| Sep-12-07 | | HelaNubo: <wouldpusher: <17. c4 Rxb2 18. Qd3> That last move was a bad one, as 18. ... Rb3+ wins. Instead, 18. Nd4 Qxd4 18. Ba5. At least that's without a machine to do the analysis.>
17. c4 Rxb2 18. Nd4 Qxd4 19 Ba5 then 19... Rxe2 is check, and mate at the next move. |
|
| Sep-12-07 | | Fezzik: I was worried about 17.Qe7! until I saw the Rook sac idea from yesterday. This time, the sac occurred on b1, but the idea of attacking the open file with gain of tempo remains the same. This was a good way to combine puzzles, cg.com!

|
| Sep-12-07 | | vibes43: I'm short on time tonight. Saw no good initial sacs so settled on ...Ba3 w/o seeing all replies like Qe7. Good puzzle. |
|
| Sep-12-07 | | skemup: Rb1+! i missed it agrhhhhh... |
|
| Sep-12-07 | | RandomVisitor: 16.Bxb4! was necessary in the game, then 16...Qxb4 17.c3 Qf4+ 18.Qd2 Nd5 19.Nxf5 or 19.Qxf4 and white has a nice advantage. |
|
| Sep-12-07 | | King mega: found this one rite. |
|
| Sep-12-07 | | ianD: Got this one. B2 the oviously weak square the rest was elimentary |
|
| Sep-12-07 | | Marmot PFL: Easy puzzle with common R+B attack. I would have thought that 0-0-0 was too risky here (without checking RV's analysis of 16.Bxb4, which is obviously better than the move played). |
|
| Sep-12-07 | | Sydro: Not so hard but it looks quite pretty when you get to sacrifice a rook just to get your Queen one move extra that leads to checkmate. |
|
| Sep-12-07 | | TrueBlue: I found it hard. I got Ba3, but not before considering Bxd2 followed by rook sacrifice on b2. Attack on the b2 square was what I was trying to do in both lines. Problem was that white is well developed and black's moves need to be forced. |

| Sep-12-07 | | TheaN: 3/3
I'm giving a full point as I noticed that some way of counterattack would be futile to either a sac or just a surrounding by Black. I admit, upon clicking the game I had not yet played Qe7, but I would've played this within a few seconds. 16....Ba3 is forcing.
17.bxa3 Qa3#
17.c3 (or c4) Bxb2+ 18.Kc2 Qxf5+ and Black wins.
17.Bc3 Qxc3 wins.
17.Ba5 Bxb2+ 18.Kb1 Bc3+ 19.Kc1 Qa3#.
17.Qe7 as in game. Probably the best reply, but not that hard to refute. |
|
| Sep-12-07 | | Tactic101: Wasn't too hard. But I have to admit that Qe7 wasn't a move I was expecting. But Bxb2+ was the point we played Ba3 in the first place. |
|
| Sep-12-07 | | kevin86: I answered this one. It looked like Ba3 was virtually automatic-the bishop is immune to capture and guarding b2 is problematic at best.The rest goes on wheels. Also,an urgent move is called for since white is close to setting up a smothered mate with his queen and knight. |
|
| Sep-12-07 | | xKinGKooLx: 3/3. Going well so far.
This was very a simple puzzle - I got it quite quickly. 16. ...Ba3, in my opinion, was the ONLY good move for Black. |
|
| Sep-12-07 | | YouRang: I found 16...Ba3 after a few moments. Like <kevin86> says, it's easy to see that it can't be taken, and that it presents a strong threat, so it's seems to be an "automatic". Also, it prevents 17. Bc3 (c3 is unguarded because the b-pawn is pinned). The hard part is figuring out what white's response would be. I didn't consider 17. Qe7, but I noticed that 17. Qe5 and bishop moves (i.e. give the king room at d2) all fail. |
|
| Sep-12-07 | | znprdx: I almost chose 16....Bc3 to inhibit a queen exchange with Qe5. Finding Ba3 was sweet - but like many admitted, I didn't consider the resourceful Qe2 (remniscent of last weeks Qc7 in Kupreichik - Radulov) – with the direct mate threat. This was a puzzle within a puzzle - having to see the pretty 7ply Rb1 from scratch - unlikely, but hopefully once the time came:) Nice lesson |

17.c3 (or c4) should be countered with Rxb2 which gives about a 15 pawn lead to black, vs. about 2 pawns which 17... Bxb2+ gives. Whites best reply is 17.Qe5 which after 17..Qxe5 18.Rxe5 Bxb2+ 19.Kb1 Bxe5+ is rated to about a 6 pawn lead to black. Courtesy of fritz.. |
|
| Sep-12-07 | | patzer2: For today's puzzle solution, Black whips up a mating attack against the weak Queen-side castled position with 16...Ba3! However, the speculative 15...Qc5?! which helped set it up was probably premature, since 16. Bxb4!  holds with advantage as pointed out by <RV>. |
|
| Sep-12-07 | | zb2cr: Found it. Took me about 45 seconds. Good thing, since I'm in a rush ... |

 | | fm avari viraf: I think, White was totally unaware of Black's cute little combination of 16...Ba3 otherwise, he would have played something else to avert such a disaster for e.g. 16.Bxb4 Qxb4 17.c3 etc. which would be better. |
|
| Sep-12-07 | | Monkey King: Another 1 move solution. This weak is Jl |
|
| Sep-12-07 | | mworld: 3/3 - although, i wish i saw it as far in advance as Nisman. |

| Sep-12-07 | | Crowaholic: <RandomVisitor: 16.Bxb4! was necessary in the game, then 16...Qxb4 17.c3 Qf4+ 18.Qd2 Nd5 19.Nxf5 or 19.Qxf4 and white has a nice advantage.> Ouch. At first I thought the following continuation of your 19. Nxf5 line was ok: 19. ..Rxf5 20. Qxf4 Nxf4 21. Re5 Rbf8?? and there goes the f5 rook. Accursed back rank. Anyway, after 21. ..Rxe5 22. Nf7+ Kg8 23. Nxe5 Nxg2 24. Rd7, White definitely has a favorable endgame. <wouldpusher: 18. Nd4 Qxd4 18. Ba5.> Then 19. ..Rd2+ 20. Kb1 Qb2#. 19. ..Rxe2+ works too, but ..Rd2+ is more humiliating. ;-) |
|
| Sep-12-07 | | unixfanatic: It seems White would have been a lot better off after 16. Bxb4. Then 16. ... Qxb4 17. c3 and after whatever Black does next 18. Nxf5; doesn't this give White a better position? |
