suffer a perpetual case of "chess dyslexia" when regarding algebraic notation from the Black side of the board. Well. I'll have another look, as you suggest. Kriegspiel
:p |
|
| Feb-11-06 | | Kriegspiel: <psmith> OK, looking at one of those lines: 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 e5 31.dxe6 Bxe6 and now if 32.Bh3 then 32...Qf6. Kriegspiel
:p |
|
| Feb-11-06 | | psmith: <Kriegspiel> 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 e5 31.dxe6 Bxe6 and now 32. Nxe6 fxe6 33. Qxg6+ Kh8 34. Qxe6 and White is just up two pawns. There are other ways to win as well. |
|
| Feb-11-06 | | Kriegspiel: <psmith> Here's another possibility in the same line: 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 e5 31.dxe5 Bxe5 32.Nxe5 fxe5 33.Rh3 Qc7 34.Qxg6+ Kh8 and then if 35.Qxe6, 35...Qc1+ 36.Bf1 Qd2 threatening 37...Qxf2+. Kriegspiel
:p |
|
| Feb-11-06 | | Kriegspiel: <psmith: ...and now 32.Nxe6 fxe6 33.Qxg6+ Kh8 34.Qxe6> and Black might follow up with ...Rg8 followed by ...Qg5 giving him some options. Also, ...Nf6 is an idea somewhere in the mix. Kriegspiel
:p |
|
| Feb-11-06 | | psmith: <Kriegspiel> I am not sure what the point of your last comment was since it doesn't follow out the line I gave, in which White plays 33. Qxg6+. 33. Rh3 is not as strong as 33. Qxg6+, because it lets Black onto the c-file. I think it's still winning -- but I don't need to consider this possibility to show that White is winning in the original line. But anyway, Black obviously has lots of alternatives at every step (he doesn't have to play 28... Rxc1, for example) but I'm convinced from analysis both on my own and with Fritz that they all lead to advantage for White. If you have some line in which Black is clearly equal and White's best moves have been played, give it a shot. |
|
| Feb-11-06 | | psmith: <Kriegspiel> Your message crossed with mine. I was replying to your comment about "another possibility in the same line." Now you seem to want to consider 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 e5 31.dxe6 Bxe6 32. Nxe6 fxe6 33. Qxg6+ Kh8 34. Qxe6 Rg8. You think you have some ideas of Qg5 and Nf6. Well, OK, Black isn't mated yet, and he has some resources if White isn't careful, but I think White is two pawns up, and clearly winning. I only said (in the beginning) that after 27...Nh7 28. Qh6 White had a big plus. 2 pawns up is a big plus. Do you deny that? |

| Feb-11-06 | | psmith: <Kriegspiel> 27...Nh7 28.Qh6 Rxc1 29.Rxc1 Bc8 30.Rc3 e5 31.dxe6 Bxe6 32. Nxe6 fxe6 33. Qxg6+ Kh8 34. Qxe6 Rg8 and now 35. Rg3 stops Black's dreams of counterattack. I get the impression you're just throwing moves out without considering how White might reply. That's not analysis. |

| Feb-11-06 | | Kriegspiel: <psmith: I get the impression you're just throwing moves out without considering how White might reply. That's not analysis.> OK, that's a fair assessment. I'll stop now. I'm rather tired anyway. Kriegspiel
