Go up one level in this thread


Of course Shredder 8/9 UCI is showing the TBs access!!!

Here you have what S8 UCI is giving:

Shredder got command stop
### from Shredder 8 (1): info nps 39657 cpuload 74 nodes 91093 hashfull 4 tbhits
1328
### from Shredder 8 (1): bestmove g1f2 ponder g4f3
best move: Kg1-f2 time: 0:02.313 min  n/s: 39.657  CPU 7.4%   n/s(1CPU): 535.905
 nodes: 91.093 TB: 1.328

As you can see there is a "tbshits 1328" info string.

This is what S9 UCI is giving:

Shredder got command stop
### from Deep Shredder 9 UCI (1): info refutation  g3f1 g4f3 f1e3 c4c7 e3d5 e6d5
### from Deep Shredder 9 UCI (1): info nps 129465 cpuload 214 nodes 273173
hashfull 12 tbhits 3809
### from Deep Shredder 9 UCI (1): bestmove g3e4 ponder c4c7

best move: Ng3-e4 time: 0:02.141 min  n/s: 129.465  CPU 21.4%   n/s(1CPU):
604.976  nodes: 273.173 TB: 3.809

There is the "tbbhits" again.

Here is the the definition for tablebasehits from the UCI specification:

' * info * tbhits <x>
		x positions where found in the endgame table bases'

So Shredder (doesnt matter wich version) is behaving according to the
specification.

To be precise you question should be "When will the UCI implementation bug in
the Chessbase GUI be fixed?"

Bye
Ingo
