Villain in this hand is a very ABC player who has trouble letting go of big pairs on dry-ish boards. His early position preflop stats are moderately tight, so Hero can easily put him on a big hand. Call it TT+, AQ+, and maybe KQs. Hero's 44 is clearly behind this range, but if it improves on flop he's likely to get paid off. Said another way: stacks are 100BB deep, and because Villain gets married to what he considers big hands, Hero is getting good implied odds to call to hit a set or better... and voila, Hero hits gin on the flop, and the rest is an exercise in getting paid off.
All-in for now...
