I pulled this off Fransisco charts. Also snowie preflop advisor. What is the modern 4 bet range in this spot? Assuming 100bb stacks, btn opens 2.5bb and sb 3bets to 12bb, which hands are you 4 betting and to which size? I assume its a polar strategy with Ax and Kx blockers. The ranges snowie and Fransisco show, seem a bit tight. Why not 3 bet more K7s, KTo, Axs, maybe some 65s?
Any advice would be appreciated! Thank you in advance!
