Ivanhoe-T Ghost2 x64 vs Rybka 3 x64

This is the first time that my testing of Ivanhoe in longer Time controls has proven to show Ivanhoe much stronger. Previous attempts have shown the engine only equal in longer time.

Good news this engine appears to be much stronger in long time controls!

Time Control 15' +1' Hash 512 both engines, 10 move book both sides. ponder off,

Ivanhoe-T Ghost2 x64 5 wins 7 draws and 2 losses. +75 elo.


I am continuing to test to see how the engine performs after more games are played but so far the results from these games shows remarkable play better than previous Ivans. Will see if this really hold true in the long run.

here is my result thus far. With same hash, open book and settings and no ponder and same time control of 15' 1".

Ivanhoe-T Ghost2 x64 8 wins 15 draws and 3 losses. +67elo over Rybka3.

This is the best engine on long time controls from the Ivan family of engines thus far. Enjoy!

This is time control 1' 0" bullet.

Its Ivanhoe-T Ghost vs Ivanhoe-T Ghost2

Looks like a dead even match in bullet chess

Ghost 1 vs Ghost 2, Блиц:1' 0


1 IvanHoe-T Ghost +4/=36/-4 50.00% 22.0/44 0.00
2 IvanHoe-T Ghost2 i7 +4/=36/-4 50.00% 22.0/44 0.001+0, 4 ядра. Равны.


That is 4 wins 4 losses and 36 draws for both engines. Of course one of the engines is the I7 engine which should be slightly better since it can scan postions a little faster.

Also just to clarify. Both engines using 8 Cores on I7 processor. No ponder.

After 35 games same tournament Ivanhoe-T Ghost2 x64 9 wins 3 losses 17 draw. total of 29 games. +72 elo over Rybka

Here is the last game 197 moves with a win for Ivanhoe!!! It is the longest games I have ever seen played in my test tournaments. and here it is Enjoy! This is rather long sorry.

I would highly doubt that it is weaker in blitz. Although there maybe some variations in the way it scores from game to game or tournament to tournament. Its like having Rybka playing Rybka and having one of the rybkas actually playing 10-30 elo better. There is such a thing as margine of error. It really takes hundreds of games possiblely thousands to establish one engine over another being better. Even in my case of testing ghost2 vs Rybka3. But for me its the first time that ivanhoe has shown promise in playing good at long time controls. All previous attempts to play ivanhoe and other versions of it has failed to play better at long time controls.

highly doubt ,,cheeky sod
doubt this
98 games jazztimes ivan vrs testers ghost
phenom 965 , hash 512 ponder on , same books
blitz 3+1 fritz 11
jazztime ivan +44 =36 -18

as i wrote it may well be better in long time contol and is a very good engine
but

I am putting that to the test and yes 100 games may not really be enough like a was saying before. running a tourney now agasint his b4 mod to see what happens in a 3 +1
