Best way to meet the Kramer variation is with the Kramer defence. There is a book and DVD out on this. Just look up Kramer vs. Kramer 

Ponamariov used this variation to great effect fairly recently and against pretty good opposition:

Fair enough, but against the Hebden/Gallagher system (where Black delays castling), surely White should allow ...b5 and play for a quick f4 and e5, rather than Pert's ridiculous Bf4?

If you think this is a problem, my advise and GM Gallagher's advise is don't worry about it.  It is not a problem.  First because the percentage is very small, second the structures between this and the Saemisch for Black are the same and the tools are the same and the maneuvers and/or aims are very similar or the same.  GM Gallagher does address the issue of White trying to switch back to the saemish very well in his book.

In case White plays 6.g3, the fact that Black has played ...a6 now is not an issue either.  Black plays ...a6 is all or almost all his set ups vs the fianchetto.  For example 6.g3 0-0 7.Bg2 Nbd7 and we are in home territory of most or all set ups vs the fianchetto lines in the KID.

Be careful with stats.

Against those who don't know what's exactly going on in this system and how it happens this system does well.  Now, the truth about what happens when Black knows how White is weak and how White is not too flexible, then ...  another story.

Delaying castling, starting operations on the queenside, and a timely hitting the center works well, really well.

First game in point is a nice display by someone who is a KID guru and has been biten by this system before and thus learned from experience, GM Hebden.

Here White is one of the experts in this line, who has scored some very impressive wins with this system.
Black uses the same system of delayed castling, action on Q-side, etc.

Finally, guru with the white system meets guru with the Black system... for the second time !  And for the second time he loses.  Black get's play on all sides of the board (eventually) and White never really got his Kingside action to be significant.
