I went to a W/end tournament in Cork (great place) which was very enjoyable despite fact I didn't quite play good enough.
I drew on Friday night with Black – played the dragon to his e4
I won all 3 games Saturday - 2 Grob's with White and another dragon.
On Sunday morning there was just 2 players with 4 from 4 so they played each other on board 1. There were 3 of us on 3.5. I played against 1 of them and won again with the dragon. The other player with 3.5 lost so the results on board 1,2 and 3 left one player with 5, one with 4.5 (me) and several with 4.
So for the last round I was playing on board 1 needing to win game to win tournament and the 400 euro. All he needed was a draw. Unfortunately for me he had also already played with Black 3 times so one of us would have to play with black pieces for 4th time. It was me.
Played KID against his d4 and was holding my own. He wasn’t risking much cos he only needed draw. Tried to push for a win, made small positional mistake with my Queen followed swiftly by missing a tactic and he won a piece. Because he was short of time I played on a while a piece down trying to swindle a draw with a perpetual check. He played out win well though and didn’t make any mistakes I could see so resigned when he exchanged off my Queen. Oh well, another one bites the dust!
I have no engine for analysis. Can anyone have a look at this and see where it all went wrong (before the obvious 30…Bxc6 blunder!)
I suspect that 27…f6 wasn’t the best plan. Perhaps cxd5 with central attack would have been better? I also think 28…Bxf6 was weak. If I’d recaptured with Queen I would have minded the e6 square. I don’t think his attack was all that strong before I gave him a piece! Who was ahead after his 27. Qh4 - I'd say it was fairly even
Help appreciated.

Thanks for advice though. I'll look at that when my home machine well again.
Fritz says - Yeah, 27...f6 wasn't the best move. It would allow white to play 28. Qh7+ Kf8 29. Qxg6 with white a pawn up. (Black can't play 28....Kf7, because then 29. Rh6 quickly gains more than a piece for White. Best play would continue 29...Kf7-e8 30.g5xf6 Bg7xf6 31.Qh7xg6+ Qe7-f7 32.Qg6xf6 Qf7xf6 33.Rh6xf6)
With an 8-ply quick check, Fritz liked 27 ...c5-c4 28.d5xc6 Rd8xd1 29.Qh4-h7+ Kg8-f8 30.Rh1xd1 Bb5xc6 31.b3xc4 Qe7xg5 32.Rd1-d6 Qg5xg3 33.Rd6xc6 [-1.19/8] (Although when I let the analysis run longer, Fritz came up with different lines.)
White's 28th move let you off the hook and would have given you a very slight edge had you played 28...Qe7xf6 29.Qh4xh6 Bg7xh6. With the played moves, after 29.Qh4-g4 Qe7-g7 Fritz gave White about a pawn evaluation edge, and White has a choice of a couple of lines. (And I think a third different line with slightly less than a pawn edge.) But both of the better lines generally use a sac of the knight via Ng3-f5 combined with soon playing Rh1-h7. (After the knight sac, the White queen captures the black pawn on f5 and protects the rook when it moves to h7)

Originally posted by RagnorakI just inputted the moves manually into Fritz, and guessed that the right move was 11.Ng1-e2, based on general development. Looking at the later moves, it turns out my guess was right. Also, I assumed 19.Nc3-e2 was the right move.

Originally posted by malingaYou're pretty close. Fritz's initial suggestion of 27...c5-c4 starts out at an eval of -1.25, but at 11 ply it drops to -0.25. After 11 ply, a handful of other lines give evals ranging from about -0.9 to -0.7. (And more than a dozen lines ranging from -0.9 to -0.1)
Who was ahead after his 27. Qh4 - I'd say it was fairly even
Originally posted by Mad RookYou are right with your assumptions. Thanks bvery much for your effort Mad Rook

Originally posted by Mad RookAgain thanks a bunch.
I just had Fritz look at your 27...c6xd5 idea. Eval was about -0.6 or so until Fritz hit 10 ply, then the eval changed to -0.3 (that's a minus 0.3). So that idea wasn't bad.
Idea here is to deflect action away from my Kingside and maybe open up diagonal for B on g7.
Of course moving my bishop to f8 was very bad. I see that now. Better here would have been Qd6.
Originally posted by malingaI can't comment on the strategy of Black's move 21, but Fritz actually evaluates 21...Bg7-f8 the same as 21...Qe7-d6. (-0.69 for both moves at 13 ply). It likes 21...Bd7-b5 the best at -0.97. So, at least tactically, the bishop to f8 isn't a real bad move.

Originally posted by Mad RookThat's interesting especially as effectively it's giving away 2 tempos after Qh2 forces it back.
