I'll try it. The only way I can see that this might happen is in a position where Hiarcs extends a lot more than I do (and it does this a lot, good or bad). As if it goes deep enough to see a trade to a 5 piece file before crafty can, yes it will find the right move. But in endgames, extensions are hard to come by (few checks, etc.) I've had a whole lot longer to tune the tb probing algorithm and deciding when/ where/how-deep to do it... I shouldn't get 'skunked' by anybody I'd hope...
