Comparing the draw with the bet

Your draw is priced at 33.33% and it arrives just 24.14% of the time. A gap of 9.19 points is large, and later bets would have to be large to make up for it.

Over many identical spots, with the whole pot won on every hit, the call lost on every miss and no extra betting, calling loses $27.57 on average. Hits bring in $48.29, misses cost $75.86, and the ratio is -0.276 per dollar called.

Odds say the same thing. Hitting is 3.14 : 1 against, and the pot lays 2 : 1.

Do not forget your own call. Dividing the bet by the pot without it gives 50.00%, not 33.33%, and would show a margin of -25.8557 points.

The price with implied odds

Break-even needs $114.18 of future winnings on top of the $300 already in the pot, which is 1.14 times the cost of your call.

Reaching 33.33% takes 9 outs on the flop, which hit 34.97%. With 6, the distance is 3 outs.

How this is computed

The chance rests on counting, not on a rule of thumb. Blank pairs: 820 out of 1,081; hit chance: 24.14%.

The numbers are a baseline rather than a prediction for one hand. The price is 33.33%, from $100 into $300, and the chance assumes a whole pot won on a hit, no more betting, 47 equally likely unseen cards, and no cards removed for the other player.
