CCC Forum v Daydreamer 1.61 + Dedicated (Chess 960)

[Spacious_Mind]

24 Hours of hard searching and MDC plays:

32. ... hxg5

[d]1r3rn1/pq4pk/3pNp2/2p2PpN/2PpP1QP/2bP4/8/3R1RK1 w - - 0 2

I really liked and hoped MDC would play 32. ... Kh8. But it threw out this move after about 10 minutes.

Best regards

Nick

hxg5

black has same problems as one move before, with the h column open

Miguel
PS: black is forced to play fxg5. It may be able to resist a bit placing a Knight on f6. We should consider f6 avoiding that followed by, at some point, Kg2-->Rh1 (Qh3?)
Or Qh3 Nh6 f6?

Miguel

Yes, I thought Kh8 was interesting because it could still have created the Fortress if White were to allow the exchange of the two Knights for Black's Queen and Pawn.

if 33. hxg5 fxg5 (forced) 34. Qh3 Nh6 (forced) 35. f6 is very strong (undermining h6). g4 36. Qh4 g6 37. Ng5+ Kg8 38. Ng3 and black's positions falls apart.

The transposition is very interesting.
33. hxg5 fxg5 34. f6! gxf6 (Nxf6 Nxf6 Rxf6 Rxf6 gxf6 Qh5+ & Qg6+ & Kg1 --> Rh1 +-)
and now 35. Qh3. if Nh6 Nxf6+, so black can only play 35...Kg6. 36 Qf5+ Kh6 (Kf7 Nxf6 +-) 37. Rf2 Ne7 and I think that 38. Rh2! Nxf5 39. exf5 and black cannot avoid mate with Nxf6#.

If would be nice if we could crash the silicon beast with this queen sacrifice!
Am I missing something? It looks straightforward.

[P. Villanueva]

33. hxg5
Then, after 33. ... fxg5 white has two very strong options:
34. Qxg5

34. Rf2 (or Rf3) (I don't know if there is any difference between those) followed by Rh2 (Rh3)

hxg5

[Graham Banks]

33.hg is the forum's move.

[Spacious_Mind]

Thanks, taking 33. hxg5 as the Forum move.

I thought f6 was the best, but there are some little nuances in the lines I thought yesterday. In some of them, at one point after a hypothetical Kg2 (with the idea of Rh1) there are some annoying Rb2+. For that reason, the move I vote is Rb1. That forces Bb4 and now we can do whatever we wanted, but those tactical details are gone. Besides, The rook that was inactive (Rd1) now can participate with an eventual Rb2 --> Rh2 leaving the Rf1 in the f column playing its role.

34. Rb1 Bb4 35. f6 Nxf6 36. Nxf6+ Rxf6 37. Rxf6 gxf6 38. Qh5+, Qg6+ Rb2 --> Rh2 winning.

34. Rb1 Bb4 35. f6 gxf6 36. Qh3 Kg6 37. Qf5+ Kh6 38. Rb2 Ne7 39. Rh2 Nxf5 40 exf5 and mate in the next couple of moves

if after Rb1 black do not cover with Bb4, it loses very quickly and easily.

34. Rb1 Qxb1 35. Nxf8+ winning
34. Rb1 Qa6 (or c6) 35. Rxb8 Rxb8 and f7 is not defended, so Nxg5+ --> Nf7+ and mate in g7
34. Rb1 Qc8 35. Rxb8 Qxb8 36. Qxg5 and black cannot defend g7 w/o losing the whole rook in f8 (Qb7 Nxf8+)
34 Rb1 Qd7 35. f6!! Nxf6 36. Nxf6+ and Nxg5+ winning the Queen in d7
34 Rb1 Qe7 35. Nxg5+ and after Nf4 --> Ng6 the whole position falls apart.

Rb1

Rb1

Miguel

My vote for Rb1 (althought IMO the check after Kg2 only delays the unaviodable)

There is a lot of winning moves: Qxg6, Qh3, Nxg5+, Rf2, Rf3, f6, Rb1.
Rb1 and then f6 seems to be the most straight and simple.
