Thanks Vass! I have the free ones, I guess since I want to try Aquarium, I'll go for it with Houdini 3. As for the rest of the commercial ones, I think I have enough anyway!  Cheesy

Well maybe someone will correct me, but White's win in #54 looks to me like something that most strong players would consider.

Maybe, you would have to see a3 (threatening to trap the queen) to force the queen back, and then Qe1, and then evaluate the position correctly.
However, like most tactical positions it is a lot easier to see when you know there is a tactic to be found!

I agree. It is a natural sacrifice, and while I think few players would be able to determine it was winning OTB, I think many strong players would seriously consider it.

Also, checking my Rybka 4, after 13.Rxe7 c6 it needs about 3 seconds to put 14.Rxg7+ as its first choice. Although it initially evaluates it as equal, just seeing that move on top of the list would have made me nervous if I was intending to recommend this for Black.

That's impressive! My humble Houdini 1a takes fully 5.75 seconds!

Why don't you download the free 1.5a, it's pretty good?


Sorry Tony, that's the one I meant! My PC is pretty fast, so I guess we can conclude H3 is significantly better ...

So, if I were to choose only one engine, I take it that you would recommend Houdini 3. And if I have a choice of a second one, which would it be, Rybka 4? Something else? Deep Hiarcs?


Well, let's see!

One engine? - Houdini 3 (commercial).
Two engines? - ... + Stockfish 2.3.1 (free) - sometimes better in closed positions..
Three engines? - ... + Houdini 1.5a (free) - more reliable for an analysis in depth.
Four engines? - ... + Critter 1.6a (free) - sometimes better in endgames' analysis and the second best after Houdini, in fact.
Five engines? - ... + Komodo 5 (commercial) - sometimes giving some good analysis lines (ideas), different from others, because of its unique method of evaluation.
Six engines? - ... + Ivanhoe B46 (free) - just like Komodo 5.
Seven engines? - ... + Deep Rybka 4.1 (commercial) - because of pure nostalgia, maybe.. Or, just because it's good.
Eight engines? - ... + Zappa Mexico II (commercial) - because of its unique "dissident aggressor" options for solving tactical positions that Houdini 3 "tactical mode" won't solve.
Nine engines? - ... + Critter 0.90 (free) - good for some endgame analysis and closed position analysis, too.
Ten engines? - ... + Deep Fritz 10 (commercial) - once it was a great program, you know. And the most "human" engine I have ever seen..  Smiley

But, let me stop here! Otherwise I would be tempted to mention Deep Hiarcs 14, Vitruvius, Fire 2.2 xTreme and so on...but for no reason.  Undecided

By the way, one big improvement in Houdini 3 is the so-called "tactical mode".
What it means?
It means that one can prepare Houdini 3 for highly tactical positions just by checking the option "tactical mode" in the engine parameters menu before doing an analysis.
According to some testers, it solves tactical studies up to 30 per cents better (and faster) than the Houdini 3 in classical mode. These results rank the engine among the best ones in tactics.
I often try this option in my correspondence chess tries. And I can say I'm very impressed by the results, too..  Wink
Meanwhile, some testers ran matches between Houdini 3 and Houdini 3 "tactical mode". What is amazing is that Houdini 3 "tactical mode" is just a bit weaker in playing strength. Usually, engines don't play very well in tactical mode, because they're somehow "twisted" in parameters. Not Houdini 3 "tactical mode" though. Still it can win a match against any of the best engines available.  Cheesy

In Glenn's December update (on the Dutch) he originally said that 12...d5 might be a good solution to Black's problems in the 7...Qe8 8 Re1 Leningrad:

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*
Apparently he was using Rybka4, which likes Black's position. However, a subscriber pointed out that White has almost a forced win so Glenn had to quickly change his analysis!
Indeed, when I checked with Houdini3 it gives 13 Rxe7 c6 14 Rxg7+ as winning in less than a second!

I just looked at a position I had already analysed in my new book (DW-Spanish) with Houdini 3, and to my surprise it didn't find the draw that Houdini 1.5 had discovered! Roll Eyes


I'm not surprised at all..
Maybe, as a correspondence chess player, I'm addicted too much to my beloved engine ...but, if Houdini 1.5a is as faster as Houdini 3 and can reach the same ply's depth for the same amount of time...I would never even try to use the new toy called Houdini 3.  Wink
The problem is that a good analysis is taking time, too much time.. One too many sleepless nights..
And I have my own conclusions I can share. For example, I never believe Houdini 3's evaluation in a complex position if not reached at least 27-28th ply's depth.. While 1.5a version's evaluation on 26th ply's depth is almost definitive. The only problem I find in Houdini 1.5a is that its style of play is not as dynamic as Houdini 3's one. Hence the difference in ELO points..  Roll Eyes
