What is your play against a small 4bet oop SBvsBU? Say some guy opens otb for 2bb and after we 3bet to 9bb in the sb, he 4bets smallish to 18bb. I don't have further stats on him, the site where i play doesn't allow tracking software. I only know that this is his standard ip 4bet size. oop he would 4bet a fairly standard size. What are we doing with our range, the odds that we get should allow us to call almost all of our range but we are oop, so i don't really like that. Jamming with our premiums also sucks a bit because we don't get that much dead money if he was bluffing, but is he bluffing more with that size? How would you perceive his range? My 3bet range looks like this (with MP3 being his 4bet range).

Equity Win Tie
MP2 41.31% 39.22% 2.08% { 66+, A2s+, K9s+, Q9s+, J9s+, T9s, 98s, 87s, 76s, ATo+, KJo+ }
MP3 58.69% 56.61% 2.08% { JJ+, AQs+, A5s-A2s, 87s, AKo }

Is the range that i give him too tight?
