Hold'em table

53s is too weak to open profitably from the button even 3-handed.

Button folded, so it's SB vs BB heads-up; Q2o is a marginal but playable hand with position disadvantage, yet a small raise to steal the blind is standard and profitable against a single opponent.

With 4d6d on the button facing a raise to 300, the pot odds don't justify continuing preflop with such a weak hand, so I'm folding to preserve my stack.

J2 offsuit on the button in a 3-handed game is a marginal hand; folding avoids playing a weak, easily dominated hand out of position postflop against two opponents.

5d 7s is a weak hand with no immediate equity or playability, and I am out of position facing a raise from the big blind. Folding avoids putting chips in with a speculative hand that is unlikely to improve enough to justify a call or raise.

I have As Ks, a strong hand. I'll raise to 300 to build the pot and apply pressure.

Holding J5o out of position facing an open raise from the button is a clear fold.

Q4 offsuit is a weak, dominated hand out of position against a button open; folding avoids playing a bad hand OOP despite decent pot odds.

43o is far too weak to open even on the button in 3-handed play.

Button folded, I'm in the SB with Q9 suited heads-up vs the BB; this is a clear raise to take initiative and the dead blind rather than limping or folding.

6c9h is weak and unplayable out of position; facing a 300 raise with only 200 to call, folding preserves my stack.

T9 suited on the button in a 3-handed game is a clear open-raise; 2.5x sizing is standard.

I have a connected 7-6 suited-ish hand that plays well postflop, and calling 200 into a 400 pot keeps my implied odds alive without overcommitting preflop. Seat 2's raise is modest, so I'll see a flop and reassess.

Getting 4 to 1 direct pot odds closing the action with a pocket pair to set-mine.

I have a gutshot straight draw with 7c6d on a 4h7s4d board, giving me a backdoor flush draw as well. Checking is optimal to control pot size and see a free card while keeping bluff options open.

Holding an underpair in a 3-way pot out of position against the preflop raiser, checking is standard.

Paired, dry board checked to the preflop raiser; a small c-bet with overcards and backdoor equity folds out many better hands and takes the pot cheaply.

I have a gutshot straight draw to a 5 and a pair of 7s, so calling the small bet keeps me in the hand cheaply while I assess the board. Raising is risky without a strong made hand, and folding would waste my equity on a draw-heavy flop.

Holding an underpair to the board multiway facing a bet and a call offers poor equity and reverse implied odds, making folding the standard play.

The board is paired with a 4 and a 5, giving me a gutshot to a 3 or 8 for a straight, but I have no made hand. Seat 2 bet the flop and I called; checking now keeps the pot controlled and lets me see the river cheaply while preserving bluff equity if seat 2 is weak.

Semi-bluff with the nut-ish flush draw in position after the opponent checked twice; betting adds fold equity against weak pairs and draws while we still have 9 outs if called.

I have a gutshot straight draw to the 8 and a pair of 4s on the board, giving me decent equity. Calling keeps me in the hand without overcommitting on a scary board where seat_2 is showing aggression.

Board is paired with a Ten, and my 7-6 is likely behind seat_2's aggressive line. Checking to control pot size and avoid bloating the river with a marginal hand.

Rivered top pair with T9 on 4-7-4-5-T; opponent has been passively calling and checked the river, so a ~36% pot value bet targets worse pairs like 7x, 88, 99, and 66, while folding to a check-raise.

I have a 7-high straight on the board and calling 1000 chips is profitable against a small river bet. Folding would be a mistake given the strong made hand.

I have Jh-As on the button with no callers yet. The blinds are small relative to my stack, and I don't want to play a weak suited hand out of position against two random ranges for only 150 in the pot.

74o is too weak to complete or raise from the small blind out of position against the big blind.
