Black to move. How should black proceed?
Source: ChessToday.net
I think that
1. … Bxh3 wins at least a pawn. White cannot afford to take the bishop:
2. gxh3 Nf3! Threatens Rh2#, plus the queen and the knight are both hanging.
3.Qg3 Rh2+ 4.Qxh2 Nxh2 5.Kxh2 Qxe3 -+
Not quite sure how White should proceed now, but
2. Nf5+ Bxf5
3. exf5 seems logical and looks like a strong attack, however, after
3. … Ng4 Black is better.
1…Bxh3
2.gxh3 Nf3
3.Qf4 Rh2+ (Unfortunately black can not take N to divert Q because of 4.Qxf7+)
4.Qxh2 Nxh2
5.Kxh2 Qxe3
One of white’s pawns will fall immediately and black should have technical win.
sorry. It is me.
Refutation of “fajac” line:
if
1… Bxh3
2. Nf5+ Bxf5
3. exf5 Ng4 will result in a mating net (4. Qxg6 Kh8, 5. Ra8+ Qc8m 6. RxQ ++) However, if
3. exf5 Qf2 may be a better line… (e.g. 4. Rxf7 KxR, 5. pxp Nxg6 6. Bd3 Qe1+, 7. Kh2 Qe5+, 8. QxQ NxQ, 9. Be4 Rb4 (and black has pawn supremacy for a successful endgame)!
1. ……, Rf2 (white Bishop is trap)
2. Nf5+, Bxf5
3. exf5, Rxf1+
4. Kh2, Qg1+
5. Kg3, Rf3+
6. Kh4, Qf2#
2. Bd3, Nxd3 white has nothing in return
I did not let the white king to move to g1 to support the bishop because it’s worse, the queen will be in exchange for a rook
1. ……., Rf2
2. Kg1, Nf3+ losses the queen
3. Kxf2, Nxg5
2. gxf3, Rxf1+
3. Kxf1, Qxg5 Black has a Queen, Bishop and 5 pawns against Rook, knight & 5 pawns
Yesterday I had analysed something and wrote something else. After 1….. Bxh3 2.gxh3 better is
2…. Rh2+
3.Kxh2 Nf3+
4.Kg2 Nxg5 gives no option to white.
However after 1….. Bxh3 2.gxh3 Nf3 white has an option
3.Rxf7+ Kxf7 forced
4.Qf4+ followed by 5.Qxf3
Perhaps 1…… Rf2 can be countered by 2.Qg3 taking Q out of fire line.
Grunfeld Laszlo’s refutation is interesting.
We have a clear idea what white should not do.but We have no clear idea what black should do after white refuses to play 2.gxh3.
After1…Bxh3 2.Nf5+ Bxf5 3.exf5
3…. Qf2 is a bombshell.
4.Bd3 (this is o.k. N can not take it because of 4…. Qxg6+)
4….. Qe1+
5.Kh2 Nf3+
6.Kh3 Nxg5+
7.Kh2 Nf3+
8.Kh3 Qh4#
If 4.Rxf7+ Kxf7 5.fxg6+ Ke6 white may not be able to avoid mating net.
6.g7 Qxf1+ 7.Kh2 Nf3+ 8.Kh3 Nxg5+ 9.Kh4 Kf5 10.g4+ hxg4 11.g8=Q Qh3#
I’d say 1…Qb4, threatening 2…Qe1 with the threat of mate.
