ok to minraise to isolate??

Don't want to reraise big here as Tina is pretty tight and i expect possible high pp here. Yet don't want four seeing flop and thought her raise was low enough to price them in after my call.

Is this play ok?

This play reeks. You will still likely get a 3 way pot plus you're OOP and would like to be HU. Make a real raise so you can make a real cbet here and have some FE if you miss.

Yet don't want four seeing flop and thought her raise was low enough to price them in after my call.

I really don't think this is going to happen. 3 at most...

Don't want to reraise big here as Tina is pretty tight and i expect possible high pp here.

So make a real reraise and fold to another raise. Or make a real reraise and play postflop poker. Either one is better.

if you are gonna raise then raise, dont fuck around

point taken cheers.

This play has no balance.

I want to put the tight player to a real decision here.

I can only see doing this against a donk who is way over-playing his hands.

Also think about this. You want people to make wrong decisions about you in poker. Min-reraising will give them better than 3-1 odds heads up. Folding 3-1 odds HU is almost criminal. You must raise bigger to cut down the odds.
