Playing Hold'em poker and had a 10-J in hand, 9-Q-A on the table. Opponent held A-4 and won with a pair of A's. I thought I would win with the straight. Not so?
I don't know what a wheel of straight means, but not having a full straight of 5 cards in a row even 4 cards is worth nothing besides high Card. Your value was High Card A (which is on board already)
A straight means 5 Cards in a row, so you missed a 8 or a K.
He wins with pair of AA , that's correct.
A wheel or is the name for the low straight ( A-2-3-4-5 )
A steel wheel is the name for the lowest straight flush (A-2-3-4-5)
