Double Seat Open Amid Plenty of Confusion

The flop showed and Casey Kastle checked in the small blind, as did Milad Oghabian in the big blind. Edgars Strupka bet 2,100 in late position and Kastle check-shoved for 23,500. Oghabian pushed forward his chips and Strupka quickly tossed in a single chip for the call as far superior stack.

Casey Kastle:
Milad Oghabian:
Edgars Strupka:

The turn and river completed the board, but suddenly the floor was called. What had happened? On the flop, Oghabian had kept some T-500 chips behind and was technically not all in. However, his shove over the top of Kastle would have been for his entire stack. As a result, the floor ruled it as accepted action and all chips of Oghabian went to Strupka.
