Hold'em table

I hold 5s3s, a weak hand that is unlikely to win against the blinds' range. Folding preserves my stack for better opportunities.

Q2o is too weak to complete or raise out of position against the big blind.

J2o is far too weak to open from the button even in 3-handed play, making fold the clearly optimal choice.

Button folded, so it's SB vs BB heads-up. 75o is weak, but completing invites a raise and folding gives up the pot; a small raise with position disadvantage is marginal, but 7-5 offsuit has playability and BB folds often enough to make a 3x steal roughly breakeven-to-profitable in this blind-vs-blind spot.

With KdAd in position, I raise to 600 to isolate the small blind's preflop raise and build the pot with a strong hand.

7-5 offsuit facing a 3-bet out of position is a clear fold; the hand plays poorly and the pot odds don't justify continuing.

AKs on the button in a 3-handed game is a premium hand; open-raising to 2.5bb builds the pot in position and is standard.

Seat 3 raised to 250 with position and initiative. My 5c Jh is weak offsuit and unsuited to the raise size; folding preserves chips against a likely strong range.

Q4o is too weak to defend out of position against a button raise.

With 4h-3c on the button and two players already invested, I have no hand strength and no position advantage to justify a call or raise. Folding preserves my 100bb stack for better opportunities.

Q9s is a strong suited holding blind vs blind; raising to 300 to exert pressure and take the initiative against the big blind.

9-6 offsuit is a weak hand facing a 3x raise from the small blind; calling 200 out of position with a hand that plays poorly postflop is unprofitable, so folding is best.

On the button in 3-handed play, Ten-Nine suited is a premier opening hand with excellent playability and postflop equity. Opening to 2.5bb is standard.

76o in the small blind facing a 2.5x button open is a standard fold; it plays poorly out of position with a big blind still to act behind.

I have a pocket pair of twos. Calling 150 to see a flop is reasonable; I'll avoid raising with this weak hand and keep the pot small.

I have a pocket pair of deuces with a set on the flop, but the opponent has shown strength preflop. Checking allows me to control the pot size and potentially induce a bluff or see a free card.

Checking back with ten-high and backdoor equity to see a free turn card in position.

The board is paired with a 4 and a 5, and my hand is a small pocket pair (22). Checking keeps the pot small and avoids building a big bluff catcher against a likely strong hand.

I pick up a flush draw on the turn after the flop checked through. Betting as a semi-bluff puts pressure on BB's weak checking range while retaining plenty of equity when called.

I have a set of twos on a paired board with a possible straight draw. Calling 375 into a 925 pot is reasonable to keep the opponent's bluff frequency in check without overcommitting on a second pair.

Board is paired with a Ten on the river, giving me a weak pair of twos with a possible straight draw that missed. Both players checked the flop and turn, so I will check behind to realize equity without risking more chips on a marginal hand.

I rivered top pair of tens with a medium kicker on a paired, straight-connected board; checking back safely realizes solid showdown value without risking a check-raise.

AJo on the button in a 3-handed game is a clear value open; raising to 2.5bb takes initiative and builds a pot in position.

With 7-4 offsuit and a min-raise from the button, I have no equity edge and will fold to preserve my stack.

96o is too weak to defend out of position against a button raise, even getting decent pot odds.
