  3. Re:No way. on Kiro, the Foosball Robot · · Score: 1

    As for baiting and defense, I'm sorry, but very few defenders can block an effective snake shot even 1/3 of the time.

    I've played several pro-masters including Terry Moore (first person to win a national event shooting the snake and the #2 ranked player in the world) and Billy Pappas (who not only shoots cutbacks but can walk the ball around the goal face like a euro).

    Probably 2 of the more effective snakes in the world (Terry's is one of the top 5 for sure), but neither of them scored better than 50% on me. Pappas shot around 30%, me and a rookie forward took him and another pro-master, Mike Yore (reigning Open Singles champion in the US) to game 5 in a best-of-5 at NC States despite being completely dominated on the 5-bar.

    When they're real hot and reading the defense well they'll score around 60-70% but that's not the norm--the trick is to make it a mental game and let your defense dictate to them which holes to shoot, but keep it random enough that they can't read it well.

    I'm not saying it's easy--I think I block the snake just about as well as anyone in this area (we have no local pro-masters), though I'm far from the best goalie around given holes in other parts of my game--but if you dedicate yourself to trying to learn how to block it then you can shift the odds pretty substantially.

    You're still not going to brick someone consistently but if you look at the teams that win the major tournaments they always have bad-ass goalies--that's why Todd Loffredo switched to goal after all. Moving the opponent from a 65% shooting percentage down to 45% can give your team the possessions it needs to turn a loss into a win.

    That said, I still got beat because...
    The best defense against a good snake shot, is a better five bar. ...Terry Moore has one of the best 5-bars in the world (offensive _and_ defensive) and Billy Pappas's was more than adequate to tool on us.

    if the table were built with sensors in each of the guys (to indicate state/current position/speed of current rotation) and a sensor in the ball (or positional sensors around the edges that could read the location of the ball), I believe that the software would win now, without any improvements.

    Judging from the video, no way. It'd need _much_ better reaction time (faster motion of the rods) and some concept of how to block brush and chip passes (and shots). I also doubt the current software would even try to block an aerial even with GPS in it.

    The players in the videos are using the same stupid "whack the ball" strategy as the computer and they're managing to score on it sometimes--put it up against a real player and there's no way it'd compete right now.

    That said, give it perfect knowledge of the ball's location and fast enough reaction and motion times and it'll block anything. But they'd have to be a hell of a lot faster than they are now to have any hope of blocking even a rookie-level tournament player's shot (let alone pass).

  5. Re:No way. on Kiro, the Foosball Robot · · Score: 1

    The standard defense for the snake is to simply keep the defenders in constant motion and hope the shot deflects back into your 5-bar.

    You must lose a lot if you use that defense against humans. It's probably the best bet against a machine that doesn't try to read the defense (shoots random holes) but a good goalie is going to use a lot of baits and stints against a human opponent.

    Watch Louis Cartwright (2001 Worlds finals tape is a good one to get) or Bobby Diaz sometime--their shuffle is decidely not random, it's designed to force the opposing forward into a particular hole.

    Make that 1/3 of the time (if he's shooting a random option each time, just park on 2 of the options; if not, just move randomly on the 3 holes). 5 options off the snake (short and long push and pull, plus straight) would get it to 60% which is about what a good human shooter shoots in tournament play.

    A few coyote-dog crosses have been produced by human action, just as some wolf-dog crosses have been. And I think it's probably uncontroversial to say that it may, very rarely, happen in the wild, but to the best of my knowledge it's rare enough it's never been solidly documented.

    With respect to coyote-dog crosses it's very rare in the wild but there are some populations with dog blood. New specimens are now pretty rare but from about 1950-1980 when coyotes were expanding into the eastern US they were much more common (absence of like mates breeds frustration I guess). Still not _common_, but certainly documented--but the eastern coyote is _not_ a dog hybrid as was once thought (it does contain some grey wolf ancestry).

    With respect to wolf-dog crosses I don't know of any wild populations but there are sporadic individuals found--at least one well-known study concluded that a remarkably high percentage of wolf attacks on humans come from wolf-dog hybrids.

    With respect to coyote-wolf crosses, interbreeding is pretty common.

    my best guess would be that your 'coyotes' in this case are just wild dogs, or possibly even coy-dogs, coyote-dog hybrids themselves

    There's a terminology confusion here also: more often than not, "coydog" means the abnormally large eastern coyote hybrid which was earlier thought to be a coyote-dog cross but is in fact a coyote-wolf cross.

    Coyotes in Maine and eastern Canada almost all have wolf blood in them, and the wolves around Lake Superior all have coyote blood. And ALL known red wolves have coyote blood (if you find one without, call a conservationist!).

    That would be great except that interfertility is not transitive. There are cases (in birds and mice) where population A and population B can interbreed (and produce fertile offspring) and population B and population C can do likewise, but population A and population C cannot.

    The "can and do interbreed" definition isn't precise. Are wolves and coyotes seperate species under this definition? They normally don't, but they sometimes do (or did, witness the red wolf). Horses and donkeys generally don't, but sometimes do without being forced (if they're in proximity).
