Come on, limp with hands of different suits disconnected like, 57o, A3o, K4o.
And hands of the same suit ranging from 9 to A can raise 3x the blind, for example KTs, AQs and J9s. This strategy I always use.
Blind war are the most difficult spots to play because they have wide ranges, that said, try to play more passively if you don't have knowledge in this situation, it's always good to look for content to study the spots, pre flop and post flop
When stealing blinds, it's important to be cautious and pay attention to the players behind you and their playing style. It's tough to take blinds from an aggressive player, as they are more likely to defend their blinds with a wide range of hands. Attempting to steal from them too often can result in negative outcomes and unnecessary losses.
Blind wars are all about pressure, position, and opponent tendencies. Since ranges are wide, aggression is often rewarded. The more you study and practice these situations, the better you'll become at exploiting weaker players.
