A hand at 2/5 Foxwoods

[evagaba]

I was at Foxwoods 2/5 game with about $275 in front. I was down 2 buy-ins and this was what remained of my 3rd and final buy-in. Previously, I had flopped 3 sets and lost all 3 hands. I was second best all night when his happened.

I was in the SB with AJos, no diamonds. Raised to $15, I am the only caller.

Flop comes AJ7 2 diamonds. I had flopped 2 pair. Regardless of the betting, the turn brings 3 diamonds on the board. Villian bets, I raise ALL IN (at this point about 1.75 psb), villain tanks FOREVER and then says, "Alright I call, Come On Diamond, Come on Diamond!!!" I think yes, flush drawing!! Neither of us show our cards at this point.

River is a total blank. Villian says immediately and loudly "I have a flush". Digusted, I throw my 2 pair into the muck and walk away from the table.

Afterwards, I wondered if he really had a flush or was just saying that to get the exact reaction I gave him. Why would he be rooting for the diamond if he already had a flush? I already know that I made the mistake of mucking my hand pre-mature and it will not happen again.

I wonder at Foxwoods is it against the rules to misrepresent your hand like that? Or was I played into throwing the best hand away. I will never know but what do you think?
