Go up one level in this thread

I'm glad you liked the Timman position. I post two more that in my opinion are
good test positions, even if quite easy to solve:

Kubbel #1,L - Study
Shajmati, 1925

[D]3k4/1p4pP/5p2/3p3q/3N4/4R3/K2PP1PP/8 b - - 0 1

1.Re3 Qxh7 2.Ne6+ Kc8 3.Rc3+ Kb8 4.Nf8 Qf5 5.e4 dxe4 6.Rc5 Qg4 7.h3 Qe2 8.Nd7+
Ka7 9.Ra5+ 1-0

Kubbel #2,L - Study
1927

[D]3b2q1/2kPp3/1p1pp3/1Pp4p/4QP2/p1P2P1P/2KPb3/5n2 w - - 0 1

1.Qa8! Ne3+! [ 1...Kxd7 2.Qc6#] 2.dxe3 Bd3+ 3.Kxd3 c4+ 4.Kxc4 e5+ 5.Kb4 Kxd7
6.Qc6+ Ke6 7.Qd5+ # 7...Kxd5 8.f5 e4 9.f4 Qg1 10.c4#!! 1-0
