| Nov-21-13 | | Nf3em: In a tactical position like this, the moves to look for are forcing moves: I also looked at possiblity of the Knight fork at g5 but Black has enough antidote for that and so the next possibility is exchange sacrifice at d7 which is IMO the only way to win -- 29.Qxd7 Bxd7 30.Rxd7 Rg8 all forced and after 31.c6 White is clearly winning. |

| Nov-21-13 | | LoveThatJoker: <29. Qxd7 Bxd7 30. Rxd7>  LTJ |
|
| Nov-21-13 | | diagonalley: ... wow!... a rook, bishop, massive passed pawn AND pinned enemy bishop - all for a measly queen... no hesitation here... easy for a thursday |
|
| Nov-21-13 | | M.Hassan: "Medium"
White to play 29.?
White is 2 pawns up
29.Qxd7 Bxd7
30.Rxd7
Now, Bishop on g2 is pinned and White has a passed pawn.
30.........Rg8
31.c6 Qa4!
32.Bxg7 Re8 to provide room for the King to run away from discovered check 33.Bd4+ Kg8
34.Ne5 Qxa2
White lost a Queen+pawn and captured R+2B. White is stronger in materials and has his pieces well positioned towards Black's King camp. Game may continue as below: 35.c7 Rc8
36.Rd8+ Kh7
37.Rxc8
Plus the possibility of promotion of c pawn. Conclusion: 1-0 time to check |

| Nov-21-13 | | TheaN: Thursday 21 November 2013
<29.?>
They let us off the hook this Thursday with a relatively easy midweek problem. The initial moves are fairly easy, but typically any defense coming afterwards is even more quickly neutralized. Given the position that follows, White has no reason to hesitate capturing on d7. <29.Qxd7! Bxd7 30.Rxd7>. Now, theoretically, Black can aim immediately for variations giving up Bg7 too. However, because of the windmill of Be5-Rg7, Black can only play 30....Kg6. h5 meets 31.Nxg5+ which is immediately lost, keeping the windmill intact allows White to at least win back the Queen for R+B, hence being the Knight up and a couple of pawns. The only real challenge is <30....Rg8> though <31.c6> pretty much decides on the spot. Black's majority of the pieces is paralyzed, and the Queen herself is hopeless against a defending march of the c-pawn. The only move I considered for Black is <31....Qa4> for an x-ray attack on the d7-rook. Now, <32.Bxg7> is probably the best move: it keeps the windmill intact and 32....Rxg7 33.Rxg7+ Kxg7 34.c7 loses right away. <32....Re8> or similar, to activate the rook, but <33.Be5+ Kg6/g8 34.Rg7+ with 35.c7 > and I'm pretty sure Black loses quickly. |
|
| Nov-21-13 | | TheaN: I didn't consider g4, but this feels too slow anyway. <Hassan> correctly summarized the problems for Black after the variation I posted above. I quickly played it out myself, but after <29.QxR BxQ 30.RxB Rg8 31.c6 Qa4 32.Bxg7 Re8 33.Be5+ Kg6/Kg8 34.Rg7+ Kh5/Kf8 35.c7 Rc8 36.Rh7 > is nasty enough, in both variations. |
|
| Nov-21-13 | | King Sacrificer: <32. Re4> traps the queen but the win would be harder i guess. That move looks important as it busts <31...Kg6>. Black has to push the g-pawn at move-31 to keep the material balance after a possible queen trap. |
|
| Nov-21-13 | | hedgeh0g: Rather unusually, I guessed the game continuation down to the letter after White's 29th. Not sure if Black's play was objectively best after Qxd7, but it probably represented the best practical attempt in a completely hopeless position. |
|
| Nov-21-13 | | ozmikey: Very straightforward for a Thursday. |
|
| Nov-21-13 | | morfishine: <29.Qxd7> 29...Bxd7 30.Rxd7 Rg8 31.c6 looks fairly overwhelming ***** |
|
| Nov-21-13 | | gofer: An exchange of our Q+B+R for R+R+B+B, doesn't seem that okay on the face of it, we seem to
have gone an exchange down, but the kicker is Pc5 as we lose the final exchange black retakes
with the king and we get to play c6. We are now in a R+N v Q end game. The move order may
be slightly different as c6 may come earlier than all the other exchanges, but Qe4 has to
stop Pc6 and that is a pretty tall order!
