Here's what happened, as best as I can tell.

Preflop: blinds 100/200
Hero has KK

2 limpers ahead of Hero, Hero limps, SB makes an illegal raise to 300, BB calls, limpers call, Hero reraises to 900, SB folds, limpers call, BB calls.

Flop: K52, no suits provided, pot 4200
BB leads out for 500, limper 1 calls, limper 2 calls, Hero raises to 4500, BB folds, limper 1 calls, limper 2 calls

Flurn (magical new round of between between the Flop and Turn), pot 17200:
Limper 1 moves all in for 3000, Limper 2 raises to 8000, Hero pushes, limper 2 calls.

Turn: 8
River: 7

Limper 1 has set of 5's
Hero has set of K's
Limper 2 has straight, 5 to 9.

Post-hand: Hero decided to write a rambling post about this that confuses the MTT forum.
