1. 3streets when checked to, flat when he bets probably bet/f anytime he checks to us.

2. Try and get to showdown when checked to, fold if he bets.

3. Bet bet, check probably cause he'll call w/ worst Qx, underpairs, flush draws, 4x. If board was rainbow, probably bet, check bet, or call a bet if he leads river when turn checks through. If he leads into us call and re-eval on the turn based on bet size on flop/turn.

4. 3streets when checked to, call if he leads himself, betting whenever he stops leading or shoving the river or raising some scary turns possibly unless his bluffing range is super wide(we have no idea on turn frequencies so it's tough to play "optimal" here but raising on scary turns(T,9,K) is probably going to be the best eV play v an unknown turn bet frequency.

5. Bet flop planning to 2barrel unless the board pairs probably. Try 3streets anytime you bink a spade/Q or A. if he leads into us probably raise and take a free card on the turn since we probably won't have much FE on the turn and will essentially be AI.

I typed this up pretty quickly so some of it could be a bit off and probably not quite as in depth as you had hoped.
