Thank you.

Hmm. Very interesting games. 15.Qh4 (Tornow) may be the more clever move based on this. If 15...Rg8 like in the other game, greed with 16.Qxh7 should be pretty good. Don't see why black should be able to afford to lose a second pawn, especially after playing something slow like Rg8. The option I suppose is to make some pawn move on the kingside pretty much like in the game (probably g5 or f5 - the computer doesn't dislike f6 or h6 as well but they look slow and probably wrong). Early g5 seems to be weakening though (white goes Qg3 and threatens simply h3 knight move Qxg5) and against 15..f5 white has an idea of 16.exf5 Bxf5 17.h3 Ne5 18.Qa4. Having gained his queen effectively in play here, white will probably quite easily consolidate and start to torment black.

Maybe the game continuation for black in the 15.Qh4 game is best although it looked to me like white played impressively and had good positional understanding to see that after 18.Kd2! black had no good way to further an initiative. 

In the second game g5 was played only later to secure the e5-c4 path for the knight and only once white had gone queenside with the king. Then it may be to late for white to exploit the weakening very much.

I kinda like my move (13.Bc6) better compared to 13.Bxd7 after seeing these games. Both seem highly critical though and black really seems to be struggling in both cases. It's also a highly important variation for black to have work .

Have a nice day.

Ditto what fling said.

The user is going to have to be clever when creating the pdf. I checked one of the pdf samples from New in Chess, it was 299 kB for 27 pages so 11.1 kB per page. That's fine, assuming only one page is uploaded. But a chess book scanned by Google was 3.41 MB for 61 pages so 57.2 kB per page. That's a little wasteful. Some of the print-to-pdf programs tend more to the Google size instead of the New in Chess size. I remember my first chess pdf was not very clever, it was more than 1 MB per page, created from scanned TIFFs.

Hi.

I must have a crappy corr database then. But I will endeavour to have a nice day anyway. Anyone played my 12.Bc6? Did not expect to se many holds from black so this is intriguing.

Have a nice day.

I only allow PGN files to be posted here, but I suppose I could allow PDF too, I suppose there shouldn't be any risk?

Hey.

Apparently 
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 Bg7 5.Qd2 c6 6.Bh6 Bxh6 7.Qxh6 Qa5 8.Bd3 c5 9.d5 Nbd7 10.0-0-0 b5!? 11.Bxb5 Rb8 12.Bxd7+ got played directly in the only corr game to reach this position. I missed the game because I didn't have a corr database. White won very convincingly anyway. Compare to 12.Bc6 13...Kd8 from reply 71. Maybe black slightly benefits from having moved his king, strange as this sounds. This unpins the knight so black sort of threatens to get coordinated with Ne5+Ba6, white therefore probably should take on d7 but then having the king on d8 could be a slight improvement. Probably not huge though.

After 12.Bxd7+ Bxd7 13.Nge2! (basically the plan is just to develop and let black activate his pieces, content that the max he will achieve is to win back the pawn with a worse position). I don't especially like the look of the game continuation 13...Qb4 14.b3 Ng4 15.Qg7 Rf8 16.Rhf1 Nf6 (what has black achieved?) although maybe good advice is not so easy to give. Most appealing by looks seems to me 13...Bb5!? 14.Rhe1 Bxe2 (although this BxN exchange... what did I say about appeal?) 15.Rxe2 Qb4 16.Kd2 Qc4 when white looks at least somewhat inconvenienced but then again black could just be lost due to the minus pawn. The plan is something like Qc4-Qd4-Qe5 + pawn to g5 to control dark squares. It's also not hugely inspiring though.

Have a nice day.

AfaIc the mistake is fixed. Thanks, both GM TK and CbT.

My apologies, yes PDF> pgn
