Hello Roger,

Just a wild guess. When I run v4.00 using InBetween, this is what I see upon typing uci:

ChessBrainVB by Roger Zuehlsdorf
uci

id name ChessBrainVB V4.00

id author Roger Zuehlsdorf, Germany

option name Threads type spin default 1 min 1 max 64

option name Hash type spin default 128 min 1 max 1400

option name Clear Hash type button

uciok

Maybe those blank lines are responsible for the problem.

BTW, does it still support WinBoard?

I have multiple machines, in the one which I have BitDefender Endpoint Security, it automatically deletes all the VBA from Excel by flagging them as virus.

Perhaps, the code can be shared with BitDefender to whitelist it.

Can you build a Korean chess engine?

Hello,
Would you please make an android version?
Thanks!

In an ongoing 40/40 test ChessBrainVB 3.70 64-bit lost practically every game with Black due to stalled connections or disconnects. Out of 30 participants, ranging from Xiphos and Arasan down to GreKo and Marvin, this is the only engine to have any problems in this test.

One example out of 19:

If you set up a board and then put the computer in check-mate it throws an error.

It's sad that it's not possible to compile the newest version on Android and Linux devices.

Just wondering if you're planning on implementing ponder? I run all my tournaments with 1 thread + ponder, and it really helps at short time controls like 1m + 1s or 2m + 1s.
I noticed that ChessBrainVB and for example Halogen lose quite some performance when going from 1m + 1s to 2m + 1s, compared to the pondering engines. It's like it doesn't have a huge effect at 1m, but at 2m is like some sort of sweet spot and it helps a lot.
