Hold'em table

6-5 suited on the button in a 3-handed game is a good speculative hand. Calling 100 to win a 250 pot gets a good price and keeps the pot small out of position against the blinds.

T9o is playable enough to complete the small blind for 50 into a 250 pot after a button limp, with the big blind still to act. Calling keeps the price cheap rather than bloating the pot out of position.

K2o is a weak hand in 3-player hold'em, and both opponents have already called. With no position advantage and poor hand strength, folding preserves chips for better opportunities rather than playing a marginal hand out of position.

I flopped trip tens and only the button remains after a limp. A small value bet builds the pot while keeping worse pairs and draws in.

I have a gutshot-plus-backdoor draw (5h6h on 7-T-T: open-ended-ish with 7 and 5-6, needs 8/9 for a straight) and the price is good: 200 to win 500 with position. Calling keeps me in cheaply, and the SB's 200 bet is small enough that raising isn't necessary.}

I have trip tens on a paired board and the pot is unopened on the turn, so a half-pot value bet gets called by worse tens, pairs, and draws.

I have a straight-flush-less open-ended straight draw (5-6 with 7 on board needs 3-4 or 8-9) plus a heart flush draw; the pot odds are 1150+450 to 450, about 3.5:1, so calling is profitable with roughly 15+ outs, though the paired board lowers some of that equity. Calling keeps the price right without bloating the pot.

I have tens full of deuces, which only loses to pocket deuces and chops with the one remaining ten. A pot-sized value bet targets worse hands that have called down.

I have 6-high with a missed straight draw on a paired board, so I can only beat a pure bluff. Seat 2 bet every street, and calling 1200 into a 2800 pot needs about 30% equity, which I don't have here.

Ace-deuce offsuit is weak but playable as a button open in three-handed; a small raise takes the initiative with position rather than calling or folding.

9-4 offsuit is a weak hand with poor win equity against a raiser. Folding from small blind against a raise is standard strategy with unprofitable holdings.

32o is the worst starting hand. Calling 150 to win a pot of 400 gives roughly 27% pot odds, but I would be out of position with almost no equity against a button raise, so folding is best.

Jack-two offsuit is a weak holding in early position (button/out-of-position). Folding minimizes losses against two opponents in the blinds who likely have better hand equity. Preserving chips is important in a 3-player format.

3-8 offsuit is a weak hand. Calling 50 more out of position against the big blind is marginal at best, and folding is the cleaner choice.

T7 offsuit is a weak hand out of position against two players behind, and calling 100 to see a flop with it has negative expected value. Folding is the simplest choice.

74o is too weak to continue heads-up for another half blind against the big blind.

Seven-five offsuit is too weak to open from the button for a full big blind, so folding preserves chips.

Jack-eight suited is a reasonable hand in position on the button. Raising to 3BB applies pressure and builds the pot while maintaining positional advantage postflop.

Q6 offsuit out of position in the small blind facing a button raise to 3bb, with the big blind still to act behind, is a clear fold.

94 suited is too weak to continue out of position against a button open after the small blind folds.
