Hold'em table

Q8o on the button in 3-handed play is a standard open; a raise to 2.5bb steals the blinds with a reasonable hand.

AJ is strong enough in 3-handed play to 3-bet for value and pressure the button opener, while also charging the big blind to enter the pot.

T6 offsuit is too weak to defend against an early open and substantial 3-bet out of position in a three-way pot.

Q8o is too weak to call a 3-bet out of position... actually in position, but the SB 3-bet range crushes Q8o and the implied odds are poor at 550 into 1150. Folding is the standard play.

Qc6d offsuit is a weak small-blind hand versus the big blind, and completing has poor realization out of position.

Button Q6 offsuit is playable in a short-handed unopened pot, and a minimum open applies pressure while risking little.

76s from the SB facing a 2x button min-raise works well as a 3-bet bluff: it has good playability and fold equity against a wide button range, and it avoids flatting out of position with the BB still to act. Sizing to 900 isolates the button.

6-2 offsuit is a very weak hand and I'm facing a raise and re-raise, so calling is not profitable. Folding saves chips for better spots.

Q6 offsuit is too weak to continue against a substantial small-blind three-bet after our button open.

Three-handed on the button, suited hands like T2s are within a wide stealing range, so a small open pressures the blinds.

98o is too weak to continue out of position against a raise, and calling invites further pressure from the BB. Folding saves chips for better spots.

Pocket twos have sufficient implied odds and showdown value against a button opening range, especially at this shallow preflop price.

Bottom pair has modest showdown value but is too weak to build a pot on this coordinated board. I check and evaluate the button's continuation bet.

This K-J-8 board favors my button raising range, so a small one-third-pot c-bet works as a cheap bluff with backdoor straight equity. The bet can fold out BB's weak hands.

Bottom pair has insufficient equity against the button's continuation bet on this coordinated board, with few clean improvement outs.

T4o is a weak hand and calling offers poor pot odds. Raising risks too much without a strong hand, so folding is the safest option.

Q7 suited is strong enough to raise for value and initiative heads-up from the small blind after the button folds.

T2o is one of the weakest hands against a 3x small blind open. Calling 200 into 400 would put me in with poor equity and often dominated, so folding is fine.

Button open-raise with suited J5 to leverage position and steal the blinds at a favorable price.

T2o from the small blind facing a button open with the big blind still to act is a clear fold.
