Hello> The program says its playable, answering f3 with d5. The first 6 moves WhiteWhite maintains a score of about -69 (two thirds pawn) , keeping it on the 12th move.

Black atttacks white's king after 15th move after sacrificing a bishop! Now White is scores down (-1.3) in spite of being up a bishop! This happened with

engines Fritz 5.35 Fritz 6 and Crafty

I then activated the Fritz8 engine, keepin in the Fritz 6 and setting back to three moves deep.   On the 38th move, Black lets go of a bishop to a knight fork check in order to keep four pawns over two pawns. In one sequence the game ends with White working a rook pawn on the H file, then with a knight remaining for a draw.

In the other sequence, after move 38, White gives up knight for Black's last pawn on c3 after I entered the game to play for White, moving Rook to h8. Thereafter White wins the dodge, queening the pawn on move 91.

It goes without saying, the computer looks at all pathways equally, not the way

a human sees the game as a position that has pathways.  The situation is Digital with the Computer: it either is 'go' or "no go" . "go or no go" not necessarily to

the end position but to the increase or decrease in score. The computer does not look at holes, only at sequences.

Therefore, even though there are games in which the Computer wins at Hammersahlag for White,  that does not mean encouraging players to try it in

tournaments; especially where there is time pressure.

This is a legendary opening.  It's absolutely about the worst White can play - what the heck is he thinking? - but it was played regularly in the '90s on the Internet Chess Club by a player who demolished nearly everyone with it.  The rumor was that the player was Bobby Fischer, although no one ever proved it.  The player was beating masters rather easily with it, which means he must have been a very strong GM, no matter who he was. 

It might just as easily have been someone like Ivanchuk or Shirov, though.  Just the sort of stunt those guys might pull, and they were strong enough to pull it off, even back then!

 

 


I thought that was later shown to have been a computer.

On the subject of the original post, it's a really bad opening for white, but there's no way to quickly and decisively crush it with black, so in a way it looks much worse than it is. Bottom line, it throws away white's advantage and gives black a significant advantage, I think probably enough to win over the long haul, but it's not so clear. And I got humiliated several consecutive times against the opening when playing against a FM friend of mine in the skittles room of a tournament a while back. They were all G/3 minutes, and I think the time pressure had more to do with me losing than almost anything else, including his superior playing strength. Also, I was completely unacclamated to such fast controls at the time, I suspect I'd pull some draws now.
