It's in the DB alright if you know where to look -- try the Caro-Kann Defence.

Black should play either 4... c5 or 4... Bd6 rather than exchange bishops. His central pawn is on a light square; White's is on a dark square.

Agreed, this exchanged white's potentially "bad" bishop.

White had early on transposed the game into a Caro Kann with colours reversed. Black could have played a Panov-Botvinnik Attack (or maybe it ought to be called the Botvinnik-Panov, since colours are reversed?) by 4...c4.

More like a QGD exchange variation. White has the choice of a kingside attack or a queenside (minority) attack.

I probably would have tried getting the bishop out via g4

Although playing flexibly is generally recommended, it's clear that black probably should have committed king side by now. If b6 - Bb7 was always the intended plan of getting the light-squared bishop active, the pawn formation that is currently present is too easily broken up, as demonstrated through the game.

Good comment. I would have been reluctant to have weakened the c6-pawn, given that it is already under fire from the Q at c2. But White might also be interested in launching a minority attack at some point, at the very least to restrain Black's Q-side pawns to keep c6 weak.

This analysis would be completely winning for black after 23...Nxg8! A more likely line might be 16. 0-0-0 instead of the dodgy Bg6 which seems to just loose the exchange with more imminent material loss.

0-0-0 has long term consequences since White also has good prospects on that side. Not every pawnstorm is just after the king. In this case, the threats are positional as well. After gaining control on the kingside, White can attack the king forcefully. Black's bad bishop is reduced in value already.

Gung Ho. I think if you were going to play a6 you may as well have played a5. After facing a4, g4 and h4 i think i would be worried about b4 and g5! Kb8 is always an important move after 0-0-0. C5 is also sufficiently supported, but in this situation it would be hard not to underestimate whites queenside attack.

Not surprising from a high rated player. Notice how well protected White's king is. White can attack on both wings, Black can't maneuver quickly enough.

Black doesn't have the pawn breaks needed to put white's lack of castling into question; white makes a good positional judgment that his attack comes faster than black can generate counterplay.

I like 16. Kb8 sidestepping the c-file pressure. Your previous move 15. b5 seemed to severely weaken c5, which white has a firm grip of.

Qb6 is binding the Queen to the d pawn.. and with a line up of a queen and rook on the same file as your king. it is usually wise to move the king a-side or use a minor mobile piece for extra cover on the key d pawn. But Nb8 was a wrong suggestion i meant Ne8 this to re-deploy later after moves like 16.Ne8 17.axb5 axb5 18.Kf1 Nd6 as i think about it i would have made that move myself..

...Qb6? ties up the Queen, and after the exchange the pin forces Black to take with the a pawn and thus have a backward pawn on the open file, leaving the bishop severely restricted. If there is any hope of saving the game, the Ns need to be engaged.

Maybe heading for g2 to the safety of the kingside?

I was planning to exchange rooks on the a file so i expected a rook coming down to a1+ With my king on f1 i could easy move to g2 and cover it whit out giving up my central knight if exchanged

Black's game is very passive - there just doesn't seem to be anything useful that can be done. White can manoeuvre around at his leisure...

The manner in which White switches attention from one side of the board to the other is a remarkable feature of this game. As cliang remarked earlier, Black is ill-placed to do much about it.

This knight was watching the two sensitive squares of c5 and e5 around the king! However in the circumstances i dont think that there is much else that could help blacks king safety!

What did he say you should play instead? Clearly not 27... f6?? 28. Ne6+ so Black must lose the f7 pawn. Perhaps 27... Kc8 to free the Q, which currently has no useful moves?

27... c5 is in my opinion the best move not that the game can be saved for black but it prevents the next move 28.Nc5 and keeps several escape routes open. and i would have played 28.Nh7 if c5 would have been played..

The game is beyond saving. But in practical terms where the opponent is weaker, more stubborn defense is possible if Nc5 is prevented.

No holding back here. Very precise moves from white.

After Ke8, white can win a rook with Qxf8+, Kxf8, h7
