This was a game I played with Rybka with 1 minute play. I know I made blunders in this game, and I added moves I think I should've played in the comments. This was the first time I beat it. Any input would be appreciated.

I have a few questions about this game --

Since when does Rybka play the Nimzowitsch defense?

You were quick enough, both mentally and physically with the mouse, to play 78 moves in presumably under 60 seconds?

What type of hardware were you using that made Rybka so inefficient and ineffective, even considering that computers don't fare too well in short time-settings?

Yes, I don't like to be too sceptical, but seeing as after 650+ games, your blitz rating is 1334, it seems pretty unlikely you'd beat Rybka in a 1 minute game, especially since, as matthiassmall pointed out, you'd have less than one second to play each of your 78 moves. 58...Re2?? is a pretty massive blunder for such a strong program, as well.

Then again, I could well be wrong, I don't know much about computer strengths.

Even completely ignoring the blunders of the "computer", I mostly just want to know who actually has reflexes that are fast enough to accurately drag the mouse across specific distances and correctly drop the piece on the intended square (which would also have to be calculated lightning-quick) in under a second? You'd have to be The Flash.

Or he was bitten by a radioactive chess-piece, probably one of those darn knights!

Good point, Olimar. But if that is true, then I'll still have to say there was some extent of human interference -- I'm pretty sure Rybka plays e5 50% and c5 50% of the time against 1. e4.

Indeed, this can be explained with the use of Adderall.

I'm looking at the opening book of Rybka 2.2 right now:

1. e5 then: e5 (50%), c5 (50%); but it played Nc6

2. d4 then: e5 (50%), d5 (50%); but it played Nf6

In looking at some of the later non-book moves, it is still coming up with something totally different when given a split second.

I think it s enough of making fun of "Learnchess".All of you made your points clearly and reasonable ones.But enough of bad character jokes.

I'm not questioning his character, I just wish he would have more clearly explained the circumstances of his game.

Just some points....

1. You can run Rybka or any engine for that matter with a different opening book.  They even have specific books for UCOs and Gambits.  You can get these even on the Rybka site for free.

2. Depending on which program you use you can set them to 'pre-move' and easily make 78 moves.  I've had 0.9 seconds on my clock, on this site, in the live room and made over 15 moves.  Go to the live room and try it.. but first turn on Pre-Move in your settings on the Live Game page.

3. In these programs you can set the level of the program to 'Very easy'.  This may be the case.  The program limits its choices and only looks two to three moves deep.  Positional strategies and long eval'd combos are ideal.

3. Rybka 2.2 has an ELO of 2800.  Even with an opening of Nf6 it would crush most low rated GMs(heh... Low rated GMs).  And obsiously transpose into a standard 1...e5 opening.  In this game it transposed into a line of the Alekhine after move 3.

4. A computer would not play 7...f6.  Like any other higher rated player this is extrememly weakening and doesn't gain anything but scare the bishop away.  The center is always the 1st priority.

5. Yes.. I know I put down two 3's.

"maybe the player had infinte time and the computer had one minute?"

^^^ This is correct. In the end it was a little over 30 minutes for me. The only thing I messed with was the time clock for the program. I didn't know why it kept making that opening, I just played, and thanks LonelyNoose for that.
