... identifies pattern recognition -- which it identifies as the human chess skill, as opposed to "searching" -- as the primary element in speed chess...
Sure - pattern recognition is what humans do best. However, pattern recognition in speed chess is primarily a case of reflex response, both strategically and tactically.
Strategically a human sees that certain lines give him doubled pawns (bad thing), the opponent control of an open file (bad thing), isolated pawns (bad thing), bishops of the same colour as the squares occupied by his own pawns (bad thing)... these are all elements that will lose you the game in the long term (usually) for more or less complex reasons. However, identifying them is as simple as identifying the pattern, then avoiding it or prefering it as appropriate. It's pattern recognition with reflex response.
In tactical terms, humans use search quite a bit in any case. Where they don't, they'll see things such as the potential for a fork, pin, skewer, or the potential to create some long term positional advantage. Again, it's pattern recognition and largely reflex response.
Where the thinking comes in is in noticing rarer or more hidden patterns (which is more interesting, and takes time), and analyzing the effects of pattern combinations (more interesting - more time consuming).
The amount of patterns / combinations which are obvious will depend on the level of the player of course. However, for any player, the most interesting patterns he can cope with will not be the ones which jump out after two seconds - they'll be the ones which take some consideration / working out.
A part of me wonders at the effort to push such a crabbed definition of intelligence that "fast tactical thinking" and pattern recognition are dismissed from the sphere of intelligence altogether.
I was careful not to do that. I didn't say that it's not "thinking" or "intelligent" - just that it's not strategic (for that player), since it isn't. It does seem strange to champion something on the basis that it's "intuitive" (and therefore human) though.
Humans seem to have gone from:
"We can think abstractly and plan etc., whereas animals are just intuitive - we are really thinking."
to
"We can use intuition, wheres computers just use mechanical search - we are really thinking."
I don't see that "I'm great because I'm like a dog." is much better than "I'm great because I'm like a calculator.".
Likewise, I find that they often involve longterm thinking, but the longterm thinking seemed rather rote to me. A patient and studious, but not particularly brilliant, player, seems well-suited to the game.
Then play on a harder difficulty. You can't play on Deity without being patient, studious
and brilliant.
RTS games always seemed to me to reflect brilliance as I think of it -- I often saw extremely elegant maneuvers of a sort I never saw in TBS games and on occasion saw really creative tactical (if you insist on using the word) methods. More seldom, but still not blue-moony, I saw novel build orders.
Sure - elegant and novel
to you, but not to the player carrying them out. You don't develop some astoundingly novel tactic / strategy in five seconds during a frantic RTS session. You develop it over many games, and while thinking in between games. The actual playing of the game is mostly mechanical - it's just a display of what you know and how good you are.
If someone does come up with amazing new (to them) tactics almost every game, then perhaps they are brilliant, but that's rarely the case. Brilliance isn't something really different in any case - it's just that the brilliant person has become very comfortable with more complex patterns than we have, and so can combine them in ways we wouldn't think to. No-one pushes the boundaries of their own creativity when they need a good answer within two seconds - nearly all the time they're forced to stick with what they've done before, however "brilliant" that might seem to an observer.
If you want experienced players to come up with new and interesting (to them) strategies, they need to have time to do so. New players might develop interesting strategies during play for a short while, but that will quickly give way to repetitive combination of tried and true methods.
and my experience with RTS games is that my brain was actively engaged almost the entire time, processing a huge variety of inputs and rapidly engaging responses to them.
Sure - your brain is actively engaged. You're just not learning anything new. It's like the difference between solving a load of equations at high speed, and proving a theorem that's new to you. The high speed equation solving needs intelligence (in that you must have been intelligent to learn the skill), and needs mental agility. It'll also require constant intense mental activity. However, it's still mechanical, and you're unlikely to do anything that surprises you.
If you're proving a new theorem, there is nothing like the same level of intense mental activity. However, there is a lot more novelty in the ideas and concepts you'll attempt to combine. There is also a much higher chance that you'll learn something new - even if you don't prove the theorem.
TBS games never seemed to engage my brain the same way...
That's the point really - they engage the brain in a different way. They don't give you constant, intense activity, but they do provide novel thought processes even for experienced players.
I'd say that an RTS / speed chess is most fun for players of similar ability who don't know each other's game - or for players who are just learning a game. When you play a lot of fast games against an opponent who has different strengths from yourself, you'll pick up new things by seeing what he does. He won't be doing anything that new to him, and you won't be doing anything that new to you, but it can be interesting to get to know his game.
Once you've played many games like this against one opponent, you're really not going to learn anything new unless you start to think for longer (in chess), or play something else for an RTS.
