re: Poker & how where the odds to win
Nothing wrong at all. Pocket A's are a great hand, they are pretty to look at (especially with the A of Spades), but they ARE NOT guaranteed winners. At best, heads-up they are what - 70/30 favorites against any 2 cards. You WILL lose 30% of the time, of course that would be over millions of hands.
When you tally up the heads-up and multi-player hands combined, that average probably falls to about 60/40 or less.
All-in preflop? Depends on the table, players, position, etc. Sometimes you'll just steal the blinds and never get value. Other times you'll get 5 callers and 3 of them will beat your rockets. I still prefer to play them as any other premium hand. After all - they are only 2 cards - one pair.
If you don't mind betting the farm - and losing the farm - at least 30% of the time, then go all-in preflop every chance you get.
