In Search Of Meeting Invitation Webapp

Thursday, December 29th, 2005

I’m looking for a web-app that a frisbee group can use for scheduling games. Games occur often (one or more times a week, depending on the group) and have the same audience. There should be a way for someone to announce a game time and location that will be emailed to all members, and a way for each member to sign-in or out and leave a comment (like “will be late” or “bringing a guest”). And, of course, members should be able to check the status and see the sign-in status. E-mail access would be a bonus. The app needs to be responsive since game conditions can change on short notice.

Evite comes pretty close, but seems too heavyweight with the ads and self-promotions. Yahoo Groups does better at the group part but not as well at the event part. Plus it seems to have a big lag in message forwarding. Eventful looks promising, though it is in beta only and will surely get loaded up with ads like the others eventually.

The status quo is a simple unix app requiring an X-windows remote login to use :(. I’ve taken a webapp that the chess group was using and rebranded it for ultimate. It works OK, but it lacks any notification features.

Fall Chess Round 4 Game 2

Thursday, December 1st, 2005

Black to moveAfter winning the first game, I was able to relax a little for the second game of the match. I played Black and quickly found myself getting bottled up in the diagrammed position. I decide to go in for the possibly-complicated trade with Nxe5. Post-game discussion revealed that White saw farther ahead than I did but not far enough. He expected to win material by having his pawn take at e5, f6 and e7 to threaten my queen while letting my bishop take at b5 and c1. With my queen threatened, I would have to give up the bishop, he thought. Luckily for me, I was able to use the newly opened file to exchange queens and rescue my bishop.

Black to moveAfter the smoke cleared, I had taken his rook and pawn at the cost of a knight. Not enough of an advantage for a clear win, but certainly an nice advantage, nonetheless. After some regrouping of pieces on both sides, White started to bring his king into the action to reach the next shown position. However, it turned out to be a blunder since the tactical reply Rd2+ won his bishop.


Black to moveNow I had a comfortable lead, and in the final diagram I found a move to improve my overall position while giving back a little material. After Rxc3 Rxc3, Bxe5 I was a piece up with three strong passed pawns, and Black soon resigned.

That gives me 4 wins, 4 losses and no draws for a solid third place out of five.

Fall Chess Round 4 Game 1

Wednesday, November 30th, 2005

White to moveMy opponent for the fourth round had beat me twice in last year’s G15 tournament, but the games were close enough that I had hope of getting 1 out of 2 points and making a respectable showing in the A bracket.

I was White in the first game opening up with a Queen’s Gambit Declined with some early pawn action on the queenside to reach the first shown position. It looked like I could take the pawn at a5 with my rook, but I soon realized he was setting a trap for me.

Black to moveIf I took the pawn, he would take my bishop reveaing an attack on the rook. I calmly castled instead, and he traded bishops anyway.

I then started to put pressure on the a pawn. He decided to let me have it instead of getting all bottled up trying to defend it. Black can add a second defender to the pawn with Qd8, but I’m not sure he can add a third before I can add my queen as a third attacker. The pawn didn’t seem that valuable anyway since my extra pawn was doubled.

Black to moveAfter taking the pawn, we had a rook stand-off, and I took the opportunity to trade them all away since I often run into time trouble. After symmetrical knight invasions and threats, we reached the next position. Black could have traded knights while winning a pawn and leaving both sides with fractured pawn formations, but he had his sights on my king, thinking he might get a killer knight fork on f2.

White to moveHowever, the attack did not pan out, and after getting my knight back on the kingside to counter any further threats, I offered to trade queens before seeing a better use for my queen. Black refused to trade, and I had to offer again to get my queen back into position for the attack (this time I didn’t want him to take the trade). After he declined the trade again, we arrived at the next shown position. Now it was time for the attack.

White to moveWith his forces away, I was able to invade his king’s position starting with Qg6+. Taking two pawns gave me a strong position in the final diagram, but how to finish? With less than two minutes remaining on my clock, I was fortunate to see a combination to trade queens and win a pawn and knight to boot. After Qxc7+ Kxd7, Nxd5+ produced the fork to win back his queen. From there it was simple to promote pawns and win.

