if I make it 1500 and the BB or SB moves in, i am pot committed with 74o. Folding is an option (probably best, altho id rather have 74o than A4o), certainly. Bet size has been addressed. 900 was table standard, blinds were high, it was an effective bet with any two, and i wanted to control the size of the pot. there is something to be said for bringing a knife to a knife fight. ie. why bet 1500 when 900 had been effective?
