my personal opinion is that, while engines have indeed produced gems from time to time, this is not one of them. I really found nothing special in black's treatment of the game.
For once I think I'll have to agree with Lyudmil here.

This game just looks like a standard game between two super engines.

At this level, a lot of the really brilliant ideas get pruned away when the super engine sees a razor edge defense and assumes the opponent will too.

To see really brilliant computer chess, I usually goto my own engine personalities I've created like...

Rodent Topalov!

Look at the following games, against engines which are 2700+ on CCRL, so not weak, but lose brilliantly against a very realistic Topalov style.

For me at least, that's computer chess! :)
Those games of Rodent you've posted are truly beautiful too.
The below game is won by SF8 as black against Houdini 5 this time. SF8 has material deficit but with piece mobility/activity.

Having a material deficit and still winning against a Top 5 engine in a long time control is not common. That's why I consider these games beautiful. Rare to find these types of games, because most of the time a single pawn deficit can already mean a lost game at this 3200+ level.
thanks Mike, for posting this.

I liked this game better.

still, quite probably, at the end of the book:

[d]r1bqk1nr/p4pbp/2pp2p1/2p1p3/2P5/1PNP2P1/PB2PP1P/R2QK1NR w KQkq - 0 9

white is already lost.

that is why I hate any book longer than 1 and a half moves.
Did you see that quiet 36...Ra7! move of black? It forces and completes the fencing/trapping of the Na4. after 36...Ra7! the N of white has nowhere to go and will be recaptured within a few more moves. Haven't seen that kind of depth and accuracy in any GM games.

Anyway, here's how Deep Shredder shows of its gambit skills against Chiron 4, the Italy's number 1 engine rated 3100+ in an Alekhines Defence. This is a Brilliant game by DS13 too.

Throwing 3 pawns for free in exchange for an attack on the uncastled king of black. Materially black is ahead, but DS13 proved that his position and initiative compensated for his lost material. Very nice attack.

Here it comes..... :lol:

Typically negative TC comment: "Nice game, but nothing special. Shredder would never have played that game if Chiron had a REAL opening book. Black is already lost after 1...Nf6, so the game result is obvious."

My comment: Yeah, I've liked this new dynamic element in Shredder's play and although it's not a real contender anymore, it still has a unique and strong "opinion" in positions.

Chiron's 16...g5 is interesting too, and the type of move you'd expect from a human player (instead of the more sober 16...Bxf3 17.Nxf3 Ng6 where white's space advantage is still imposing.

16...g5 looks active, but severely weakens the f6 square (the only real drawback) and this was exploited beautifully by Shredder. Nice game.

very nice game - a quiet move not played was 22.Kh2! delaying the exchange...

Throwing 3 pawns for free in exchange for an attack on the uncastled king of black. Materially black is ahead, but DS13 proved that his position and initiative compensated for his lost material. Very nice attack.
very nice game - a quiet move not played was 22.Kh2! delaying the exchange...

The idea of 22.Kh2 isn't to delay the exchange, but to:

1. Play Rg1 attacking the bishop which is short of squares, and force ...Bxh3, which kicks the bishop off the h1-a8 diagonal, thus allowing Ne4 without fear of exchange with ....Bxe4 (a knight on e4 is much superior to a bishop there).

2. Play Ne4 and continue attacking the kingside.

Just a note: black cannot play ...Qxe3 because fxe3 wins a piece, so Kh2 also uses this point to buy time for the Rg1 idea.

Generally speaking, the attacking side should not trade queens and this is why some engines might not play Qxb6.

Personally, I'd feel the same and play 22.c5 playing for kingside attack with a clamp on the pawn structure, safer king and more space, but the 22.Kh2 would be too artificial (or sophisticated) for me to play.

This is the most beautiful engine game I've ever seen.

The play is suboptimal, but just look at the position after 30... exd2. Unbelievable!! Well done, critter :wink:

Absolutely beautiful.

I must say that such beautiful pawn play is a regular feature of Critter's wins. Really a shame that such a brilliant engine is discontinued.

Did you see that quiet 36...Ra7! move of black? It forces and completes the fencing/trapping of the Na4. after 36...Ra7! the N of white has nowhere to go and will be recaptured within a few more moves. Haven't seen that kind of depth and accuracy in any GM games.

Anyway, here's how Deep Shredder shows of its gambit skills against Chiron 4, the Italy's number 1 engine rated 3100+ in an Alekhines Defence. This is a Brilliant game by DS13 too.
