21 ( +1 | -1 ) As a very general observationcastling queenside and then sacrificing a piece for an attack on a defended black kingside, is not very high percentage stuff. Better to open lines with pawn advances and /or sacrifices first.
58 ( +1 | -1 ) The position was more or less equal until white started his attack with Ng5 and h4. While looking very promising, the attack was nonetheles incorrect. Black responded, as he should, with a counterblow in the center. And 13.Rxd4 is an outright blunder - exd4 still offers chances.
Black lost his guard there for a moment with 15...Nxd5 allowing white to return part of the material with the nice Bg8! - but that was too little and too late.
24.h5 is another blunder, allowing the shot Nd3+ (Kb1 prevents that), and with the strong passed pawn on f3 black had a certain win.
77 ( +1 | -1 ) Mostly I agree with what zdrak has said, but I'll point out that 4. Bf4, while not bad, isn't particularly challenging since the Bishop often turns out to be not well placed on f4. 4. a3, 4. g3, 4. Nc3, and 4. Bg5 are more testing. 9. 0-0-0?! is positionally completely out of place given the tension on the Queenside. Much better is 9. cxd5, when Black has to make the recapture 9... exd5 blocking the a8-h1 diagonal since recapturing the the Knight loses a pawn. After 9. cxd5 exd5 10. 0-0 White probably has a slight edge. The correct response to 9. 0-0-0 should be 9... cxd4 10. Nxd4 (necessary to stop ...Nc6) dxc4 11. Bxc4 Nbd7 followed by ...Rc8. Playing 9... Nbd7 allows White to once again play 10. cxd5, although now the King is stuck on the Queenside.
42 ( +1 | -1 ) where did *I* go wrong? :)i just lost a game to the same player as tulkos with the same opening. here it is: board #802398
my opponent made what seemed to me to be a very nice bishop sacrifice, and then won the game. at the end, i was staring at the board wondering how it happened. should i have taken the bishop at all? i have to look over the game again....
19 ( +1 | -1 ) steve giving up the open file you had control of by 21.Rf1 was your big error.if you had exchanged it you would have at least equality if not more but to retreat allowed to much control to fall to black!!!!
45 ( +1 | -1 ) yeah, i don't really know what i was thinking there. Rf1 is a strange move. i guess i didn't think the d-file meant very much at the time or something.
about the sacrifice... i just had a look at the game, and i think 24.e3 to block the queen check instead of 24.Kh1 would have saved me from the winning attack. is this right? i played Kh1 without thinking, really, with the idea that i was in no real trouble! oops...
39 ( +1 | -1 ) e3!?if i was black i would play rook d3 win the pawn with check and though you can threaten mate with queen f6 after rook d3 i would take the pawn qwith check then return the queen to c5.it can be said you are in the game but those pawns are going to give you lots of trouble and i think he has more than enough compensation to be playing for the win here... sorry my friend
2 ( +1 | -1 ) BAD MOVES!!!!Rxd4 and h5 bad moves
47 ( +1 | -1 ) IndeedIt looked like you were ready to do anything to get some attacking chances - first risky queenside castling, then unsound piece sacrifice...
After 9.0-0-0?! even without 10.Ng5?! and 11.h4? black has no kingside weaknesses and it will take lots of time before white can gather enough resources for serious attack, whereas your king looks less safe because of central tension, an opportunity black has to open the c-file etc.
10 ( +1 | -1 ) ah well.The attack nearly payed off. I missed that black could defend his bishop with c3!
16 ( +1 | -1 ) Then againWhy gamble by going to objectively more or less lost position when one has a chance for small advantage (according to Atrifix, who is a very strong player)? :-)
10 ( +1 | -1 ) sorry for being offtopicbut i have always read atrifix as 'artifix'! sorry, pal. lol. i thought peppe had made a typo.
