For some reason, probably because I have a splitting headache, but also because I haven't really studied how engines are programmed to function, therefore, I really don't picture what you are saying very well.

It seems to me by raw calculation, an engine will chose a response that is most likely a book reply to an opening. If it doesn't perhaps these replies could be considered as such. I see how they may chose lines that aren't as good as book openings, but something tells me that they could come up with positions that could possibly be comparable, in terms of effectiveness.

I've actually never really known an engine to calculate 1... c5 as its best first move so I think Houdini must have been using an opening book for this game. It generally considers e6 and e5 as better, but that's because wafflemaster is correct in that engines don't play their openings as well as humans can (but engines can get away with it). For instance a lot of engines will suggest 1. Nc3 (the Dunst opening), which I'm under the impression that some opening theorists think isn't fantastic. 

actually c5 is an engine move. there is no book

Really?? How long did you let it run for? I'm running Houdini now and it's listing c5 as third, with e5 first and e6 second. Interesting.

i actually dont rememberthe first time control, but I do remember it saying e5 right up to the move and then it popped out c5, which surprised me

HOUDINI PLAYS 9...CXD4

Just noticed ...this is one badly organised...

cxd4 obviously. Wait... what did we play on move 9? (edit: saw it, nbd2)

10. cxd4 is so obvious.

Please update the moves in the original post.

10.cxd4

cxd4

sorry guys, I'm really stretched right now. i will update the original post soon

Is this still going?

cxd4

Christiansolider007, start a new forum, same topic, its getting annoying to go through all the other posts. Its confusing!

it seems to have died down, not many people are voting anymore

cxd4

You haven't confirmed the unanimous cxd and Houdini's response, so we're all waiting for that to happen.

ok I will. I just felt like there as been a lot less voting lately.

Houdini's reply will be out shortly

That's just because the recent move was obvious, don't get disheartened, people will come along once the position gets more interesting.
