|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.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|
|Sep-12-07|| ||Aas: <Thean>
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.

|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 ...|
|Sep-12-07|| ||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?|
|Mar-10-11|| ||GrahamClayton: 11.♕c4 gave White and advantage in Aronin-Klaman, Leningrad 1947.|
