never understood why that works in lhe, surely you put the same amount of money in whether you raise turn/chk river as you do if you call turn/call river. Am I missing something?

you fold out 6 outters that will catch up on the river a significant % of the time that would be correct to call the turn raise.

ex. you open 99 otb, sb 3bets, u call. (7sbs)

flop is K 7 3 he bets, you call. (9sbs)

turn 4 he bets, you raise... villain is getting 7.5 to 1 to call the raise

you're ahead of his range enough to call down profitably anyway, esp. if villain is capable of double barreling lots of turns. its a good play if villain is weaktight b/c he may fold a better hand. also if hes double barreling AQ, AJ, AT, etc... he may incorrectly estimate his outs at 3 rather than 6 (only the aces being live) since he expect you to have a king. thus incorrectly folding a live 6 outter on the turn getting 7.5 to 1.
