preflop Analysis
87s is a standard BB defend against a BTN 2.5BB open. It plays well postflop and has sufficient raw equity at this price; 3-betting would be unnecessarily ambitious.
Defend the suited connector, apply pressure with the powerful flop combo draw, then build the pot immediately once the straight arrives.

Checking is correct from the BB. As the preflop caller out of position, we protect the checking range and can react aggressively when BTN uses a small c-bet.
The check-raise is a strong semi-bluff: our draw has substantial equity when called, while the raise also pressures BTN's unpaired overcards and weaker holdings. The sizing creates a pot worth winning now without committing us to continue blindly on poor turns.
Betting is excellent after turning the effective nuts. The 14.6BB sizing builds a stack-off pot while retaining calls from hands that connected or continue with strong draws; after BTN raises, we should happily put the remaining stack in.
