Cant see enough information to suggest weather i would of shoved in his spot. Lots of things to consider. like the clock, blindsat next level, how likely the other players are to call, and how light they think u are gonna shove, and weather there are antes in the pot is also important.
If there was antes at the point when u shoved with kj, and you had less than 10bbs, then i think shoving is standard, with 10-15 bbs then i may actually standard 3x raise, because it could look uber strong given ure position and shortish stack behind.
well done on cash though, not abad score at all...
