If at the table there are 9 and 10 poker players and I have A, J and my opponent 10.5, who wins?

you seem more advantageous but who knows? its poker

The person who gets cards to help them at the flop, turn, and river.

The 10 5 or you would not have started this thread!

I am guessing it ended up like my prom night.

A girl asked me to go to prom with her, I finally agreed thinking at least I would get be rewarded for it at the end of the night and she ended up being a lesbian.

Most of the time the winner of the hand will be one of the other 7 or 8 players. The player with the 10 5 should not win very often since he will be folding preflop most of the time.

Probably the one who has the best hand will win.

Most times (about 60 - 70%) AJ is the winning hand. But sometimes (about 40-30%) T5 could be the best hand on the river.

Of course 10 5 will win. Poker loves to joke like that

Whoever is more aggressive before the flop wins, because with T5 the opponent will fold.
