Some new test positions from Arasan games:

This one is pretty elementary but still cute. White can rip the pawn with Nxc5.
Check extensions are essential to see that the knight can't be touched.

[D] r1br2k1/2q1p2p/p4ppB/npp5/2n1P3/2PN1QP1/P4PBP/1R1R2K1 w - -

Here is another nice sac. After Rxc6, the Black rook on e4 can be trapped:

[D] 5rk1/1p3p1p/p1bRpBp1/4P3/1P2r3/2P3K1/1P4PP/7R w - -

This one is from a test game vs. Phalanx (always a good opponent). Arasan played
Rb8? and lost, but Qg5! wins. Pharaon finds this pretty quickly, but both Crafty
18.10 and Arasan take quite a long time:

[D] r2qkb1r/pB1n1ppp/4p3/3p4/8/1P2Pb2/P1QP1PPP/RNB2RK1 b kq -
