These positions were from the end of a 15 1 game, and Arasan was having to blitz. In the 2nd position, Arasan switches and sticks to Kc3 after about 16 seconds with or without tablebases, and gives a zero score after 45 seconds (I only have 5-man tablebases). But it didn't have 16 seconds in this game. This is the non-tablebase output: ply 1. Rg1+ 0 seconds. score: -0.67 7 nodes. ply 1. Rg1+ 0 seconds. score: -0.67 22 nodes. ply 2. Rg1+ 0 seconds. score: -0.91 105 nodes. ply 3. Kc3 0 seconds. score: -0.84 1239 nodes. ply 3. Kc3 0 seconds. score: -0.84 1269 nodes. ply 4. Rg1+ 0 seconds. score: -0.95 4243 nodes. ply 4. Rg1+ 0 seconds. score: -0.95 5596 nodes. ply 5. Kc3 0 seconds. score: -0.84 15369 nodes. ply 5. Kc3 0 seconds. score: -0.84 21716 nodes. ply 6. Kc3 0 seconds. score: -0.73 55376 nodes. ply 7. Kc3 0 seconds. score: -0.84 172368 nodes. ply 8. Kc3 0 seconds. score: -0.61 472964 nodes. ply 9. Rg1+ 1 seconds. score: -0.27 1161054 nodes. ply 9. Rg1+ 2 seconds. score: -0.27 1495097 nodes. ply 10. Rg1+ 4 seconds. score: -0.28 3395123 nodes. ply 11. Kc3 16 seconds. score: -0.02 11293567 nodes. ply 11. Kc3 19 seconds. score: -0.02 13630877 nodes. ply 12. Kc3 45 seconds. score: +0.00 31933032 nodes. ply 13. Kc3 114 seconds. score: +0.00 79265656 nodes. The 1st position (find Rb6) is a lot harder for Arasan. --Jon
