As I said at the time, I think the key is what exactly are you beating bar AK?
Loads of hands. If the guy c-bets the flop holding spades he can easily push the spade turn. He can easily push with A-10 or A-K. The fact there's 10k in the pot and he's only got 10k left means he's gonna be sorely tempted to shove atc. If he c-bets with 10-10 he could shove because he knows checking means having to muck in about 2 secs. A player may be tight generally but the other option here of c-fold and play on with 10bbs tends to loosen people up. Anyway, we don't know he's tight even. He could be American and would table A-rag 100% of the time.
The standard of the tourney was poor and most players were playing tight and incredibly ABC. The guy would never shove without thinking he is winning after a flop bet had been called. He also wasnt the type of player to c-bet. The last bet was also 14k.
The fact that we dont know he's tight should lean more to a fold considering that we have a huge edge on the field and we can find far easier ways to get chips and that were well above average chips.
