Hold'em table

A6o on the button in a 3-handed game is a standard open; raising to 2.5bb takes initiative against the blinds.

A7 offsuit has an ace blocker and enough strength to three-bet against a button open. Raising avoids a difficult multiway pot from the small blind.

JTs facing an open and a large SB 3-bet, with the button still to act behind, is too thin to cold-call profitably. It also performs poorly in multiway or 4-bet scenarios.

A6 offsuit facing a 3-bet to 9.5bb from the small blind, out of position postflop; weak ace is dominated by a typical SB 3-bet range and calling 700 more into 1300 offers poor playability, so fold.

K4 offsuit is a reasonable button open in a three-handed game. Raising to 250 puts pressure on the blinds while keeping the investment modest.

86o from the small blind facing a button open with the big blind still to act is a clear fold; playing it out of position is unprofitable.

3c2c suited is too weak to defend out of position against a button raise even at these pot odds; folding minimizes loss.

Pocket aces on the button: a standard 2.5bb open builds the pot and keeps the blinds' wider ranges in.

J8 offsuit from the small blind facing a button raise with the big blind still to act is a clear fold; it plays poorly out of position and doesn't have the equity to call or 3-bet profitably.

T4 offsuit plays poorly out of position against a button raise and is not worth defending for another 150 chips.

Q9 suited on the button in a 3-handed game is a clear open; raising to 2.5bb takes initiative and pressures the blinds.

K4 suited has a king blocker and enough playability to occasionally three-bet against a button open. Raising avoids a difficult out-of-position call with the big blind still to act.

A8s is too weak to cold-call a 3-bet with the original raiser still to act behind, and the reverse implied odds are poor. A 4-bet bluff isn't necessary here, so folding is the disciplined choice.

Q9s on the button facing a large 3-bet (950 vs 250) from the SB; it's a marginal suited hand that plays poorly out of a 3-bet pot and is dominated by typical 3-betting ranges. Folding is the standard play.

QJ suited is a strong button opening hand three-handed. Raising to 2.5 big blinds builds the pot while keeping the sizing efficient.

T3o from the small blind facing a button open with the big blind still to act is a clear fold; calling out of position with a weak, dominated hand loses money.

76 offsuit in the big blind facing a 2.5x button open with 150 to call into a 400 pot; getting ~2.7:1 and closing the action, a call is reasonable with a connected hand that plays okay postflop, while a 3-bet is too thin.

Flopped bottom two pair on a J-6-7 board; lead for value against the preflop raiser since the board is wet with straight draws and the raiser will c-bet-call with many Jx and overpairs. Betting ~75% pot builds the pot and charges draws.

Top pair with a queen kicker is strong enough to continue in position, but raising this sizable flop lead would unnecessarily build a big pot with a one-pair hand.

Two pair (7s and 6s) on a coordinated board; bet for value against Jx, overpairs, and draws while charging straight draws (any 8 or 4). Fold to heavy resistance only if board gets uglier.

Top pair with a queen kicker is strong enough to continue against this turn bet, but the connected board makes raising too risky.

Two pair (sevens and sixes) on a J-6-7-5-2 board is well ahead of the Jx and overpair hands that called flop and turn; betting ~60% pot for value targets those calls while keeping sizing manageable against the few straights/sets.

Top pair with a queen kicker is strong enough to call this river bet. I need to win about 28% of the time, and the blank river leaves room for weaker jacks and bluffs.

In 3-handed play, 54s on the button is a standard open, and a 2.5bb raise uses position and fold equity.

A2o in the SB vs a wide 3-handed button open plays poorly as a call; the ace blocker makes it a good 3-bet bluff candidate to take the pot preflop or play with initiative.

T3 suited is too weak to defend the big blind against a 9bb three-bet, especially with the original raiser still in the hand.

Getting 650 to win 1900 with position and 100bb deep, 54s has good implied odds and playability against a SB 3-bet range; calling in position is reasonable.

As the preflop 3-bettor on a low dry board, a small range c-bet with bottom pair plus ace overcard denies equity from overcard hands like KQ/JT and often takes it down; I'll fold to a raise.

Getting about 4:1 against a small c-bet, our pair of fives beats the unpaired broadway hands in the 3-bettor's range and has some backdoor equity. That makes calling better than folding or turning the hand into a bluff.

Bottom pair with ace kicker on a draw-heavy turn after villain called a 3-bet and flop c-bet; barreling has little fold equity and I'd be bloating the pot with a weak hand, so I check to control the pot and keep showdown value.

Our pair of fives has some showdown value but is weak against a 3-bettor's range, which holds many overpairs. Checking behind controls the pot and realizes equity against overcard hands that have given up.

Bottom pair with ace kicker has some showdown value against missed club draws that would fold to a bet anyway, while the pairs and straights in their range won't fold; checking realizes equity and avoids bloating the pot with a marginal hand.

Our pair of fives has showdown value against the 3-bettor's missed broadways, and betting would mostly get called only by better pairs. Checking back realizes that equity cheaply.
