crafty19.10f has a hard time making up its mind :-)
it starts with Rxh3+
9-> 0.42 -2.24 1. ... Rxh3+ 2. gxh3 Rg3 3. Qg2 Rxh3+
4. Kg1 Rg3 5. Rd2 Rxg2+ 6. Rxg2 Bxf3
7. Nxf3 Qxf3
then switches to Rxg2
12-> 42.76 -2.50 1. ... Rxg2 2. Qxg2 Rxg2 3. Kxg2 Bd5
4. Rd2 Qg6+ 5. Kf2 Qg3+ 6. Ke2 Qxh3
7. Rc1 Qf5 8. c4 Bc6 (s=4)
then selects Bd5 patiently, with one or the other rook move next ...
16-> 161:05 -3.42 1. ... Bd5 2. Rd3 Rxg2 3. Qxg2 Rxg2
4. Kxg2 Qg6+ 5. Kf1 Bc4 6. Rd1 Qg3
7. h4 Qh3+ 8. Ke2 Bg3 9. Rd2 Qxh4 <HT>
...
17-> 285:57 -3.53 1. ... Bd5 2. Rd2 Rxh3+ 3. gxh3 Bc4
4. Nd3 Rg3 5. Nf4 Bxf4 6. Bxf4 Rxh3+
7. Qxh3 Qxh3+ 8. Kg1 Qxf3 9. Rf2 Qxc3
