Well, I think the problem with my engine may be still a branching factor or search tree size type of thing now that I see the speed of AMY and the nodecounts on one of the other engine's outputs posted here. By comparison my engine needs 14M nodes and 112 seconds to find this move. Thanks to all for the advice... I will look for bugs and play with extensions to try to improve this.
