1..Bxf2+ looks strong. As the white knight must not take – or mate on g2 – 2.Kxf2 Qxh2+, which looks like game over to me.
1… bxf2+
2. kxf2, bxe4
now if
3. qxe4, qxh2+
4. ke3 or kf3, rxg3+ wins
(if 4. qg3 instead, then 4…rf6+ wins the queen).
3. rxe4, leaving room for ke2 offers some resistance. but
3… qxh2+
4. ke1
now …rf6 or …rxg3 still should win, because white king is totally exposed.
errata (to previous comment/post):
3. rxe4, leaving room for ke1 not ke2.
1…Bxf2+
2. Kxf2, (if Kh1, then Rxg3 with mate coming on g2)
2…Qxh2+ with an easy win to follow
Phil, if
1. … Rxg3+
2. hxg3 Bxf2+
3. Kxf2
then what? I can’t see a way to turn the king chase into mate…
what about:
1.Rxg3+ hxR
2.BxN QxB
2.Qxg3+ Kh1
3.Bxf2(threating 4.Qh3#) Qg2
4.QxQ+ KxQ
5.BxR and white is on top.
–henryk
well, now looking at it now,
white does have 5…Qa8+..but I’m not sure if black can get out of that one.
1.Rxg3+ hxR
2.BxN QxB
2.Qxg3+ Kh1
3.Bxf2(threating 4.Qh3#) Qg2
Adjusting move numbers a bit:
1…Rxg3+
2.hxg3 Bxe4
3.Qxe4 Qxg3+
4.Kh1 Bxf2
… White seems to have a perpetual with either 5.Qc4+, 5.Qd5+, or 5.Qa8+.
well, I guess then
1…Bxe4
2.QxB
(2.RxB Rxge+ 3.hxg3 Qxg3+ 4.Kh1 Bxf and threating mate with 5…Qh3 or Qg1 wins)
2….Bxf2
3.KxB (3.Kh1 BxR wins) Qxh2+
4.Kf3 (e3) Rxg3+ wins
hopefuly I’m right this time,lol.
well, I guess then
1…Bxe4
2.QxB
(2.RxB Rxge+ 3.hxg3 Qxg3+ 4.Kh1 Bxf and threating mate with 5…Qh3 or Qg1 wins)
Not so fast, cowboy. 5.Qc4+ draws.
…. bxf2
kxf2 qxh2
ke3 bxe4
(qxb rxg3 and kxb rg4+)
seems good
The Bxf2+ line doesn’t look all that sound either; see:
1. … Bxf2+
2. Kxf2 Qxh2+ (2. Kh1? Rxg3!)
3. Ke3 Bxe4
4. Qc4+ Kh8
5. Qe2! and now I can’t see how black can win. 5. … Qxg3+ 6. Kxe4 Qxc3 is the best I can see with a two-pawn advantage.

1. … Bxf2+
2. Kxf2 Qxh2+ (2. Kh1? Rxg3!)
3. Ke3 Bxe4
4. Qc4+ Kh8
5. Qe2 Qxg3+
6. Kxe4 Qxb3
The computer gives this a -8 score for white. It’s not entirely clear to me why, as there seem to be many variations.
Maybe one line is something like this:
1. … Be5 (preventing white Q from checking)
2. Re2 h5
3. Qe1 h4
4. Qf1 hxg3
5. QxQ gxf2
6. Kf1 Bc4+
7. Re2 Rg1++
There seem to be other defenses for white though, like 2. Nd2 (planning Nf3 then attacking the pawn at h4), or maybe 2. Nb-c5
1.) … Rg5
”1.) … Rg5”
1…Rg5?
2.Qxb7 Rh5
3.Nbd2 Qxh2
4.Kf1 Qh3+
5.Ke2 Qg4+
6.f3 Rh2+
7.Kd1 and Black is losing.
1. … Be5 (preventing white Q from checking)
2. Re2 h5
3. Qe1 h4
4. Qf1 hxg3
5. QxQ gxf2
6. Kf1 Bc4+
7. Re2 Rg1++
Not that I’ve never slipped on a typographical error here, but this line’s got me totally baffled.
True that the above line is a bit(…) weird.
In the line, given above,
“1. … Be5 (preventing white Q from checking)
2. Re2 h5
3. Qe1 h4
4. Qf1 hxg3
5. QxQ gxf2
6. Kf1 Bc4+
7. Re2 Rg1++”
the commenter meant 1. … Bd5.
The idea is that Black still has his pieces pointed at the king. Let’s take a little longer and bring up a pawn to attack.
Some other candidate moves for white other than 2. Re2 are 2. Rd1, 2. Nbd2 and 2. Nbc5
the commenter meant 1. … Bd5.
Even if you’re right about this, you’re still overestimating my intelligence. Several of his subsequent moves look very weak, and a few are illegal.
