1.Qf3 with the idea of 2.Qc3# doesnt work after 1. .. Kb4 2. Qc3+ Ka4 and only perpetual.
But 1.Qb1 with the idea of 2.Qb5+ Kd4 3.Qd5# seems to work.
1.Qb1 Kd4 (Qg8 (to protect d5) 2. Qa2+ +-)
2.Qb3 Qxe4+
3.Kd6 Qg2
4.Qc3+ Ke4
5.Qc6+ +-
I guess 1. Qb1 wins… Threats checkmate in 2. If 1. … Qf7 (to defend the d5 square) then 2. Qa2+ wins the queen.
Morsa,
what if :
1.Qb1 Kd4
?
there is one more tricky variation.
1.Qb1 Kd4 (Qg8 (to protect d5) 2. Qa2+ +-)
2.Qb3 Qxe4+
3.Kd6 Qa8
4.Qe3+ Kc4
5.Qc3+ Kb5
6.Qb3+ Ka6
7.Qa4+ Kb7
8.Qb5+ Ka7 (8…Kc8 9.Qd7+ and Qc7#)
9.Kc7 +-
Tobe
”1.Qb1 Kd4
2.Qb3 Qxe4+
3.Kd6 Qg2”
3….Qa8 seems black eludes…well, for the moment.
If:
1. Qc1+ Kd4??
2. Qc3+ Kxe4 forced
3. Qc2+ and black can resign.
Fritz showed me the correct answer (not in the variation I present). I would not have gotten this one. No I won’t tell you the answer. Figure it out yourself please.
