I definatly don't think that enough people will even be able to fold a ten in a 15k tourney on partypoker to make this an even remotely viable push. Checking behind is definatly the best option, because even if you go for the smaller bet to represent a Q, most people will just call out of frustration. You really need to have a good read that this is a solid player that is able to make such a laydown to make any sort of bet here.