Fall Chess Round 3

Saturday, November 19th, 2005

White to moveI lost both of my round 3 games against another top player. In the first game, as White, I made the mistake of going after a pawn while leaving myself open for an invasion by Black’s queen. In the first diagrammed position I have the e4 pawn attacked twice while it’s defended once, but making the capture leaves my king exposed for an attack. I should have made a developing move instead, such as getting my bishop out to allow castling. (”First to castle, never hassled” was what the great Polinski used to chant.)

White to move The second position shows the quick penalty for my mistake. Not only is he going to get the pawn back, but I will lose more material, too. Luckily, Black didn’t find the very best moves, and I was able to parry the attack being down only a knight for a pawn. But further mistakes by me allowed him to quickly convert the advantage into a win.


White to moveI played Black in the second game, and my position looked pretty crummy coming out of the opening with two sets of doubled pawns, but I did have some hope for improvement. The extra f pawn could be used for attacking, I might coerce an exchange at c6 to undouble that pawn, and the rook might be able to attack on the half-open h file. The first two of those ideas came to pass, and I ended up with a favorable position after a few exchanges, as seen in the second diagram of this game, plus I had the “advantage” of two bishops vs. two knights.

Black to move Unfortunately, this is where I blundered, not noticing that the e7 pawn was attacked twice. Once he broke up the pawn chain, I couldn’t keep the remaining pawns all defended and soon lost.

Fall Chess Round 2

Monday, November 7th, 2005

White to move Round 2 brought my first (and probably only) wins in the tournament. We played these games on Yahoo, which worked out well. (Not only does is keep time and record the game, but it also prevents me from making an illegal move, like moving into check.) I was White in the first game. Computer analysis questions almost every move on both sides, but I managed to go up a couple of pawns only to soon gave them back trying to simplify into an ending with strong central pawns. I didn’t go about it the best way, but the position shown is still winning with a nice passed pawn. Unfortunately, I goofed with e4, giving Black a chance to equalize with Ra3+, but he missed it, too, and I survived.

Black to Move In the second game, I got off to an comfortable lead by winning a pawn and the exchange (my bishop for his rook), but I panicked a little in the given position. I suddenly saw the mate threat with bishop at h6 and queen at g7. The only way out I could see was to give back the exchange by Re6 (my rook for his knight). Turns out I had time to take the knight with the pawn and still meet Bh6 with Bf8. For some reason, he didn’t take the rook, though I still would have been up three pawns. I was eventually able to simplify the position and use my material advantage to win.

In the Round 1 notes, I mentioned I was working on using a JavaScript game viewer. LT-PGN-VIEWER looked promising, but I decided it wasn’t as good as the older Java applet. So the round 1 games are now available with the Java applet viewer: Game 1, Game 2.

Fall Chess Round 1

Monday, October 31st, 2005

Black to MoveFor the Fall chess tournament, we play two 15 minute games per match instead of one 30 minute game. I got bumped up to the A group this time and started out against the club’s strongest player. [I'm trying to set-up a JavaScript PGN player, but I don't have that ready yet.] The first position is from late in the first game with me playing black. It’s black to move, what do you do? Most moves, including the one I picked lead to quick death, but there is one move that keeps the game going.

Black to MoveI played white in the second game and started out a little unusual by getting my queen out early and breaking up his fianchettoed bishop. I didn’t know if it was sound, but thought it best to do something strange since I don’t know openings that well and may fall into a trap. Computer analysis doesn’t show any problem with the position. Black was worried about a kingside attack and quickly arranged to trade queens. After more trading and a lost pawn, I ran out of time in a poor position with a knight and rook and a few scattered pawns.

Two Week-Ends of Bridge

Raleigh Jaycee Center Ready for Bridge


Last week-end I played in the Raleigh sectional at the Jaycee Center (pictured) with a pick-up partner, Louise Watson, and this week-end I played in a Durham tournament for non-life masters with my mom. Louise has only been playing bridge for a year or so. We met her in Wilmington, and she and my mother kept in touch. Louise and I got along fine as partners, but we didn’t do well enough to place in the two sessions we played.

The Durham tournament was well attended, almost doubling the attendance from the previous year. Hard to tell that bridge is dying out.

Mom and I played in four sessions, getting an overall first place in one session and a placing in two others. The competition, at least at this level, is pretty friendly, and many opponents joked about being scared of us as they remembered our four first place finishes in the July Durham sectional. Usually, I’d remind them that we had come in last place on the final day of that event.
