When playing Blokus, it’s important to have a sense of the value and importance of the pieces. Some pieces are better for attacking moves, others for defending, some are great for cut-moves, others usually just for kiss moves. If you are able to balance which pieces you use by considering which pieces you will need later as well as the single best piece in a given spot, you will be able to get the maximum value from each of your pieces, not just the ones you use earlier in the game. The following is the list of the 4 most important pieces, in order, according to Mike_Yosuke. All of these pieces are flexible, and can serve multiple purposes when using them, though they have different qualities which make them so important.
4. The N5. This piece has great reach, and the ability to quickly move around an opponent’s corners, often blocking their most advanced corner in the process. At it’s best it quickly circles around the front edge of an opponent’s piece, pushing them back and completely changes the control of of one area of the board. Its length also makes it a great piece for connecting (or the threat of connecting). The N5 can also make great blocks, and has the potential to set up a 1-hole and 2-hole in sequence to defend your space really well. And unlike the L5, the only other piece with the same reach and connection capabilities, the N5 doesn’t have many natural leaks, and can often be played in such a way that it doesn’t leave any leaks at all.
3. The F5. This piece is all about defence, it is the block-master. It contains all of the L4, Z4, and T4 shapes, making it at useful block in many situations, and it is often the perfect piece to set up the blocks (almost always at least 2 blocks in one piece) you need to keep the pressure on your opponent. Even when this piece is used in attacking, its strength comes from being able to prevent counter-attacks at the same time. Add to all this that it has tons of corners and no natural leaks, and it’s clear why this piece makes the top 4.
2. The W5. This piece is the master of flexibility. It has the stairs shape built into it, allowing you to set up un-passable positions quickly, or to create a series of 1-holes in the same move. It also protects you from being forked, and can often end an opponent’s attack in a single play. On the other hand, the W5 is great when attacking as well, being a piece with maximum length, that allows you a quick, strong attack while preventing counter-attacks with ease. Again, this piece has no natural leaks, and creates tons of corners for you. In fact, the strength of the W can easily be missed because it is often used early in the game, but it gets used so often on the first 3 turns precisely because of how strong it is, and when you still have it after that, you can almost always find a great use for it.
1. The Y5. Of the top 4 pieces, this one actually has the biggest natural leak, but in practise that leak is almost never exposed, and the Y is completely safe. Also, it can set up great blocks, has lots of corners and is very powerful in connecting because it can connect while defending itself at the same time. But it’s true power is it’s speed when circling. It can be used as a cut move which can’t be cut-back, or a kiss move which has nearly as much power as a cut because of the easily defend-able corners. At it’s best it can command an entire side of the board by itself. And it is often the best piece for forking an opponent. When you’re using your Y5, you almost always get a great move out of it, but be careful to make sure that you’re really getting maximum value, because you’ve only got one of these per colour!
The problem with the Z5:
Many people might have wanted to put the Z5 on the above list as well, seeing that it has full length, no natural leaks, and seems like it can often set up a series of 2-holes, which can be just as effective as a series of 1-holes. But the problem with the Z5 is that as soon as you use it, the piece you want most is another Z5. It sets up perfect i2 holes on both sides, but the best piece to close them off is already gone – itself! If you’ve played a lot of games, pictures like the ones below probably seem familiar to you, and you may have spent a lot of time thinking about how strong the Z5 can be, and worrying that you just don’t know how to handle it properly. Well, good news, the problem is the Z5, not you!
This Blue player probably wants another Z5 to go right where the Green one is…
and this Yellow player could sure go for another Z5 where the Red one is…

Bears34 was player A, and surprisingly chose W-i4, a connecting opening. Even more surprisingly, Guiduf chose to play as Yellow/Green leaving Bears34 to make the connection. The game had many twists, and a number of questionable moves, but the outcome was that Guiduf won by 19 and advanced. After the game there was a lot of discussion about which move in particular was the biggest error. At one point Bears played a Blue U that Guiduf responded to with a Yellow i5, killing most of the relevant corners on the Blue U. Most players, including Bears34 thought that this was the single biggest error of the game, and was ultimately responsible for the outcome, but I maintained that it was not as bad as it seemed, and that Bears could still play well enough to stay in the tournament, or possibly even win the game at that point, but that more damaging moves came shortly after. To be fair, seeing the Blue U get killed (Guiduffed!) the way it did is definitely tilting, and could certainly have led to compound errors, but strictly in terms of move quality, it was not a tournament-ending blunder.
To that end I have done some analysis using a pentobi file, showing how I think the tournament was still salvageable by Bears34 after the Blue U, and how he could have even won the game if not for a much more damaging error (the Red N). You can access the file here (link : http://dl.dropbox.com/u/27727822/FS2013/bears34-guiduf-freestyle2013.blksgf)
The conclusion I end up drawing is that the Blue U was probably a mistake, but really only about a 3-point mistake. Yellow gained a sizeable zone in the bottom right on account of the Blue U, but also lost tempo, as well as some space in the small DCCZ Red shared with Blue. On the other hand, the Red N two moves later was a big enough mistake to cost the game (and in this case, ultimately the tournament).
The Blokus Palooza 2012 finals took place between Mike_Yosuke and ccc33. Mike won both games, and the tournament. I have made comments about the games in two separate .blksgf files.
The first game of the finals is here (link: http://dl.dropbox.com/u/27727822/Palooza2012/CCCvsMike-game1.blksgf)

Freestyle Blokus is a variant where one player first chooses the starting pieces for blue and red, and then the other player decides who will play as blue/red, and who will play as yellow/green. This style of game eliminates (at least mostly) the advantage of going first, and so a “match” typically consists of only one game, instead of two games.
Each year there is a Freestyle championship held between January and March. In 2012 the finalists were infamouswhiteknight and guiduf. infamouswhiteknight chose the pieces for blue/red, and guiduf chose to play as yellow and green. The game was incredibly close, with guiduf winning by a single point, and it was widely considered to be an example of an exceptionally well played and tight game.
I have included a .blksgf of the game, with some comments, and a few variations to explore some other possible moves.

Currently the site has been taken down for reasons that most of you probably at least partially understand. Many community members have come together to try to act as a single unit, and work to get the website we love back to a usable condition as quickly as possible. As such, I have sent the following email to Mattel. I would ask that others refrain from contacting Mattel – overloading them with complaints will not help this problem – in fact it is part of what started the chain of events that led to the current state of the website. If you would like to support this, please leave a comment in support at the bottom. If you have specific messages you think Mattel needs to hear, either post it in the blokus.com forums, or let me know, and I will do my best to help make sure Mattel gets the word.
In this puzzle, the goal is to play the best blue move (just one) on the current turn to secure a huge zone for blue (and ultimately red as well) on the top. As well as playing the move, you should make sure you understand WHY the move is very good. Ultimately I will post the solution as well as a separate file with an explanation about why the move is effective, exploring a few lines of play .
