Bf1 Qf1, Qg3+ Kh1, Nf2+ got the queen.
mustafiz
This one is purdy. Come on Yancey, you can write a couple of pages probably.
Bf1!!
1… Bf1 seals the fate.it threatens to win a piee perforce.
(a)2 Rxf1 Qxg2#
(b)2 Bxf1 Qxg1#
(c)2 Qxf1 Qg3+ 3Nf2+ wins Q.
1 bf1 2 Qxb qg3+ 3 Kh1 4 Nf2+
black queen goes & with it the
game
I don’t have the time this morning to look at the possible defenses for white, but Bf1 looks promising as an attempt to deflect the white queen from the guard on g3 since neither the rook nor the bishop can capture at f1 without allowing mate:
1. …..Bf1
2. Qf1? Qg3
3. Kh1 Nf2 will win the queen for knight.
What white might try to do is to force black to block up the g-file with 2.Nf7 and 3.Ng5, but I think black can win at least two pawns, unless I am overlooking something in my haste.
1. Bf1
threatening:
1. Bf1 …
2. Qxg2+ Rxg2
3. Rxg2+ Kh1
4. Nf2+ Qxf2
5. Rxf2 and wins
if
1. Bf1 Qxf1
2. Qb3+ Kh1
3. Nf2+ wins the queen
if
1. Bf1 Rxf1
2. Qxg2#
if
1. Bf1 Bxf1
3. Qxg1#
I think 1. Bf1 to pull the Queen away with 1… Qxf1 followed by ideas of 2. Qg3+ and 3. Nf2+. If the Queen doesn’t take the Bishop on f1, it looks lost also.
I think bishop f1 and it’s over…
Bf1 to deflect White’s queen, setting up Qg3+ followed by Nf2+.
kh7 followed by Bf1 not Bf1 right away because of Nf7 and Ng5
1. …. Bf1
2. Qxf1 Qg3+ (2. Bxf1 Qxg1#)
3. Kh1 Nf2+
4. Qxf2 Qxf2
Black has a Queen in exchange for Knight & Bishop.
I think 1. …Bf1
if Qxf1 then 2…Qg3+ with next Nf2.
What can white do ?
This is a triple fork situation.
First the knight goes to f2 setting up the fork.
1…. Nf2
2.QxN QxB check
forking the King, Queen and Rook
if K goes to h1
then QxQ wins
I don’t see a clear win, but it’s very possible I’m missing something.
1. …Bf1
2. Nf7+ Kh7
3. Ng5+
If 3…Qxf7 or 3…Pxg5, then white answers 4. Qxf1 defusing the threat. So instead:
3. …Nxg5
4. Pxg5 Qxg5
5. Qxf1 Qg3+
6. Kh1
I am late here, but just want to point out that the puzzle is not properly solved yet.
Bf1 is of cource not answered with the suicidal Qxf1, but with Nf7+, inviting to exchange pieces.
1. … Bf1
2. Nf7+ Kh7 (Qxf7 is just exchanging)
3. Ng5 Nxg5 (hxg5 Bxf1 is pinning g5 pawn)
4. Qxf1 (not Bxf1 Nf3)
and black needs to move his knight, but where?
I don’t see the winning line, but anyone who sticks to Bf1, should try and solve it from here…
PS
I tried to look up the actual game, but was not able to find this Sadzikowski among the participants in B18, Albena.
Could perhaps blogmaster give us the correct answer to this puzzle?
Hi Susan Polgar,
Well,already others had discussed the best possible move for this puzzle. – nothing to add further.

pht,
In case you do return to this thread, I did look at this in more depth yesterday, but basically had to conclude that were no knockout punches for black. I think, sometimes, our expectations for these problems of clear cut tactics winning pieces, or giving mates is a bit unrealistic as we all do know that tactics sometimes win pawns- the advantage of which may take 20-30 moves of careful technique to bring home in victory.
For the problem at hand, I agree with you 100%- white’s best reply is likely Nf7:
1. …..Bf1
2. Nf7 Kh7
3. Ng5! hg5
Where I begin to disagree with you- I think hg5 is stronger than Ng5 for black. Continuing:
4. Be4
Hard to distinguish these lines. I think white can play Bf1, Rf1 here equally well since black will still capture at b2. I prefer Be4 just remove the knight who seems more a thorn to me than the bishop at f1. Of these alternatives, the one that bears the most interest is the capture with the rook at f1: [4.Rf1 Qb2! 5.Kh1 (or 5.fg5?! Rg5 6.Rg1 Qe5! 7.Kh1 Ng3-+) 5. …Qc2 6.Be4 Qe4 7.Kh2 Rc8 maybe? Speculative at this point, but black seems to be up two good pawns here with some pressure on the white king]. Continuing:
4. …..Qb2
5. Bg2 Bg2
6. Rg2 Qf6 and black is again up two pawns.
If there is a hammer blow in this position, I am missing it completely. It is either really, really good, or doesn’t exist.
