Hi

Let's suppose we open about 45% as a default range on BU, and larger against tight players in the blinds.
What range should we open when blinds are 3betting a lot ? For example with 2 regs 3betting 15% each vs BU (for simplicity sake I like to think "blinds 3Bet 30% total") ? Vs 2 regs 3betting 20% vs BU (40% total) ? And what for 25% total, or 20% total ? etc
Off course, here suppose that we want to avoid getting into too much 4Betting war, which is why we prefer to open tighter and hope they'll lose by 3betting too much against our strong range. That might be a strategy better designed to multitabling for example.

Thank you.
