Last week I left you with this position from the RJCC database. Black wins as follows:

1… Bxe4+ 2. Bxe4 Qa7 3. Rc1 (3. Kc1 Ra2 4. Bc2 Rxc2+ 5. Kxc2 Qa2+ 6. Kc1 Qa1+ 7. Kc2 Qc3+ 8. Kb1 Qxb3+ 9. Ka1 Qc3+ 10. Kb1 b3 11. Rc1 Qd2) 3… Ra1+ 4. Kc2 Qa2+ 5. Kd1 Qxb3+ 6. Bc2 Qf3+ 7. Kd2 Qc3+ 8. Kd1 Qd4+

This week something a bit different: a puzzle composed by RTCC member Richard Thursby.

It’s not difficult for White to mate in 1 move, but Richard asks you to force mate in 3 moves using the bishop on b1. You’ll have to think outside the box to solve it.

I always welcome contributions from readers of this blog, whether or not they’re RTCC members.
