How Bad is Bad?

[Vuron00]

I was over at a friends house Monday night working on his router.

He's playing in a Party $10 Sng.. early in the tourney and all players are still in with average stacks.

2 limpers, SB completes and he checks with rags from the BB.

Flop comes AJT rainbow. Everybody checks.
Turn is a Q. Everybody checks.
River is a K.

Board is AKQJT with no flush possible.

SB checks and I tell him to go all-in for the heck of it.

He pushes in his stack AND 2 OF THE REMAINING 3 FOLD!!!!
