White to move. How should white proceed?
Source: ChessToday.net
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.
