New Zappa Mexico II setting, dead Stockfish

[Robert Flesher]

Hello folks, I was bored last night so I thought I'd try to develope a new set of parameters to Zappa Mexico II. I want something that played like Tal on Angel Dust. So after some crazy setting and tweaking I created a super aggressive version of Zappa. It is most likely alot weaker than the default, HOWEVER, if you make a mistake, you die!

Here Stockfish is crushed in 27 moves! Let's call these setting Dissident Aggressor. Another point is that I analyzed the game with Rybka 4.0 and others and they are clueless of the dangers and do not seem the coming attack. I may be onto something here !??

Interesting, are you going to keep those settings private?

No, but they are mostly for playing against me ( humans), they are much weaker than default.

Another with against stockfish!

These setting are very surprising, in alot of games Zappa loses and looks very stupid. But in some positions it plays amazing attacks. Again I think I am on to something here. Insanity, attack from where they won't see you coming !

Here is a loss, but again look at the crazy attack Zappa gets. Few humans would withstand this kind of attacking, and this was my goal.

[yanquis1972]

great!! please share the settings. i did the same same sort of thing w/ junior but i estimate it was much weaker (~2500 elo).

[Ovyron]

No, but they are mostly for playing against me ( humans), they are much weaker than default.

I'm not going to play those settings against other engines if that worries you, but for analysis of correspondence games interesting settings are useful (for instance, I use Hiarcs Paderborn 2007 for my correspondence games instead of newer Hiarcs due to this).
