I'm pretty sure microgamer means 11k blocked into another attack. Like what I said earlier, 11k blocked into 66k is a common "trap" online. But because 11k is -5 on block, it can be interrupted offline, but its incredibly hard to do so online if you aren't watching.
A frame trap is a move that gives plus frames on block. An example of this is Nightmare's iaga, much is +1 on block. The +1 makes his 6k, i14, come out 1 frame faster so that it is i13.
That low is laggy in my opinion. I know a few Siggy players that say it isn't, but I believe it is. To stop it, just interrupt it or block low. The K and A from that stance are high, so you'll duck them, and you'll block the low. Also, the B is slow enough to react to. The best thing to do is just learn a bit of Sigfried and you shouldn't have a problem dealing with scrubby Sigs.