<29 Qxd7 Bxd7>
<30 Rxd7 Rg8>
<31 c6 ...>
~~~
Yep, pity every one is saying it was "so easy". So not much credit today... |
|
| Nov-21-13 | | Nick46: I got Ladislav's first two moves but didn't know how Smejkal would react from there. No dishonour. |
|

 | | patzer2: 29. Qxd7! Bxd7 30. Rxd7 Rg8 sacrifices the Queen to pin the Bishop on g7 and force the Rook to g8. This allows 31. c6! with a winning passed pawn combination. |
|
| Nov-21-13 | | zb2cr: Managed to get this, but it was a struggle. |
|
Nov-21-13
 | | Penguincw: I was trying to fork the king and queen. It didn't work. |
|
| Nov-21-13 | | Tiggler: The trick here is that there is no trick here: just crash through. Only saw it after realizing that none of the tricky stuff would work. |

 | | agb2002: White has a bishop, a knight and two pawns for the bishop pair. Black threatens 29... Rxd6.
The simplest way to win I can find is 29.Qxd7 Bxd7 30.Rxd7 Rg8 31.c6: A) 31... g4 32.c7 gxf3 33.c8=Q Rxc8 34.Rxg7+ Kh8 35.Rxc8#. B) 31... Kg6 32.c7 Bxe5 33.Nxe5+ Qxe5 34.Rd8 Qxc7 35.Rxg8+ wins. -----
The obvious 29.Qe6 looks problematic after 29... Rxd1+ 30.Rxd1 Re8 31.Qf7 (31.Qd6 Bxe5; 31.Rd4 Qb1+) 31... Rxe5. -----
Another option is 29.Rd4:
A) 29... Rxd6 30.cxd6 (30.Rxe4 Re6)
A.1) 30... Qxe5 31.Nxe5 Bxe5 32.Rdc4 Bxd6 33.Rxc6 Rxc6 34.Rxc6 and 35.Rxa6 + - [R+2P vs B]. A.2) 30... Bxe5 31.Rxe4 fxe4 32.Nxe5 Bd7 33.Rxc8 Bxc8 34.d7, etc. B) 29... Bxe5 30.Qxe5 Qxe5 31.Nxe5 Rdc7 (31... Rxd4 32.exd4 creates a second passed pawn) 32.Rd6 and the ending looks won. -----
I think I'd play 29.Qxd7. |
|
Nov-21-13
| | agb2002: After 29.Rd4 Rxd6 30.cxd6 Black equalizes at least with 30... Bb7. For example, 31.Rxc8 Qb1+ 32.Kh2 Bxc8 33.Bxg7 Kxg7 34.d7 Bxd7. |
|
Nov-21-13
| | doubledrooks: I went for a big tradeoff with 29. Qxd7 Bxd7 30. Rxd7 Rg8 31. Rxg7+ Rxg7 32. Bxg7 Kxg7 33. c6 Qe8 34. c7 Qc8 35. Ne5 Kf6 36. Nd7+ Ke7 37. Nb6 |
|
| Nov-21-13 | | WoodPushkin: Greetings: 31. c6 was the real puzzle. Also not caring about getting material back and chasing Black queen. Go for more...! JAH Love |
|
Nov-21-13
 | | LIFE Master AJ: 29.Qxd7 and 31.c6! should wrap things up nicely ... (I think). |
|
Nov-21-13
 | | kevin86: White clears the way for the passed pawn. |
|
| Nov-21-13 | | mistreaver: Thursday. White to play. Medium. 29?
In this one the queen begs to be sacrificed:
29 Qxd7 Bxd7
30 Rxd7 Rg8
31 c6 Kg6
32 Rxg7 Rxg7
33 Bxg7 Kxg7
34 c7
1-0
time to check. |
|
| Nov-21-13 | | NightroGlycerine: What happens if 30. ...Kg8 31. Rxg7+ Kf8? It seems like white's attack stops there. |
|
| Nov-21-13 | | Patriot: <<NightroGlycerine>: What happens if 30. ...Kg8 31. Rxg7+ Kf8? It seems like white's attack stops there.> White has a material edge even if there were no attack. Also, what does black have in terms of attack? But white does have continuing threats. I thought about 32.Rh7, threatening 33.Rh8+ and 34.Rxc8. But even without this I trust the evaluation that white is much better. |
