Whilst discussing preflop stuff with a friend in poker, I mentioned that I only 4bet or fold, when a reg opens and another reg 3bets, and only cold call when a weaker player is involved. He pointed this to be a massive leak and we then had a rather long discussion about loads of specific spots preflop where I may be having trouble.

I don't want to get too much into that conversation here but I am interested in what the general consensus is regarding this area. The most troubling area in my own game was being in the BB facing a re-steal from the SB vs the button. SB 3bet being 18% linear or higher and button opening 50%~ and folding to steals 65%~.

I like to 4bet or fold in this spot, as cold calling I feel would be hard to balance, but after speaking with my friend I now think this may be a leak.

What are you guys doing in this spot? I play 100z and my friend plays 200z as higher on eurosites.
