I've seen that some regs nowadays 4-bet a lot OTB vs the blinds, which is a good strategy specially vs the SB. How to adjust properly? In your opinion, which of the following options will be the most +EV adjustment, and why?
1) 3-bet tighter vs them
2) Add 5-bet bluffs to your 5-bet range
3) Slowplay the top of your 3-bet range and call vs the 4-bet to get value out of his bluffs postflop
4) Something else (describe it)
