Hold'em table

Button raise with suited-ish connector JTo in a 3-handed pot is a standard steal/value attempt against two wide blind ranges.

A7 offsuit has an ace blocker and decent equity against a wide button raise; with no rake, calling 200 from the small blind is preferable to folding or bloating the pot out of position.

Getting 4:1 odds (150 to win 750) with a suited connector in the big blind, with deep stacks and good implied odds. Calling is clearly profitable, even multiway.

Ace-high on a paired King board has showdown value but is vulnerable; checking first to act controls the pot and lets me evaluate opponents' actions before committing more.

With 86s on a dry K-K-3 board and the preflop raiser still to act behind, checking keeps the pot small; my hand has little equity. If I fold later, I give up little, while a free turn might bring backdoor equity.

Both opponents checked a paired board; a c-bet with my gutshot/overcards can take it down now and has good equity if called.

Ace kicker on the paired King board may be ahead of the button's wide betting range, and 450 to win 1200 offers enough pot odds to peel one street out of position.

86h with no pair and only a backdoor flush draw on a K-K-3 board is facing a bet and a call, so I don't have the equity to continue. A fold is clearly best.

With ace-high on a paired king board I have showdown value and the best kicker, but betting risks a raise from trips. Checking keeps the pot controlled and lets the flop bettor reveal more.

I have no pair and no draw, but villain has checked twice on a king-paired board, suggesting weakness; a second barrel can fold out marginal hands and I have no showdown value to protect.

Ace-high on a paired King board faces a second barrel for 900 into 2550; opponent's range includes trips, pairs, better Aces and draws that leave me below the required equity, with another bet likely on the river.

KTo is a strong hand three-handed on the button, so raising takes initiative and leverages position over the blinds.

T3 offsuit from the small blind facing a button open to 3bb, with the big blind still to act behind, is a clear fold. It plays poorly out of position.

Q6 offsuit out of position facing a raise is too weak to continue profitably.

JTo on the button in 3-handed play is a clear opening hand; a standard raise to 2.5bb puts pressure on the blinds.

2-8 offsuit is a weak hand facing a raise; folding from the small blind is standard.

QJo has good equity against a wide button 2.5x open, and calling 150 into 400 offers favorable pot odds from the big blind.

With QJ on T-9-5 I have an open-ended straight draw plus two overcards, but no made hand. Checking to the preflop raiser preserves pot control and lets me realize equity cheaply.

Top pair with a jack kicker on a wet board, in position against a big blind who checked to me. A bet of about two-thirds pot gets value from draws and weaker tens and protects my hand.

With QJ on T-9-5 I have an open-ended straight draw plus two overcards, giving enough equity and implied odds to call 350 into 900 rather than fold or semi-bluff raise into a large c-bet.

I have no showdown value but a huge combo draw with straight, flush, and overcard outs. Leading as a semi-bluff can win the 1250 pot immediately and still leaves strong equity when called.

Top pair with a decent kicker gets 2.6:1 on the call. The BB's donk bet could be two pair, a straight, or a draw such as diamonds or J8/Q8, so calling keeps their bluffs and draws in the pot without bloating it against their stronger hands.

Queen-high has little showdown value against Ace-high draws and pairs, but my turn lead credibly represented a straight or strong made hand and the river is a blank, so continuing with a pot-sized pressure bet gives the best chance to win.

Top pair with a good kicker. The 2000 call into a 6850 pot needs only about 29% equity, and missed diamond draws that led the turn give enough bluffs to justify calling.

Offsuit weak Broadway-low combo (T8o) from the button facing a raise isn't worth playing out of position isn't applicable here, but it's a marginal hand; folding preserves chips for better spots.

2-4 offsuit is near the bottom of the range and I would be out of position postflop against the big blind, so completing is not profitable.

J8o is playable on the button in 3-handed play; raising applies pressure to the blinds and lets me play in position rather than limping or folding.

QJo in the small blind against a wide 3-handed button open is a decent 3-bet candidate. Raising avoids playing out of position multiway with the big blind behind, and it applies fold equity against the button's wide range.

J8 offsuit is too weak to continue against a large SB 3-bet to 1000; calling 750 needs about 36% equity which this dominated hand lacks even in position.

Q7s is a standard button open in 3-handed play, and a 2.5bb raise pressures both blinds.

2h7h is weak offsuit junk facing a raise; not worth continuing from the small blind.

8-4 offsuit is very weak facing a button raise to 250; calling 150 from the big blind has poor equity and playability.
