Houdini 1.5 Gaviota Tablebases

[Pogi]

Hi!

I have the Houdini 1.5 running on Fritz 12 GUI.

My Gaviota EGTB files are in D:\My Documents\Chessbase\Gaviota

Setting the Houdini 1.5 engine parameters, I use D:\My Documents\Chessbase\Gaviota

Is this CORRECT?

Or shall I use D:\My Documents\Chessbase\Gaviota\

I do not know how to verify if the engine has proper access to the tablebases.

Thank you.

Pogi,

Using D:\My Documents\Chessbase\Gaviota should work fine.

You can test the EGTB by analyzing the following mate in 115 position:

8/k7/8/4Kn2/8/P7/8/1n6 b - - 01
You should get the result in less than a second:

Thanks for the reply. Wow! Houdart himself answering my post. Now I have something to brag about.

The tablebase seems not being loaded with the new Houdini v1.5 (i.e. the 8 cpu one). It was OK for the previous v1.5 version

Thanks

Never mind, my operation problem.

Sorry

The default cache for GTB is 64MB but it seems never go that high. I tried to change that to different value, say 300MB, but it doesn't seem to have any effect. Tried this in Fritz12 and Aerna. Thanks

Hi! Can somebody pls help me about gaviota egtb.

I also have the Houdini 1.5 running on Fritz 12 GUI.

I've set my gaviotaTBpath to D:\chess\gaviota (where my gaviota egtb is). I have only one file ( the kbnk.gtb.cp4 file) in my gaviota folder.

Then I tested houdini 1.5 with a position which I have in my gaviota egtb (k+b+n vs k) but Houdini just keeps calculating and doesnt use the egtb.

I don't know what's wrong with my set-up.

Pls help.

how about this ? D:\gtb ?

You also need to install the kqkr.gtb.cp4 file, Houdini needs to find it to know which compression level (.cp4 in this case) you're using.

what do you mean?

maybe there's no effect whether my tablebases are in there current folder or in your suggestion.
