i think i have been pretty active at the table so i decided to flat call w KQs, rather than 3bet.

villain is a pretty standard TAG. 20/14 over 2000 hands and isn't the most agressive. most interestingly he only Cbets 45% of the time. his turn checkraise didn't really make any sense at the time, so i called, thinking he might give up on the river if it was a bluff. then he shoves...

i fold w/o really thinking carefully enough about it, guessing he must have me beat somehow. thing is, i have no idea what he has, his line just makes no sense. he would bet the turn if he had a big hand right?

this should be a call right?
what is his range?
ratio of valuebet/bluff on the river shove?
