Mar-08-07		DKWRRT: Ok I am a beginner but why does Rxf1 and Bxf4 result in check and win the game. As I see it the f3B or the Q could both kill f3. I have only been playing about 6 months.

Mar-08-07		periscope: 25. Qxf1 is better than the rook but it still loses as black is then left with a mop up after 25. ... QxB, 26. QxQ,RxB and then the attrition begins.

Mar-08-07		Rubenus: Are there any people who noticed that it is 'rook sacrifice week'? Knowing that, I saw the first move at the first glance but I wasn't sure about the continuation, Nd2, Rxf3, Bxe4 were all moves I considered but I didn't see Ne3. Indeed one of the harder Thursdays.

Mar-08-07		micartouse: I definitely screwed this up, but I came close and looked at all the right ideas after a good 20 minutes or so. I hallucinated at the end though and instead of 24 ... Nxf1! I thought 24 ... Rxf3? followed by ... Bxe4 which doesn't work at all. Bad visualization.

Mar-08-07		MostlyAverageJoe: <ravadi: <MostlyAverageJoe: <ravadi:What if white plays 20.Bf2?> Bad things happen after 20 ... Rxh3 21. gxh3 Qxh3, threatening heavy damage after 22 ... Qg4.> 23.Bxg4 isn't it?> OOPS. I knew I should've had a good sleep first; I missed writing out one turn when doing a brain dump. The line I had in mind was: 20 ... Rxh3 21. gxh3 Qxh3. 22. Kg1 Rxf3, threatening heavy damage after 23 ... Qg4. Add 1 to the move numbers in the rest of my description.

Mar-08-07		micartouse: Welcome <DKWRRT>. I think the answer is 26. Qxe4 Qxf1+ 27. Bg1 Qh3+ 28. Bh2 Rf1#. And 26. Bxe4 Rxf1+ 27. Qxf1+ Qxf1+ 28. Bg1 Qxf3+ with a queen vs. bishop easy ending. So Black has this one wrapped up. This is an advanced combo; many strong players here couldn't get it all.

Mar-08-07		MostlyAverageJoe: <micartouse: Welcome <DKWRRT>. I think the answer is 26. Qxe4 Qxf1+ 27. Bg1 Qh3+ 28. Bh2 Rf1#> Nope, there is still white Bf3 in the way. But 28 ... Qxf3 forces queen exchange and black has a rook and lots of pawns against a bishop and a couple of pawns. You're mostly right about the other line, except for Qf3+ (there's a white bishop on e4). Queen against 2 bishops, with pawn advantage, is good enough, though.

Mar-08-07		zb2cr: Took me about 2 minutes to find the key line, but I believed that White would play 25. Qxf1, Rxf3. I did consider that if 25. Rxf1, Bxe4 would decoy away the Queen or Bishop.

Mar-08-07		builttospill: I'm giving myself credit for this one, since I got every move, but for some reason I forgot to examine 25. Rxf1 and only checked out Qxf1.

Mar-08-07		greensfield: Give up a Rook for two Pawns. Then a Knight fork gains a Rook. White has two options to capture the Knight 25. Qxf1 or 25.Rxf1. Either one leaves Black in a strong position, I'm not sure that the one played is the best

Mar-08-07		playground player: Had it all the way... See, I'm getting smarter already.

Mar-08-07		YouRang: I pretty much got it. The rook sac seemed to be the only avenue for attack, and the rest followed naturally. I didn't see the subtlety of 25. Rxf1 Bxe4. For some reason, I expected 25. Qxf1 Qxf1+ with winning black endgame 3 pawns up.

Mar-08-07		uuft: Yeah, Baby!! Four in a row! And I don't give a tiny rat's behind 'bout what happens after move 24., like, in a zillion years! Sweeeet... (((:::

Mar-08-07		bramdas: I actually don't get this one..what am i missing in this line.. .. Rxh3+ 22.gxh3 Qxh3+ 23.Bh2 Ne3 24.Qe2 Nxf1 25.Rxf1 and then does the following line work or am i missing something? Bxe4! 25.Rxf1 Bxe4 26.Bg2 Rxf1+ 27.Qxf1 Bxg2+ 28.Qxg2 Qxg2+

Mar-08-07		simsan: <bramdas> A drastic improvement to your line is 25. Rxf1 Bxe3 26. Bg2? Bxg2 27.Qxg2 Rxf1 (winning the queen)

Mar-08-07		Themofro: Missed the ending of Rxf1 and Bxe4 but got the rest no problem.

Mar-08-07		pggarner: Missed it; couldn't put the knight fork and the rook sacrifice together. I see that 25.Qg2 doesn't help White either, as after 25....Qxh2+, 26.Qxh2 Nxh2, 27.Kxh2 Rxf3 White is down a bishop plus the three pawns.

Mar-08-07		simsan: I guess my own analysis started with immediately seing the fork on e3. But also acknowledging that it was prevented by the bishop on g2. Since diverting the bishop didn't help maybe I had to get started in some other way. I then realized that taking with the R and Q on h3 would force the bishop to h2, thus allowing the fork. I also determined that white would have to respond by moving his queen, and that it would have to move to e2 in order to maintain protection of the bishop on f3. OK, so I get to take the rook, but white can retake with the rook, and I will still be down a piece, and he will have protection for his bf3 (or so I thought). Sadly, at this point so many pieces had moved away from the diagram position that I was having difficulties seeing Bxe4 in my head. And without seeing Bxe4 all you really have achieved is winning three pawns and an exposed king for a bishop. At my level that is a rather unclear position. I don't feel I solved this.

Mar-08-07		fm avari viraf: I think by move 21...Rxh3+ White is completely lost. But I would not prefer White's 15.f4 so early. Only after developing the Black Bishop to d2 & to e1 preparing the King side def. & then at appropreiate time play the text move.

Mar-08-07		mravikiran: nah... didnt get it this time... I am not good these days. Out of form

Mar-08-07		TheBB: I didn't get it. There were a trillion candidate moves to consider... So many typical and promising sacrifices. My brain couldn't handle it all. :(

Mar-08-07		aazqua: Sort of obvious but also extended. Once you know it's a puzzle the line isn't really challenging at any point.

Mar-08-07		kevin86: I missed this one,because I couldn't get the move order right. Black must force Bh2 in order to enable his penetration at e3. If Be3 is played too soon,white gets a flight square for his king and neutralizes the rook sac.

Mar-09-07		Fisheremon: From the puzzle it's clear that 21.Rc1? Instead 21.Qe2!? could save. A very alluring possibility for Black was 18...g5.

Mar-10-07		avidfan: Severe overloading of white queen and pin of B/f3 in the final position if 25.Rxf1 Bxe4 calls for White's resignation.
