Live 2/5NL Uncapped..

[duh]

This was about a week ago at cesars 2/5 NL uncapped..

about 11 AM... i have about ~850 behind

I raise utg+1 to 25 with AQo..

Mp calls, CO calls...

Flop Q-10-x

I lead for 50... Mp folds... CO makes it 125 to go...
CO, just sat 1 hand ago, and is an old guy with beady eyes and about 900 behind...

I think i should fold here.. but I call and re-evaluate turn....

So pot is ~300..

Turn total low brick....

I check, CO INSTA-INSTA shovees for ~800 more...

I puke, show, then fold...

I get berrated because he was obviously bluffing with his giant overbet, and his beady eyes surely make this possible...

Thoughts and better lines please?
