Flat instead of 3bet a bit and see how a few hands play out, I've recently tried stopping 3betting almost entirely. On day one of the DTD £1k I only 3bet once, with Q3o, and it didn't get through. On the whole tho flatting seemed to work well and I won a lot of chips owning people in position postflop, I only blew up on Day 2.
I bring this into my game against players that never fold to 3bets, I like to flat them in position and float them alot. They eventually get tilted and want to check-raise/shove the turn with Gutshots, flush draws, air the usual and this is the times when I usually have it. The thing that fascinates me is everyone cbets now 100% even into like 3 callers with air without reading the flop texture correctly or without thinking about players calling ranges, this is an old move imo. I think checking back strong and weak hands in position is something you should definately bring into your game to balance your ranges. Also fwiw I think 3betting is still a profitable play just aslong as its against the right villain and you have position.
