The game thread is getting too large and I find it difficult to go through the pages to see the analysis. So I thought I create this thread for easier navigation and following up of the game analysis. Please post your analysis with or without computer engines. Here is a site and instructions for chess diagram posting. 1. Open another browser window. 2. Go to site http://www.chessvideos.tv/chess-diagram-generator.php3. Setup the board position, check which color to move and click "Generate Diagram" button. 4. On the next page it takes you, you will see "Just the Image" with a link like this. 5. Copy and paste that link including the "img" tags in your post. Here is the game.

One that I was curious about was 22. Rf2. Sam played it and Pirc praised it, but I was itching to play e4 at that time. I'm not sure what the point of Rf2 was, except maybe to try and provoke d5. Don't know why PA praised Sam for that move (22. Rf2). He must have had some reason for that. First the position before 22.Rf2.  Okay, here is what I thought during the game. Let me grab from the spoiler cookie. 22.Re1! (idea to defend c4 with Bf1 in case of Knight attack from Na5 where b3 support is not possible. using rook to defend c4 would waste resources.) 22...Ne5 (22...d5? 23.Bg5! Kg7 24.Bxf6 Kxf6 25.cxd5 +/-; 22...Na5 23.Bf1 followed by Rd2 and Red1) 23.b3 a5 24.a4 etc.
22.e4?! (no need to rush since d5-push is not there.) 22...Nd4 23.Be3 Ne6! (23...Nc6?? 24.Bg5 Kg7 25.f4! idea e5 +-) Knights are active and black is ok.
22.f4?? runs into 22...Ng4 and Bishop is in trouble and the looming threat of Ne3 fork. Not worth for the c6-Knight.
22.Bg5? since it loosen up the bind to ...Kg7 and ...h6Now 22.Rf2 does the job of 22.Re1 in making room for the bishop to defend c4, but in addition you have the option to quickly double the rooks! That is why I think Rf2 is even better among the available options. It is not very intuitive like 22.e4 and Sam has found it!! Now over to you guys Petro, Krish, others and you can poke holes in my analysis!

But here Petro didn't follow up like I expected him to. Petro goes 23.Rc2. But here is an interesting line for Black in case of 23.Bf1. Position after 22...Na5.  23.Bf1 Nb3!? 24.Rd3 Na5 25.Rd1 Nb3 kind of forces white to play Rc2 to make progress. Again it is difficult to drive the b3-knight with Rd3 because of Na5-b3 etc. So I think computer can better tell the difference between 23.Rc2 and 23.Bf1.

I also liked 22. Rf2 with the idea of 23. Bf1 and then Rfd2. Although, 23. Rc2 did not spoil anything, since Black is totally out of viable counterplay ideas. For this reason, the move e4 for White, while it might work out tactically, unnesesary gives Black a prayer of getting a Knight to d4.
The question is how did Black get to such a miserable state? I am partly in fault for my 17..Nb4. My idea was that 18. Qb7 could be answered by Nc6 with a promising pawn sac. 18..d6 (that happened in the game) was a fall-back option. Mostly though, I blame the opening, especially 11..g6 that weakened the dark squares around the King and lost the Bishop that was supposed to protect them in one fell swoop.

I played 22. Rf2 because that was the second way that I saw to save the c-pawn and Rc1 looked unpleasant. Rfe1 never occurred to me, oddly, but I did think that the doubling option was nice to have.
Krish: by 40. hxg6, do you mean 40. fxg6? What move would save a pawn there? I probably would have played it if I'd seen it.

The game thread is getting too large and I find it difficult to go through the pages to see the analysis. So I thought I create this thread for easier navigation and following up of the game analysis.
The problem with doing it this way is that all the spoiler analysis is in the other thread, so here's a link to that one: Tandem Game 1

Sorry guys, cockroach played havoc with my computer power supply unit. Seems like a live cockroach is a good conductor or good enough to short circuit it. Had to replace the unit.
Cool, Kalten is joining in the analysis!! Where is Russianbear??

After 12. Bxe4 de4 13. Nh6+ Kg7 14. Ng4, Black can defend with 14..Bg5, I think. At least you have to show what's the big idea there to call 12. Bxe4 brilliant. White got a clear plus with the move played 12. Nxe7+

Okay, accepted, 12.Bxe4 is not that brilliant like I thought it to be, I must have missed out your 14...Bg5 on this line, however it looks to be interesting though. I was a little excited about that move because giving up the fianchetto bishop went against conventional play. Still I think there are some things for black to work out. Like,
12.Bxe4 dxe4 13.Nh6+ Kg7 14.Ng4 Bg5 15.Nd5
And,
15...Bxd5 looks bad. 16.Bc3+ f6 only move. 17.Qxd5 Nc6 18.Qxg5 and wins piece!
15...Bxd2 16.Qxd2 and I think black is more or less forced to commit 16...f6 (because after 16...Bxd5 17.Qxd5 and e4 pawn is gone and the backward d-pawn should be good enough for white). Black weaknesses are h6 square, d-pawn and white can simply develop with Rad1 and probably has good compensation for pawn.
I agree there is no need to unnecessarily complicate your position if you don't see the advantage clearly. But once again, it would be interesting to see how the computers would think about these two alternatives!
