1. B:f7+ and it looks like Black can’t afford to risk 1…K:f7 2. Qb3+ Kf8 3. Ng5 Ne5 (the only move) 4. Nc4 (seems stronger than merely 4. B:e5 winning the piece back but allowing 4…d5)
The best try for Black is to give back the piece right away with 2. .. Nd5, but then White is still winning because she still has a great attack, and has the time to do a build-up to an overwhelming position. For instance, 3. Qxd5+ Re6 followed by these moves for White: Nc4, Rfd1, e5, Rac1.
1. Bxf7+ Kxf7 (or suffer the loss of quality + pawn) 2. Qb3+ Kf6 (Kf8? Ng5! looks like undefendable mate on f7) 3. e5+ Kf5 (Nxe5 Bxe5+ will only delay) Seems the poor king will be mated by bishops and kingside pawns.
I don’t have a lot time for this today, but I might look at a sacrifice at f7:
1. Bf7 Kf7 2. Qb3 Nd5 (other moves much worse) 3. Qd5 Re6 and white has an edge, but I don’t have time to look to see if white has something better than this.
1. Bxf7+!! Kf8/Kh8
2. Bxe8 & White is exchange up 1-0
1. Bxf7+!! Kxf7??
2. Qb3+! Kf6
(If 2. … Kf8? 3. Ng5 XXX 4. Qf7+ checkmate)
3. e5+ Nxe5/Kf5
and White will checkmate in next 3-4 moves!
Can somebody help me understand the calculation for TB1, TB2 & TB3 in a Swiss tournament?
1.Bxf7+ Kxf7 2.Ng5+
1. B:f7+ and it looks like Black can’t afford to risk 1…K:f7 2. Qb3+ Kf8 3. Ng5 Ne5 (the only move) 4. Nc4 (seems stronger than merely 4. B:e5 winning the piece back but allowing 4…d5)
1. Bxf7+ is the correct and obvious try. After 1. .. Kxf7 follows 2. Qb3+ and if Black tries the obvious 2. .. Kf8 3. Ng5 and mate next move.
2. .. Kf6 is also bad. 3. e5+ Nxe5 (3. .. Kf5 4. Qf7+ Ke4 (4. .. Kg4 5. h3+ Kh5 6. Qf4 Nf5 7. g4#) 5. Rae1+ Kd3 6. Qc4#) 4. Bxe5+ Kf5 5. Qf7+ leads to a quick mate.
The best try for Black is to give back the piece right away with 2. .. Nd5, but then White is still winning because she still has a great attack, and has the time to do a build-up to an overwhelming position.
For instance, 3. Qxd5+ Re6 followed by these moves for White: Nc4, Rfd1, e5, Rac1.
Could it bee something like:
1. Bxf7+ Kxf7 (or suffer the loss of quality + pawn)
2. Qb3+ Kf6 (Kf8? Ng5! looks like undefendable mate on f7)
3. e5+ Kf5 (Nxe5 Bxe5+ will only delay)
Seems the poor king will be mated by bishops and kingside pawns.
After
Bxf7ch Kxf7
Q-n3+ K-f8
N-g5
Black has no good defense against Q-f7#
I don’t have a lot time for this today, but I might look at a sacrifice at f7:
1. Bf7 Kf7
2. Qb3 Nd5 (other moves much worse)
3. Qd5 Re6 and white has an edge, but I don’t have time to look to see if white has something better than this.
