I haven't been posting much recently, but I wanted to kick off the new correspondence championship cycle with some tactics from the last one.

It was fun to play--even more with the variance at the end to give me the final round. Thanks to everyone for playing--I learned a lot from these games. One thing that surprised me was the importance of the openings.

In order of difficulty:

I may never defeat a stronger opponent in correspondence chess:

wlrs-Sholar, round 1
Spoiler:
I think this whet his appetite for revenge in future games: I was .5-1.5 in the balance. ...Bb4 wins the exchange.


White to move.

Sholar-Ajezz, round 2
Spoiler:
Despite thinking that there should be something there, I missed 24.e6! winning the exchange, and the game was soon drawn.


Already highlighted here...but worth repeating. White castles and then...

Sholar-hamstergang, round 2
Spoiler:
Out of the opening, I thought my position was much better, and slowly realized how wrong that assessment was over time. Castling loses to ...Bg4! but White's position has already drifted to somewhat worse even before that.


Black to move--can this endgame be saved?

Precise play by wlrs as White, round 3
Spoiler:
I entered a long forcing line out of the opening, giving up a piece for some pawns. Probably the entire idea is just losing. Here I found ...Nc3!? which at least makes White find some moves. Black's problem is that White is going to be winning in all lines where he keeps pawns on both sides of the board...

wlrs joked that this time (compared with the round 1 game, earlier) he had the better opening preparation. White's play was pretty compelling; I bought the book. Despite the loss, this was one of my favorite games from the tournament.


What is the correct assessment of ...Bf6 here?

Noir_Desir-Sholar, round 3
Spoiler:
Incredibly, Noir_Desir lost only this game in his 22 in the tournament. The opening went badly for him (I followed a line from a book which he related he owned, but didn't check), but I got a little sloppy a couple of moves prior, thinking that 30...Bf6 would hold the material advantage here and so not thinking hard about the obvious 27.Rxe6. After, I realized that Bf6 would lead to a draw, as Black can't avoid the checks after moving the rook and I needed a win.

Actually, 30...Bf6 might even lose...White can hunt the king very effectively with bishop and queen. One too-long line showing how White separates the king from his defenders is 31.Qe3+ Kd6 32.Bxf6 Rc8 (for example) 33.Qe5+ Kd7 34.Qe7+ Kc6 35.Qe6+ Kc7 36.Be5+ Kd8 37.Qg8+ Kd7 38.Qf7+ Kc6 39.Qe6+

Ugh the rd 1 game was pretty painful. The round 3 game is from the Kaufman repertoire book (a very good book) up until 21.-Nxa8, after which I figured "ok this has to work if this is supposedly better for White" and went for the Nb7 raid. Nc3 was a very interesting idea, and I thought I was losing control around 32.Kh3. Things stayed surprisingly well together in the end though.

A quick note while I have a minute. In the round 2 game with me (hamstergang) the additional moves ...b5 axb6 ep ...Rab8 Na4 had been played.

Oops -- sorry about that.
