It is obviusly not a new idea, but a candidate to new idea is using exactly those 4 killers, and the exact details of the rest of Rebel ordering. I use Killer-One [current ply] Killer-Two [current ply] Killer-Three [current ply] Killer-Four [current ply] Killer-One [current ply+2] When a killer causes a cut-off it win two places. When a killer is the best move (with exact score) it win 3 places. Also when the recommended move of the hashtable causes inmediate cutoff it win 3 places. At least for me it works much better than using only 2 or 3 killers in terms of time to reach depth. I don't use much other ordering though, as I get much counterintuitive things. BTW Very cool page the one of Ed. Very enjoyable. Keep going Ed! :)
