Explanation of Back-raise
The most common application of back-raising is in a preflop squeeze scenario. Imagine the following in a 100bb effective cash game.
BTN raises to 3bb.
BB squeezes to 12bb.
SB back-raises to 25bb.
One reason why squeezing is effective for the BB is because SB rarely has anything strong. SB would have usually 3bet himself if he held a premium. If BB will get out of line with squeeze attempts, it’s possible for SB to smooth-call a premium preflop with the intention of back-raising against a squeeze.
