Hello, Josh Levine here. First off, as a new user to the CCC I need to say, I LOVE IT. This is the best thing I've found yet. Now on to business. I have a program (Saboteur) which I introduced earlier. I have strong suspicions that the hash table(s) are not storing information properly. There was a thread here a while ago that I noticed where people were talking about mate bounds and the position /p/P5p/7p/7P/4kpK/// w I am wondering how many hash table hits people get on this position and how many nodes (per iteration. here's mine: score: 1020, nodes: 626, depth: 5 Best: f2 Kg2 Ke2 Kh1 f1=Q Kh2 score: 1020, nodes: 1112, depth: 6 Best: f2 Kg2 Ke2 Kh1 f1=Q Kh2 Qb1 score: 1150, nodes: 5066, depth: 7 Best: f2 Kg2 Ke2 Kh1 f1=Q Kh2 Qf4 Kh3 Qg4 Kh2 Qxh4 score: 1166, nodes: 16691, depth: 8 Best: f2 Kg2 Ke2 Kh1 f1=Q Kh2 Qf4 Kh3 Qg4 Kh2 Qxh4 Kg1 score: 1166, nodes: 77578, depth: 9 Best: f2 Kg2 Ke2 Kg3 f1=Q Kh2 Qf4 score: 1166, nodes: 193026, depth: 10 Best: f2 Kg2 Ke2 Kg3 f1=Q Kh2 Qf4 Kg2 Qf2 Kh3 Qf4 Kh2 Score: 9999988, Time: 59.996, NPS: 29329. nodes: 1759648, depth: 11, table use: 30716 Best: f2 Kg2 Ke2 Kg3 f1=Q Kh2 g5 h4xg5 Kf3 Also, how do I stop the hashtable from truncating the PV? I have tried lookng up best moves from the hashtable when displaying/using the PV, but my threading model doesn't really allow for that in a game situation (ugh...). Thanks for any input :) Josh Levine
