Before Waterbury the builds of Pitch Long that splashed red were only run by a few people, primarily members of ICBM. Now it is commonly accepted as the best build because it allows for maindeck Wheel of Fortune and also leaves more room in the board instead of taking up room running Badlands. The maindeck that I am using right now is the exact same as
Peter Intile's Day 1 List. His sideboard had some odd card choices so the one I am going to post is my current sideboard configuration. For reference here is the list.

Now I'm going to discuss how and why I sideboard for different matchups.
Mirror-1 Necropotence
-1 Infernal Contract
-1 Rebuild
-1 Chain of Vapor
+4 Duress
Unlike most generic Pitch Long sideboards I am currently running 4 Duress because they are amazing against any form of combo and they are needed for my Gifts sideboarding strategy. The obvious cards to take are those that make you lose a large amount of life and then die from a mini-tendrils. I've heard of people leaving in Necro on the play because it is reasonable on turn 1 when your on the play but any time after that it's to much of a liability to cast. Personally I'd rather not have a card that's dead unless it's in the opening seven.
Drain Gifts-1 Swamp
-1 Rebuild
-2 Misdirection
-4 Force of Will
+1 Bayou
+3 Xantid Swarm
+4 Duress
This sideboarding strategy is quite different from what I did in the past. My old sideboarding was to take out a mixture of Accelerators, Threats, and Misdirections while bringing in 3 Xantid and 2 Duress. Sideboarding this way is so tough because you need to leave in enough blue spells to support Force but if you bring in to much disruption then you won't be able to throw enough threats at Gifts and they will just win before you do. The idea to board out Force of Will came from one of
TK's tournament reports where he took out Forces against Control Slaver. I don't think it is a good idea against CS because your primary plan is so strong but against Gifts this works well.
When you are playing with the post-board setup the deck is much closer to Grim Long than Pitch Long so you will need to change your style of play accordingly. Another benefit of this strategy is that if your opponent doesn't know how you sideboard then they may hold on to Ancestral for fear of Misdirection which will give you more time. Even with this sideboarding the match is still very difficult, if you find yourself in a metagame full of Drain Gifts then it would be a good idea to switch to combo with MD Duress. If it is a large tournament like TML Open or SCG then Pitch Long is still a fine choice.
Control Slaver + other Drain decks - updated
-1 Swamp
-1 Time Walk
-1 Mystical Tutor
-1 Mox Pearl/Emerald
+1 Bayou
+3 Xantid Swarm
When playing against decks like CS or T1T you don't need to make the same drastic sideboarding because they don't have the capabilities to kill you quite as quickly as Gifts. I board out Time Walk because I want to have as many threats against Drain decks as possible and it doesn't fit this role. If you see some random hate like Arcane Lab then you will need to board out a least 1 threat card in order to squeeze Chain back in the deck.
Fish-1 Underground Sea
-1 Mind's Desire
-1 Infernal Contract
-1 Wheel of Fortune
-2 Misdirection
+1 Swamp
+2 Thrashing Wumpus
+3 Empty the Warrens
The pre-board match against Fish varies quite a bit based on what list they are running. Builds that are similar to
Dave Feinstein's list are easier for combo because the only MD hate is Meddling Mage and 2 Stifles. Other builds have cards like True Believer and Orim's Chant to make life more difficult. The match gets drastically better after sideboarding against any version because you get to attack them from so many different angles.
1)Quick Empty the Warrens for 8-10 guys
2)Drop the Wumpspot and destroy their team
3)Combo off with Tendrils as usual
Now the Fish player needs to decide when sideboarding how am I going to leave in enough cards to deal with plans 1-2 while still not losing to Pitch Long's primary plan. Fish does not want to leave cards like Swords to Plowshares and Echoing Truth in against combo but they are either forced to make their deck weaker against Pitches default combo or have no answer to plans 1-2. The extra Swamp that comes in is good defense against Wasteland which helps when you are trying to activate Thrashing Wumpus twice.
Stax - updated
-1 Mox Emerald/Pearl
-1 Mind's Desire
-1 Infernal Contract
-1 Time Walk
-2 Misdirection
+1 Swamp
+2 Thrashing Wumpus
+3 Empty the Warrens
Now that EtW is out of the bag it's not quite as insane against Stax as it was originally because all competent Stax players will have an answer for it in the board. I still think it is stronger than other options because the Stax player is forced to side in cards that deal with EtW. Then in the match they are spending time answering goblins rather than disrupting Pitch's primary plan. In addition if they don't know that you have Empty in the sideboard then they may not bring in an answer and have no way to deal with 6 guys on turn 1. Another note about this sideboard is how useless Jester's Cap is now because the deck has 7 threats so they need to Cap you 3 times in order to get rid of all of your win conditions.
The reason I feel it's necessary to talk about these sideboarding strategies is not due to the cards that are coming in but rather what cards to take out. With a combo deck when you are siding out a large number of cards you want to make sure that you don't hurt the core of the deck. I would like to hear your opinion about other options for cards that can come out in the matches when you are sideboarding heavily.
Another idea that Eric Becker suggested is sideboarding Scrubland and Orim's Chant in place of the Bayou/Xantid Swarm. This seems like a very strong idea because most builds of Gift's are running 2-3 Repeal which buys them enough time to answer Swarm and combo out themselves. Adding Chant to the sideboard would make siding against combo difficult because you would need to take out 3 more cards in order to make room for Chants. I feel the strongest place for Chant is in 2.5 and 5c Grim Long because unlike other combo builds all they have for disruption is Duress so the combination of Duress and Chant would make there combo match stronger.
