I'm playing at a .10/.25 table on full tilt...

I'm dealt KK in late position...the table goes around with 4 people calling the BB and no raises...i raise to 1.50 which is 6xBB and i get 3 callers...

Flop is 7 10 5 with the 10 and 5 being hearts...the very first caller goes all in for 17.50...i know it might have been a bad call by me...but i was sure he was on a draw...either straight or flush...most probably flush...and so i called...(maybe i shouldn't have?)

he "turns over" A 7 of hearts...turn is an ace which already beats me..and the river is a heart for a flush to beat me more....

how much does everyone raise to get rid of ace rag?...although they were sooted like the fish love...maybe i should of raised to 3.00 (12xbb?)...i dunno...but i was doing ok in ring tables...i stayed away from them for a long time cuz the bad beats cost a lot to me...
