BigLion+Taktix : no more updates

Hi chess fans,
I intend not to update BigLion and Taktix anymore.
They have great bugs in
- move generator
- make/umake move
- main search (extensions, hash tables, null move, IID, PVS, pruning)
- quiescent search (hash tables, pruning)
- move ordering
- SEE
- evaluation
- bitboard rotations
- attack boards
- protocol handling

Instead, I will try a rewrite.
Maybe that will eliminate half of the major bugs.
I will preserve their styles of play and personalities.
See you next year ! (say the rewritten engines)
/Matthias.



BigLion 1.80f + Taktix 1.25f

Warning level :3
Final position: 8/7Q/k6P/6q1/P1P1K3/8/8/8 w - - 33 97
Analyze result:* {no draw found}

This is a wrong claim by BigLion because the position is on the board for
the 3rd time but not with the same color (player) to move!!

I have just fixed this bug and re-uploaded BigLion 1.80e + Taktix 1.25e.
No version change.

Hi folks,
am I very nervous because of Leo's tournament ?
I thank all other people who have BigLion/Taktix in their tourneys
(Alex, George, Günther, Patrick, David, Dmitry, Dr. Wael, Federic?, Lars, etc).
I hurriedly typed "HashKey" instead of "ChsPos->HashKey" and compiled without errors.
Now I have uploaded again.
I hope that was really last bugfix before the great rewrite.
Sorry for annoying you fast guys with slow modems.
Matthias.

Hi Alex,
your tournaments are a good reference and guide for me.
Eagerly waiting for that upcoming 90'/game+30"/move event.
Thanks,
Matthias.
