Bird's opening - featuring mate with Bishop and Knight. | ||||

1... c5 2. Nf3 Nf6 3. b3 d6 4. Bb2 e6 |
Transposition to some closed Sicilian is quite common. | ||||

Both e6 and g6 does not feel right. | ||||

The least of two evil things I guess. | ||||

66. Nxd3 |
Mate must be done within 50 moves from this position. The aim is do drive the opponent king to the side and toward the corner with the bishops color; h1 or a8 in this case. | ||||
