  Fusilli: <epistle> Thank you! I'll try singing it to my girlfriend in Tagalog and see how it goes! :)
Jul-04-15  epistle: good luck. Sana you hit the high notes well.
Premium Chessgames Member
  Fusilli: I just submitted four games that I played at the XXV Open Internacional de Gros, in San Sebastian (

Mariano Sana (2132) vs GM Roberto Cifuentes Parada (2449), 0-1

Mariano Sana (2132) vs GM Alfonso Romero Holmes (2469), Draw

IM Diego Del Rey (2378) vs Mariano Sana (2132), 1-0

Inigo Galarza Cenzano (2024) vs Mariano Sana (2132), Draw

Interesting games, I think.

The ratings in parenthesis are FIDE.

Premium Chessgames Member
  OhioChessFan: The Holmes games is pretty strong against a GM. You had a few winning chances even.
Premium Chessgames Member
  Fusilli: Thanks, <OCF>. The GM was very nice analyzing afterward. I did miss 21.Nd2, where he'd been in trouble.

I'm pondering whether to swing by St Louis this weekend to play the Mid-America Open ( I probably won't... it's hard for me to get into competitive play mode in the middle of the semester.

Premium Chessgames Member
  Fusilli: Just finished the National Open in Vegas. (Summary on my forum.)

Here's a miraculous save:

Sungho Yim (2373) v Mariano Sana (2205). White to play:

60. Ke4. Error. Winning is:

60. a7 Nd5+ 61. Kd4 Nb6 62. Kc5 Na8 63. Nd6+ Ke6

And here 64.Nxc4 wins (in multiple ways). But no 64. Kc6 h4 65. Ne4 Ke7 66. Kb7 Kd7...

it looks like white can't make progress! (Which may be what my opponent saw?)

The game continued:

60... Nc8 61. Na5

61... c3! 62. bxc3 Ke6 63. Nc6 Kd6

64. a7 Nxa7 65.Nxa7 Kc5

66. Kf4 Kc4 67. Kg5 Kxc3 68. Kxh5 1/2-1/2

Premium Chessgames Member
  Fusilli: Correction to my previous post. Actually, 60.Ke4 is fine because 60.a7 doesn't win, but black has to play 61...Nc7!, not 61...Nb6. The line ends up like the drawn position in the diagram I posted.

White had a win earlier though. I'll comment on the game page once it's up. I plan to submit my games.

Premium Chessgames Member
  OhioChessFan: Everyone needs to understand this position in an endgame. Kxa8 results in the pertinent 2 ranks:

click for larger view

So long as the Black King is adjacent to c7, Black plays Kc7, and so long as Black has a move, White's King remains trapped. As in this game, an extra Knight is pretty much worthless if it can't capture the remainder of Black's pieces.

Premium Chessgames Member
  OhioChessFan: Whew, I just looked again at my last post. Very sloppy language, but the trapping of the White King while Black can shuffle Kc7/c8 is an important endgame tactic.
Premium Chessgames Member
  Fusilli: <OCF> Indeed on that useful concept. It is also important, in this game, that the knight is the least efficient piece to stop a passed pawn. A bishop still has long range shooting power, and so does the rook (which can normally just capture the passer), but a knight can be completely neutralized by a fast-running pawn, especially on the a or h files. So, as a general rule, if your opponent has a knight (and hopefully no other pieces but pawns), it is great to have a far away passer.
Premium Chessgames Member
  Fusilli: For a dramatic example of a knight stuck stopping a passed rook pawn, see

Timman vs G Garcia Gonzales, 1979

The draw cost Timman his chance to qualify for the candidate matches that year.

  Fusilli: I'm just back home in Nashville from the US Senior Open in Naperville, IL. I shared fifth place with +4 =1 -1. More info on my forum. Tomorrow I am off to Philadelphia to play in the World Open, my fifth time. Wish me luck!
Premium Chessgames Member
  Count Wedgemore: Good luck, <Fusilli>! And congratulations to you for the fine performance you had in the US Senior Open. I hope that, when you have the time, you can submit your games from that tournament to be uploaded to the <CG>-database.
Premium Chessgames Member
  moronovich: And soon Happy Birthday to boot !
Premium Chessgames Member
  Fusilli: <Count W, moronovich> Thank you!

I will submit some games, if they are decent enough. But last time I did that (Daniel was still around) they never got uploaded. I hope I have better luck this time!

I just checked the World Open entries. In the open section there are at the moment 185 players or so, and I am number 111 by rating, which means I'll be paired with a GM in round 1, probably a GM in the 2600. Rough start!?

Premium Chessgames Member
  moronovich: <which means I'll be paired with a GM in round 1, probably a GM in the 2600. Rough start!?>

Yup,rough start,but perhaps you can play more freely in this case !?

At least,that it is what I tried in simular situations.

Premium Chessgames Member
  Fusilli: New photo! Thanks <Annie K> for uploading it! I did like the previous one, but I am older now, and this one is at the board--more fitting.
Premium Chessgames Member
  keypusher: Very nice, Fusili! How do you like your position?
Premium Chessgames Member
  Count Wedgemore: LOL, <keypusher>. An interesting position! I think our friend should exploit Black's early castling, and go for an all-out kingside attack, h4, g4, perhaps 0-0-0 followed by Rg1, etc.

And look at that Black pawn already on h5, hmm..what about a bishop sacrifice instead; Bxh5 combined with doubling the rooks on the g- or h-file? This could lead to an early blow-out!! 1-0 :)

Premium Chessgames Member
  Fusilli: <keypusher> <CountW> Yup, white is better. This was the position in the photo (with white to move; I played 21.0-0):

click for larger view

White is better because of the pawn on e5 and control of the black squares. Black's LSB is better than White's, but his control of the light squares will be tenuous (the LSBs got traded some moves later).

Over the next 15 moves I increased my advantage. He flagged after 35.Qe5+:

Premium Chessgames Member
  keypusher: <Fusilli> Nice! I have to say, I thought the Count was way out of line suggesting queenside castling. It's always easier to be reckless with someone else's king. :-)
Premium Chessgames Member
  Fusilli: <keypusher> Don't be too hard on the Count, we are all blood thirsty :) But it is true that in practice, it was better for me to close up the kingside than to open it. In fact, he forced me to do it, by placing his Q on h4 (which forced g3, and then I played h4 to prevent his own h4). He didn't have serious attack, but if I neutralized that, what was left for him to do?
Premium Chessgames Member
  Fusilli: Oh, sorry, I overlooked the 0-0-0 reference. But I explained why the kingside ended up the way it did.
Premium Chessgames Member
  Count Wedgemore: Well played, <Fusilli>. Your strategy was clearly the right one, much sounder than my reckless suggestions!

<keypusher: It's always easier to be reckless with someone else's king. :-)>

LOL. Yeah, don't I know it :) My own playing style has always been rather cautious. But as a spectator I always want to see the players taking big risks! All the more fun and entertaining to watch.

Premium Chessgames Member
  Fusilli: I got 10 new games up, from 2017-19. Thanks <Annie K> for uploading them!
