Beat: Four Straight Undersets

[DirectSplit]

Playing 25NL, the last four sets I flopped were all undersets. I dont recall anything like this over my entire playing history. Mercifully, two were to opponents with half my stack and one was to a ratholer.

During this joyous interval, I also flopped top FH, got it in on the flop, and lost to runners; I also checked into a a set on the turn and (of course) was being slowrolled by an overset. LOL stackaments.

But what I'm interested in is the prob of flopping behind with four straight sets.

Prob wizzards?
