Fascinating results...according to this...the "modification" makes Stockfish 1.8 TinaPA 1.01 stronger than Crab, Spoon and Tactical. What would be interesting to find out is whether this modification actually makes Stockfish increase its ELO rating.

hi Swami,

thanks for the quick STS testing. i wish this "sts-point" improvement translates to "elo-point" improvement.

regards,
chris

Any plans on a 64bit release?

The aggressiveness is too high!

I played an short engine match vs. Houdini 1.02
1-cpu vs 1-cpu and ponder ON.

After the first two variants of Nunn1 suite
Houdini won 2 games and 2 games ended draw.

Much better is this setting (only my opinion):
After first 3 games with Nunn1 suite Tinapa 1.01 won now 1 game with 2 draws.

CPU=Core 2 Duo 2.66 GHz
GUI=Fritz 10
EGTB=GUI only
Hash=128 MB, 128 MB
Timecontrol=3m + 0s
Book=Nunn1 suite

Here are the first 3 games with this settings:

In my opinion "Mobility (Middle Game)=80" (default 100) and "Aggressiveness=80" (default 100)
are much better than the default setting.

ED.

After any tests (games against Houdini) I prefer now fallow settings:
CPU=Core 2 Duo 2.66 GHz
GUI=Fritz 10
Ponder=ON
EGTB=GUI only
Hash=128 MB, 128 MB
Timecontrol=3m + 0s
Book=Nunn1 suite

Not bad game with this settings,
and btw Tinapa 1.01 used also too
a much better time management in this game:

Good played against one of the strongest Engines of the world!

DRAW ON PLAYCHESS AGAINST A FAST RYBKA 4!

(in my first game on playchess with Tinapa 1.01)

I have played with this settings, only with my core Duo 2.66 GHz and 256 MB Hash (with my account "Solist"):
Deep Rybka 4 played on a 8 core mashine - wow!!

I think that my settings are not bad. Tinapa 1.01 played very solid, and found
for defending with black interesting moves...like 18...Kf8! Nice game!

ED.

OT; well, in a way yes, no.

Tinapa is a Filipino fish delicacy. It's delicious smoked fish.

thanks to Tord, Marco and Joona for the well-commented top-notch source code/engine...

thanks also to Jim for the advice on compiling...

salamat,

There is only one line change:
Why do you think this single line change re null move reduction merits changing the name of the program? A code fork merits a name change if and when there's a significant modification of the code. This ain't anywhere close. Nevertheless, it's interesting.

OnePly is 2, I take it?

There is only one line change:

I guess we know what Tinapa 1.00 looked like then.
