Under what scenarios would you take a marginal to bad hand like T7o from the small blind in a blind war type situation and reraise as a bluff or call to float or bluff?
from the sb against btn? Almost never unless they were just folding wayyyy too much to 3bet
or do you mean the bb against the sb? There you can play wider for 3bet vs guys who open too wide/fold too much to 3bet or call vs guys who cbet too much and c/f turn or miss a lot of value bets or have a low cbet frequency and subsequently high flop c/f stat.
